美丽中国与国土空间规划关系的地理学思考

The concept of‘Beautiful China'is a new goal of ecological construction in the new era of socialism and aims to meet the needs of people as they strive for a better life.National land spatial planning is one major component of the Chinese state's overall planning for various spatial types.The concept of‘Beautiful China'is thus a leading goal of Chinese development in the second centenary.The background of this concept aims for‘ecological beauty'as well as the combined beauty of‘economy-politics-culture-society-ecology.'The construction of‘Beautiful China'therefore necessitates a differentiated evaluation index system that is built on the basis of local conditions.This concept is intimately related to land spatial planning and the idea of Beautiful China guides an important direction for this planning which itself provides an important mechanism and spatial guarantee for construction.The establishment of land spatial planning nevertheless needs to strengthen further discussion of the regional system of human-land relationship,point axis system,main functional division,sustainable development,resources and environmental carrying capacity as well as new urbanization,and the rural multi-system.The aim of this paper is to summarize current thinking in land spatial planning,scientifically analyze the natural geographical conditions,the socioeconomic development,the interrelationship of the land space,plan the goal,vision and path of land space,encourage the public to participate in and carry out dynamic evaluation,build an intelligent system platform for land and spatial planning to realize the goal of‘Beautiful China'from a geographical perspective.And they can also present key ideas relating to the compilation and implementation of land spatial planning.     

Land consolidation: An indispensable way of spatial restructuring in rural China1简

The implementation of new type industrialization and urbanization and agricultural modernization strategies lacks of a major hand grip and spatial supporting platform, due to long-term existed ＂dual-track＂ structure of rural-urban development in China as well as un- stable rural development institution and mechanism. It is necessary to restructure rural pro- duction, living and ecological space by carrying out land consolidation, so as to establish a new platform for building new countryside and realizing urban-rural integration development in China. This paper develops the concept and connotation of rural spatial restructuring. Basing on the effects analysis of industrialization and urbanization on rural production, living and ecological space, the mechanism of pushing forward rural spatial restructuring by carry- ing out land consolidation is probed. A conceptualization of the models of rural production, living and ecological spatial restructuring is analyzed combining with agricultural land con- solidation, hollowed villages consolidation and industrial and mining land consolidation. Fi- nally, the author argues that a ＂bottom-up＂ restructuring strategy accompanied by a few ＂top-down＂ elements is helpful for smoothly pushing forward rural spatial restructuring in China. In addition, the optimization and restructuring of rural production, living and ecological space will rely on the innovations of regional engineering technology, policy and mechanism, and mode of rural land consolidation, and more attentions should be paid to rural space, the foundation base and platform for realizing urban-rural integration development.     

Designing a spatial pattern to rebalance the orientation of development and protection in Wuhan

Patterns of spatial development and protection form a basic category of geoscience,and redesigning them is a popular subject of research in regional sustainable development that is important for ecological civilization construction.The authors here report a case study of Wuhan city using the circuit theory model and minimum cumulative resistance(MCR)model to rebalance its spatial protection and development.The results show the following:(1)Using the density of the gross domestic product(GDP),density of population,rate of urbanization,and access to transportation as evaluation indicators,seven core areas of development in Wuhan were identified,accounting for 59%of the total number of streets,that exhibited a “circular-satellite”spatial structure.(2)According to the importance of ecosystem services,ecological sensitivity,land use type,and slope of the terrain,the resistance surface of spatial development in Wuhan had a stereoscopic spatial form of an“inverted pyramid,”with high surroundings and a low center.The area of low resistance accounted for 6.64%of the total area of Wuhan.(3)Based on coupling analysis using the MCR and spatial morphological characteristics of current,nine axes of spatial development with a total area of 427.27 km2 and eight key strategic points with a total area of 40.02 km2 were identified.Streets that were prioritized for development accounted for 9.63%of Wuhan's total area.(4)By combining the characterization of the development axis with the structure of the three-level core area,we extracted the structure of spatial development of "one heart,two wings,and three belts" in Wuhan.The research framework and empirical results can provide scientific guidance for the urban spatial layout,the development of regional linkages,and ecological environmental protection in China.     

