黄淮海平原农区土地利用转型及其动力机制(英文)   总被引:7,自引:0,他引:7  
Land use transition refers to changes in land use morphology, including dominant morphology and recessive morphology, of a particular region over a period of time driven by various factors. Recently, issues related to land use transition in China have attracted interest among a wide variety of researchers as well as government officials. This paper examines the patterns of land use transition and their dynamic mechanism in the Huang-Huai-Hai Plain during 2000–2010. First, the spatio-temporal patterns of land use transition, their characteristics and the laws governing them were analyzed. Second, based on the established conceptual framework for analyzing the dynamic mechanism of land use transition, a spatial econometric regression analysis method was used to analyze the dynamic mechanism of the five types of major land use transition in the Huang-Huai-Hai Plain at the county level. Land use pattern changes in the study area were characterized by an increase in construction land, water body and forested land, along with a decrease in farmland, unused land and grassland. The changes during 2000–2005 were much more significant than those during 2005–2010. In terms of factors affecting land use transitions, natural factors form the basis, and they have long-term effects. Socio-economic factors such as population and GDP, however, tend to determine the direction, structure, size and layout of land use transition over shorter time periods. Land law and policy factors play a mandatory guiding and restraining role in land use transitions, so as to improve the overall efficiency of land use. Land resource engineering is also an important tool to control land use transitions. In general, the five types of major land use transition were the result of the combined action of various physical, social and economic factors, of which traffic condition and location condition had the most significant effects, i.e. they were the common factors in all land use transitions. Understanding the spatio-temporal process of land use transitions and their dynamic mechanisms is an important foundation for utilizing land resources, protecting regional ecological environment and promoting sustainable regional socio-economic development.  相似文献

The cultivation of mountainous land results in water loss and soil erosion. With rapid urbanization and industrialization in China, labor emigration relieves the cultivation of mountainous areas in regions with high poverty and leads to a significant land use transition. This research built an analysis framework for "land use transition – driving mechanism – effects –responses" for mountainous areas of China undergoing land use transition and then proposed the direction of mountainous land consolidation. The results showed that the turning point of land use morphology was the core of rural land use transition in mountainous areas. The expansion of cropland and the contraction of forestland have transitioned to the abandonment of cropland and the expansion of forestland; this transition was the main characteristic of the dominant land use change. Land marginalization and land ecological functional recovery were the main characteristics of the recessive land use transition in mountainous areas. Socioeconomic factors were the primary driving forces during land use transition in mountainous areas, with labor emigration being the most direct force. The rising costs of farming and the challenging living conditions causing labor emigration were fundamental driving forces. Rural land use transition in mountainous areas reduced the vulnerability of the ecological function of land ecosystems. The advantages and disadvantages of the socioeconomic effects should focus on rural development of mountainous areas as well as the livelihood of farmers; this should be further supported by empirical and quantitative research. Rural land use transition of mountainous areas improves natural restoration and is related to socioeconomic development. Rural land consolidation of mountainous areas should conform to land use transition,with the goal of shifting from the increase of cultivated land to the synergies of ecological and environmental protection.  相似文献

Land use/cover change has been recognized as a key component in global change and has attracted increasing attention in recent decades. Scenario simulation of land use change is an important issue in the study of land use/cover change, and plays a key role in land use prediction and policy decision. Based on the remote sensing data of Landsat TM images in 1989, 2000 and 2010, scenario simulation and landscape pattern analysis of land use change driven by socio-economic development and ecological protection policies were reported in Zhangjiakou city, a representative area of the Poverty Belt around Beijing and Tianjin. Using a CLUE-S model, along with socio-economic and geographic data, the land use simulation of four scenarios–namely, land use planning scenario, natural development scenario, ecological-oriented scenario and farmland protection scenario–were explored according to the actual conditions of Zhangjiakou city, and the landscape pattern characteristics under different land use scenarios were analyzed. The results revealed the following:(1) Farmland, grassland, water body and unused land decreased significantly during 1989–2010, with a decrease of 11.09%, 2.82%, 18.20% and 31.27%, respectively, while garden land, forestland and construction land increased over the same period, with an increase of 5.71%, 20.91% and 38.54%, respectively. The change rate and intensity of land use improved in general from 1989 to 2010. The integrated dynamic degree of land use increased from 2.21% during 1989–2000 to 3.96% during 2000–2010.(2) Land use changed significantly throughout 1989–2010. The total area that underwent land use change was 4759.14 km2, accounting for 12.53% of the study area. Land use transformation was characterized by grassland to forestland, and by farmland to forestland and grassland.(3) Under the land use planning scenario, farmland, grassland, water body and unused land shrank significantly, while garden land, forestland and construction land increased. Under the natural development scenario, construction land and forestland increased in 2020 compared with 2010, while farmland and unused land decreased. Under the ecological-oriented scenario, forestland increased dra-matically, which mainly derived from farmland, grassland and unused land. Under the farmland protection scenario, farmland was well protected and stable, while construction land expansion was restricted.(4) The landscape patterns of the four scenarios in 2020, compared with those in 2010, were more reasonable. Under the land use planning scenario, the landscape pattern tended to be more optimized. The landscape became less fragmented and heterogeneous with the natural development scenarios. However, under the ecological-oriented scenario and farmland protection scenario, landscape was characterized by fragmentation, and spatial heterogeneity of landscape was significant. Spatial differences in landscape patterns in Zhangjiakou city also existed.(5) The spatial distribution of land use could be explained, to a large extent, by the driving factors, and the simulation results tallied with the local situations, which provided useful information for decision-makers and planners to take appropriate land management measures in the area. The application of the combined Markov model, CLUE-S model and landscape metrics in Zhangjiakou city suggests that this methodology has the capacity to reflect the complex changes in land use at a scale of 300 m×300 m and can serve as a useful tool for analyzing complex land use driving factors.  相似文献