中国西南地区纵向岭谷地形对区域生态地理格局的作用(英文)

China’s southwestern special terrain pattern as parallel arrangement between longitudinal towering mountains and deep valleys has significant effects on the differentiation of local natural environment and eco-geographical pattern in this region.The 1:50,000 Digital Elevation Model(DEM) data of Longitudinal Range-Gorge Region(LRGR),meteorological observation data from the station establishment to 2010,hydrological observation data,Normalized Difference Vegetation Index(NDVI) and Net Primary Productivity(NPP) products of MOD13 and MOD17 as well as 1:1,000,000 vegetation type data were used.Moisture indices including surface atmospheric vapor content,precipitation,aridity/humidity index,surface runoff,and temperature indices including average temperature,annual accumulated temperature,total solar radiation were selected.Based on ANUSPLIN spline function,GIS spatial analysis,wavelet analysis and landscape pattern analysis,regional differentiation characteristics and main-control factors of hydrothermal pattern,ecosystem structure and function in this region were analyzed to reveal the effects of terrain pattern on regional differentiation of eco-geographical elements.The results show that:influenced by terrain pattern,moisture,temperature and heat in LRGR have shown significant distribution characteristics as intermittent weft differences and continuous warp extension.Longitudinal mountains and valleys not only have a north-south corridor function and diffusion effect on the transfer of major surface materials and energy,but also have east-west barrier function and blocking effect.Special topographic pattern has important influences on vegetation landscape diversity and spatial pattern of ecosystem structure and function,which is the main-control factor on vegetation landscape diversity and spatial distribution of ecosystem.Wavelet variance analysis reflects the spatial anisotropy of environmental factors,NDVI and NPP,while wavelet consistency analysis reveals the control factors on spatial distribution of NDVI and NPP as well as the quantitative relationship with control degree.Special terrain pattern in LRGR is the major influencing factor on eco-geographical regional differentiation in this region.Under the combined effect of zonality and non-zonality laws with "corridor-barrier" function as the main characteristic,special spatial characteristics of eco-geographical regional system in LRGR is formed.     

中国省域间生态地租分异特征及其影响因素(英文)

Ecological land rent is the excess profit produced by resource scarcity, and is also an important indicator for measuring the social and economic effects of resource scarcity. This paper, by calculating the respective ecological land rents of all the provinces in China for the years 2002 and 2007, and with the assistance of the software programs ArcGIS and GeoDA, analyzes the spatial differentiation characteristics of ecological land rent; then, the influencing factors of ecological land rent differentiation among the provinces are examined using the methods of traditional regression and spatial correlation analysis. The following results were obtained: First, ecological land rent per unit of output in China shows stable distribution characteristics of being low in the southwestern and northeastern provinces, and high in Hebei and Henan provinces. There is also an increasing tendency in the central and western provinces, and a decreasing one in the eastern provinces. In general, the spatial distribution of ecological land rent per unit of output in China is quite scattered. Second, the total ecological land rent shows significant spatial aggregation characteristics, in particular the provinces in China possessing high total amounts of ecological land rent tend to be adjacent to one another, as do those with low total amounts, and the spatial difference characteristics of the eastern, central and western provinces are distinguished. The Bohai Rim, Yangtze River Delta and Pearl River Delta are shown to be highly clustering regions of total ecological land rent, while the western provinces have very low ecological land rent in terms of total amount. Third, population distribution, economic level and industrial structure were all important influencing factors influencing ecological land rent differentiation among provinces in China. Furthermore, population density, urbanization level, economic density, per capita consumption level and GDP per capita were all shown to be positively related to total ecological land rent, which indicates that spatial clustering exists between ecological land rent and these factors. However, there was also a negative correlation between ecological land rent and agricultural output percentage, indicating that spatial scattering exists between ecological land rent and agricultural output percentage.     

中国农村地区房屋结构及其脆弱性的分析(英文)

The damage of dwelling houses constitutes the primary cause of casualties and asset loss in seismic disasters that occurred in Chinese rural areas. The structure of houses is crucial for assessing the vulnerability of rural houses. However, at present, available data on rural housing structure are incomplete and their spatial scales are inconsistent. This paper estimated the amount and ratio of rural houses in five structures, namely ’wood’, ’brick’, ’mixed’, ’reinforced concrete’, and ’other’, for 2380 counties across China. With the percent-age sampling census data in 2005, four accuracy levels were specified. Then, a set of down-scaling models were established, where the impact of climate, economic development level and ethnic minority cultural factors on rural housing structure, as well as the spatial autocorrelation of neighboring spatial units were considered. Based on the estimation results, a database of county-level rural housing structure was established, based on which the vul-nerability of rural houses in different areas was clarified.     

全球粮食安全格局的时空演化

Food security is the primary prerequisite for achieving other Millennium Development Goals(MDGs).Given that the MDG of“halving the proportion of hungers by 2015”was not realized as scheduled,it will be more pressing and challenging to reach the goal of zero hunger by 2030.So there is high urgency to find the pattern and mechanism of global food security from the perspective of spatio-temporal evolution.In this paper,based on the analysis of database by using a multi-index evaluation method and radar map area model,the global food security level for 172 countries from 2000 to 2014 were assessed;and then spatial autocorrelation analysis was conducted to depict the spatial patterns and changing characteristics of global food security;then,multi-nonlinear regression methods were employed to identify the factors affecting the food security patterns.The results show:1)The global food security pattern can be summarized as“high-high aggregation,low-low aggregation”.The most secure countries are mainly distributed in Western Europe,North America,Oceania and parts of East Asia.The least secure countries are mainly distributed in sub-Saharan Africa,South Asia and West Asia,and parts of Southeast Asia.2)Europe and sub-Saharan Africa are hot and cold spots of the global food security pattern respectively,while in non-aggregation areas,Haiti,North Korea,Tajikistan and Afghanistan have long-historical food insecurity problems.3)The pattern of global food security is generally stable,but the internal fluctuations in the extremely insecure groups were significant.The countries with the highest food insecurity are also the countries with the most fluctuated levels of food security.4)The annual average temperature,per capita GDP,proportion of people accessible to clean water,political stability and non-violence levels are the main factors influencing the global food security pattern.Research shows that the status of global food security has improved since the year 2000,yet there are still many challenges such as unstable global food security and acute regional food security issues.It will be difficult to understand these differences from a single factor,especially the annual average temperature and annual precipitation.The abnormal performance of the above factors indicates that appropriate natural conditions alone do not absolutely guarantee food security,while the levels of agricultural development,the purchasing power of residents,regional accessibility,as well as political and economic stability have more direct influence.     

历史时期中国重大自然灾害时空分异特征(英文)

Based on historical documents and records this paper analyzes the characteristics of frequency and distribution of major disasters that took place in the history of China. The findings show that occurrences of different types of disasters varied and spatial pattern at provincial level are significantly different as well. The results also indicate that there is a strong relationship between type of disasters and spatial distribution and that the spatial pattern of losses was not the same as that of the frequency. The reasons are: (1) the hazard-formative environments which, to a large extent, determine the spatial pattern of the disasters are significantly different; (2) the losses caused by natural disasters were closely related to the concentration of economy and population. Number of deaths was usually large in areas where agriculture, culture and business were relatively developed. The spatial pattern of disaster losses is an evitable result of uneven economic development in the history of China.     