Land use change in Bohai Rim: a spatial-temporal analysis   总被引:5,自引:0,他引:5  
Land use change is one of the important aspects of global change[1-3]. The Bohai Rim is a hot spot of economic development in China, where land use changes remarkably. Analyzing land use change in this area is significant to the research of global change and regional sustainable land use. Although there has been much work undertaken on regional land use change in China, it was mainly on urban land use change[4-11], and few researches integrated remote sensing and GIS method.

With the introduction of the concept of land use transition into China, related researches have been carried out extensively in the past two decades, which enrich the knowledge of land system science. This paper describes the development of research on land use transitions in China from the perspectives of conceptual connotations, theoretical model, research methods, and research progress and prospects. With the in-depth investigation of land use transitions, the concept and connotations of land use morphology are developed and encapsulated as two kinds, i.e., dominant morphology and recessive morphology. The dominant morphology refers to the land use structure of a certain region over a certain period of time, with features such as the quantity and spatial pattern of land use types. While the recessive morphology includes the land use features in the aspects of quality, property rights, management mode, input, output and function. Accordingly, the concept of land use transition is further developed, and the theoretical model of regional land use transitions is established. Thereafter, three innovative integrated approaches to study land use transitions are put forward, i.e., multidisciplinary research framework for recessive land use transition, transect and horizontal comparison. To date, there have been 62 Ph.D. and 166 M.S. dissertations on the topic of "land use transition" in China. During 2002–2019, the National Natural Science Foundation of China has funded 48 research programs on the theme of "land use transition". As such, the Chinese scholars have adapted the concept derived from western literature to the situations and experiences in China.  相似文献

Understanding the driving forces and mechanism of land use change is a key issue in land change science, and has received much attention over the past 30 years. While many driving forces have been identified, the mechanism of land use change is still unclear, mainly because of limited knowledge of the underlying motivation for land use change. Traditionally, the underlying motivation for land use change was ascribed to people's pursuit of satisfying their own demands or that of profit maximization. However, those theoretical hypotheses combine all productive factors without highlighting certain predominant factor, in this paper, a case study was conducted on the variation of land productivity, capital productivity and labor productivity in agricultural land use in Xinjiang Uygur Autonomous Region of China. The case study revealed that only labor productivity presented a long-term increasing trend in regional cotton and grain production. This result implies that people's pursuit of increasing labor pro- ductivity is probably the underlying motivation for land use change. Additional details identi- fied in agricultural and non-agricultural land use in China support the above implication. As labor productivity is a determinant of people's living standards, increasing labor productivity means improving people's living standards. Therefore, it is concluded that land use change results from people's pursuit of increasing labor productivity in a changing environment.  相似文献

农户的非农就业如何影响中国的土地流转?   总被引:1,自引:0,他引:1  
To clarify the impact of non-agricultural employment on rural land circulation in China,we built logit models using the Chinese Household Income Project 2013 dataset,which includes 18,948 household samples over 15 provinces,126 cities and 234 counties of China in 2013.We use the proportion of non-agricultural income,the proportion of non-agricultural laborers and non-agricultural fixed operating assets to reflect the degree of the households’dependence on agriculture,the degree of the households’laborers committed to non-agricultural employment and the stability of non-agricultural employment,respectively.The results show that the stability of non-agricultural employment is an important reason for farmers to transfer out their land,and an increase in non-agricultural income is the fundamental reason.The proportion of non-agricultural assets has the greatest impact on the decision to transfer land,followed by the proportion of non-agricultural income.Per unit increase in the non-agricultural income ratio has a stronger effect on the transfer-out decision than it does on the transfer-in decision,which is a 0.09 increase of the probability of transfer-out the land and a 0.07 decrease of the probability of transfer-in the land.In terms of regional differences,when considering the impact of non-agricultural employment on the land transfer-out decision,the impacts of non-agricultural income and labor force are the greatest in the Central region.The impact of non-agricultural assets is the greatest in the Eastern region.For the Eastern region,the decision to transfer out land is mainly affected by non-agricultural assets and the non-agricultural labor force,and the decision to transfer in land is mainly affected by non-agricultural assets.In the Central and Western regions,the decision to transfer out land is mainly affected by non-agricultural assets,non-agricultural income and the non-agricultural labor force,in that order.The decision to transfer in land in the Central region is not significantly affected by non-agricultural employment.The decision to transfer in land in the Western region is mainly affected by non-agricultural assets,non-agricultural labor force and non-agricultural income,in that order.We note that non-agricultural assets have a prominent impact on land transfer,which shows that the stability of non-agricultural employment has an important impact on land transfer decision-making.Vocational training for rural labor forces may be an effective means to promote stable non-agricultural employment and simultaneously facilitate rural land circulation,especially in Central and Western China.  相似文献