长株潭城市群地区乡村功能的动态演变及驱动机制（英文）

As the Rural Revitalization Strategy is gradually implemented, China's rural areas are set to have more diverse function requirements. This paper selects the Changsha-Zhuzhou-Xiangtan region(Chang-Zhu-Tan) consisting of 23 county-level units) as a case study and looks at its economic development, agricultural product supply, social security and ecological service functions during 1996–2016. It then constructs an index system to evaluate the temporal evolution of the region's rural functions. SPSS 19.0 and DPS 7.05 software, as well as Pearson's correlation coefficient analysis, system clustering, optimal segmentation of ordered samples and other methods, are used to study the evolution traits, regional differentiation characteristics and driving forces of rural functions in the region. The results show, first of all, that the overall evolution trend is increasing in functions with periodic characteristics, the key nodes being 2000 and 2008. Second, there is clear geographical differentiation in the evolution of rural functions. The economic development function shows rapid growth in the urban agglomeration's center and relatively weak growth at the periphery; the agricultural product supply function and ecological service function are concentrated in county-level units with abundant cultivated and forest land; and the social security function displays similar geographical differentiation to the economic development function. Overall, there is an obvious discrepancy in the degree of development of rural functions among county-level units of the Changsha-Zhuzhou-Xiangtan urban agglomeration; the rural functions of the agglomeration and peripheral county-level units have different development traits; and county-level units display functional differentiation. Third, rural functions have evolved as a result of interactions between various factors, such as natural resources, socio-economic conditions and local transport conditions. The new driving forces caused by urbanization are ultimately leading the evolution of rural functions toward multi-functional comprehensive development.     

海南岛热带林区生态系统评估与保护成效（英文）

Ecosystem services have become one of the core elements of ecosystem management and evaluation. As a key area of ecosystem services and for maintaining national ecological security, ecosystem changes and implementation effect evaluation are important in national key ecological function zones, for promoting the main function zone strategy and for improving the construction of an ecological civilization. This article studies the ecological zone of a tropical rainforest region in the central mountain area of Hainan Island, China. Multi-source satellite data and ground observation statistics are analyzed with geo-statistics method and ecological assessment model. The core analysis of this paper includes ecosystem patterns, quality and services. By means of spatial and temporal scale expansion and multidimensional space-time correlation analysis, the trends and stability characteristics of ecosystem changes are analyzed, and implementation effect evaluation is discussed. The analysis shows a variety of results. The proportion of forest area inside the ecological zone was significantly higher than the average level in Hainan Island. During 1990–2013, settlement gradually increased inside the ecological zone. After implementation of the zone in 2010, human activity intensity increased, with the main land use being urban construction and land reclamation. Water conservation in the ecological function zone was higher than that outside the zone. In general, it increased slightly, but had obvious fluctuations. Soil conservation inside the zone was also better than that outside. However, it demonstrated dramatic fluctuations and relatively poor stability during 1990–2013. The human disturbance index inside the zone was significantly lower than that outside, and had a lower biodiversity threat level. Especially in 2010–2013, the increased range of the human disturbance index inside the zone was significantly less than that outside.     

基于中国主体功能区划的国家与省级点-轴结构解析

中国主体功能区划作为国土空间开发保护的基础制度,其空间结构是各级各类空间规划遵循的重要约束性指标以及主体功能区精准落地的关键参数。本文将面状功能区纳入点-轴系统结构,探索主体功能区点-轴结构的科学内涵,以中国主体功能区划为研究对象,聚焦国家与省级层面,着重从主体功能区点-轴结构的要素构成、功能区与点-轴结构的空间分异、以及功能区与点-轴结构的相互作用三个方面进行解析。研究结果表明：① 中国主体功能区划这张图本身就蕴含着点-轴系统结构,城市化地区是不同等级极核的集合,极核的等级和空间分布决定了开发轴线;② 点-轴地域开发系统、农业发展和生态安全地区呈现圈层式的结构特征,随着距离轴线越远,城市化类型比重越低、生态安全类型比重越高,点-轴结构受粮食安全与生态安全保障需求的约束;③ 无论是国家和省级层面,联系最紧密的区域连线与开发轴线基本吻合,不同层级等级较高的城市化功能主导区域之间的相互作用决定了主体功能区点-轴的拓扑结构,这在自然约束较弱、人类活动相对强度的区域更为显著。本文的研究成果有助于科学认知主体功能区的科学内涵及有序化的空间组织规律,为国土空间规划及功能区降尺度传导提供关键指标与参数,也将为中国综合地理区划提供重要的参考。     

中国主体功能区核心—边缘结构解析

中国主体功能区划作为一张综合展示未来中国国土开发与保护格局的前景图,实际上是城市化地区、农业发展地区和生态安全地区三者按照一定法则和规律构成并演化着,维持着中国国土开发的有序性。本文以城市化地区、农业发展地区和生态安全地区三者比例关系、采用特征点—轴—面—向量测度核心—边缘结构的整体格局和内部结构差异,从自然地理空间分异、社会经济空间组织和功能区相互作用三个维度解析。结果表明,全国各个省域普遍存在核心—边缘结构,即城市化地区、农业发展地区和生态安全地区三者的比例关系随着到核心的距离呈现圈层式的空间分异规律,但核心位置、轴线走向、边缘功能属性、内部功能占比等有所差异。西部省份以城市化、农业发展和生态安全圈层分异明显,几乎所有的生态安全地区被指向为边缘地区;中部省份边缘区域农业发展占比有所增加,而沿海省份普遍存在多个核心,城市化地区主导核心区域。通过因素解析可知,主体功能区核心—边缘结构由自然地理空间分异、社会经济空间组织和区域空间联系等综合作用产生。西部省份核心—边缘受主要地理界线影响较大,东部平原地区核心—边缘受已有城镇体系结构、社会经济的布局、区域联系强度影响较大。自然地理环境约束越弱的区域,社会经济发展以及区域联系强度的影响愈加显著。

Spatial heterogeneity of urban land-cover landscape in Guangzhou from 1990 to 2005

Urbanization has been the most important process that changed land cover landscape in Guangzhou since reformation, especially since 1990. It is essential for monitoring and assessing ecological consequences of urbanization to understand landscape quantitative characteristics and its changes. Based on four land-cover type maps interpreted from remote sensing TM images of 1990, 1995, 2000 and 2005, combining gradient analysis with landscape metrics, the quantified spatial pattern and its dynamics of urbanization in Guangzhou was got. Three landscape metrics were computed within different regional areas including the whole study area, two transects along two highways (one N–S and the other W–E) and radiation zones with equal distance outwards the city center were set. Buffer zones for transects N–S and W–E were outlined along highways. The following questions should be answered in this paper: What responses were implied with changing spatial grain size or extent for landscape pattern analysis? Could gradient progress of urbanization be characterized by landscape pattern analysis? Did landscape metrics reveal urban expanding gradually? Were there directional differences in land cover landscape pattern during urbanizing development? The results gave some affirmative answers. Landscape pattern exhibited obviously scale-dependent to grain size and extent. The landscape metrics with gradient analysis could quantitatively approach spatial pattern of urbanization. A precise location for urbanized area, like city center and sub-center, could be identified by multiple landscape metrics. Multiple adjunctive centers occurred as indicated by analysis of radiation zones around the city center. Directional differences of landscape pattern along the two transects (N–S and W–E) came into being. For example, fragmentation of landscape in the transect W–E was obviously higher than that in the transect N–S. All in all, some interesting and important ecological implications were revealed under landscape patterns of two transects or radiation zones, and that was the important step to link pattern with processes in urban ecological studies and the basis to improve urban environment.     

中国城镇人口“镇化”发展的时空分异

将中国人口城镇化细分为城镇人口“镇化”与“城化”,采用“镇化水平”和“镇化贡献率”两个指标,从不同空间尺度及主体功能区视角,系统分析1982-2015年中国城镇人口镇化发展的时空分异及影响因素。主要结论包括：① 中国的城镇人口“镇化水平”和“镇化贡献率”在不断提升。2015年镇化水平为41.8%,2010-2015年期间镇化贡献率为55.1%。② 中国城镇人口镇化呈现显著的时空分异特征。镇化主导型县市主要分布在中西部地区,占全国国土面积的70%以上;城化主导型县市主要集中分布在沿海城市群地区,在全国国土面积中所占比例较小。③ 展望未来,中国城镇人口的镇化贡献率和镇化水平将稳中趋缓,应加强探索出基于主体功能区域分异的差异化小城镇发展模式。

基于主体功能区视角下新疆民生质量的区域差异及影响因素

主体功能区定位决定区域的发展方向和重点,各类型区逐步实现公共服务均等化,民生质量发展表现出一定的区域差异。本文基于新疆主体功能区规划和民生发展实际状况构建民生质量评价指标体系,运用熵值法计算2005 年和2014 年各主体功能类型区的民生质量,并结合差异贡献率动态分析各类型区民生差异的影响因素。结果表明：（1）各类型区民生质量存在显著差异,重点开发区最优,重点生态功能区最低;尤其是收入与消费、文化与教育和生态与环境方面水平差距日益拉大。（2）各类型区民生质量发展侧重点各有不同,在文化与教育方面呈现水平共同下滑趋势。（3）各因素对于影响类型区民生质量差异的作用效果不同,收入、消费、交通设施、信息化、医疗卫生和生态平衡水平等成为拉大民生差距的主要因素。（4）收入消费水平和交通设施水平对拉大类型区民生质量差距的强度最为突出,生态平衡水平和信息化水平对拉大差距的程度逐渐加强,社会保障水平和教育水平对缩小差距的作用最强。基于上述分析,对缩小新疆主体功能区民生发展差距,保障基本公共服务均等化提出相应对策建议。     

面向国土空间优化的三生空间研究进展

解决经济高速增长、社会快速转型中存在的国土开发秩序混乱和资源环境代价沉重等问题是人文—经济地理学在区域可持续发展领域的重大科学命题。党的十八大报告将优化国土空间开发格局作为生态文明建设的首要举措,并提出“促进生产空间集约高效、生活空间宜居适度、生态空间山清水秀”,由此构成的“三生”空间成为构建空间规划体系、完善国土空间开发保护制度和各类尺度空间落实主体功能区规划的重要基础。本文围绕国土空间优化和区域可持续发展目标,对国内外“三生”空间相关文献进行系统梳理,紧紧围绕“三生”空间的数量配比和空间配置两个科学问题进行综述,按照精度深化和尺度细化的要求,集中在“三生”功能分类、空间识别、空间优化等内容,从而勾勒出三生空间研究的框架体系。今后应重视三生空间动态演化,促进各尺度适宜性评价的统一和整合,响应“多规合一”的实践需求,最终服务于国土空间格局优化。     

海岛(县)主体功能区划分的研究——以浙江省玉环县、洞头县为例

海岛是海中陆地,一个海岛包括岛陆、岛基、岛滩和海岛周围的海域。地域主体功能区划主要强调国土空间开发的分工和布局,要求做到国土的全覆盖。海岛县是海陆国土空间复合系统,同陆域县区一样,根据资源环境承载能力、现有开发密度和发展潜力,统筹考虑未来人口分布、经济布局、国土利用和城镇化格局,将国土空间划分为优化开发、重点开发、限制开发和禁止开发四类主体功能区。在已有陆域主体功能区划和海洋功能区划等理论的基础上,考虑陆域要素与海域要素,应用层次分析、多指标综合加权评价法和主成分-聚类分析等主要量化方法,把地理空间思想融入分析框架中,做到定性与定量相结合,从而划分出玉环和洞头二个海岛县海陆国土空间复盖的主体功能区划。陆域主体功能区与海洋主体功能区要相互衔接,主体功能定位相互协调。