Rural tourism has become an important driving force of rural urbanization in China. As the main reception base and important tourism attraction, tourism village is the core element of the tourism destination system. Integrating the method of PRA(Participatory Rural Assessment), GIS technology and high-resolution remote sensing images, this study aims to analyze the spatial morphology evolution of rural settlements induced by tourism through a comparative study of three tourism villages in Yesanpo tourism area. The results suggest the emergence of a "core-periphery" pattern of the spatial evolution of rural settlements. The closer to the core scenic spot, the higher degree of land-use intensity the village shows, as well as the more mature tourism function and greater change in landscape pattern. In particular, Gougezhuang shows an increase of the floor area ratio from 0.17 to 0.44, with the most mature tourism function and the lowest authenticity index of 0.448. Liujiahe has gone through the largest increase in construction land area from 17.3564 ha to 34.1128 ha, with moderately mature tourism function and relatively stable authenticity index of 0.566. Shangzhuang has the lowest construction land scale and intensity, with the poorest tourism function and most well-preserved landscape authenticity index of 0.942. Overall, in terms of the spatial morphology, the three villages show the characteristics of "modern town", "semi-urbanization" and "traditional village" respectively, in corresponding to three land development types: "intensive reconstruction type", "enclave extension type" and "in situ utilization type". The spatial evolution patterns of these three villages imply the spatial characteristics of the touristization of traditional villages in different stages, and also have great representative value for the management of rural settlements in tourism areas in China.  相似文献

In areas with topographic heterogeneity, land use change is spatially variable and influenced by climate, soil properties, and topography. To better understand this variability in the high-sediment region of the Loess Plateau in which soil loss is most severe and sediment diameter is larger than in other regions of the plateau, this study builds some indicators to identify the characteristics of land use change and then analyze the spatial variability as it is affected by climate, soil property, and topography. We build two indicators, a land use change intensity index and a vegetation change index, to characterize the intensity of land use change, and the degree of vegetation restoration, respectively. Based on a subsection mean method, the two indicators are then used to assess the spatial variability of land use change affected by climatic, edaphic, and topographic elements. The results indicate that: 1) Land use changed significantly in the period 1998-2010. The total area experiencing land use change was 42,302 km2, accounting for 22.57%of the study area. High-coverage grassland, other woodland, and forest increased significantly, while low-coverage grassland and farmland decreased in 2010 compared with 1998.2) Land use change occurred primarily west of the Yellow River, between 35 and 38 degrees north latitude. The four transformation types, including (a) low-coverage grassland to medium-coverage grassland, (b) medium-coverage grassland to high-coverage grassland, (c) farmland to other woodland, and (d) farmland to medium-coverage grassland, were the primary types of land use change, together constituting 60% of the area experiencing land use change. 3) The spatial variability of land use change was significantly affected by properties of dryness/wetness, soil conditions and slope gradient. In general, land use changed dramatically in semi-arid regions, remained relatively stable in arid regions, changed significantly in clay-rich soil, remained relatively stable in clay-poor soil, changed dramatically in steeper slopes, and remained relatively stable in tablelands and low-lying regions. The increase in vegetation coincided with increasing changes in land use for each physical element. These findings allow for an evaluation of the effect of the Grain to Green Program, and are applicable to the design of soil and water conservation projects on the Loess Plateau of China.  相似文献

中国耕地和农村宅基地利用转型耦合分析   总被引:21,自引:2,他引:19

土地利用转型,即在社会经济变化和革新的驱动下,某一区域在一段时期内由一种土地利用形态转变为另一种土地利用形态的过程。在中国,耕地和农村宅基地乃土地利用转型的重要源头。本文综合利用2000 年和2008 年两期Landsat TM 影像解译土地利用数据及2000-2008 年国土资源部土地利用年度变更调查数据,分析了中国耕地和农村宅基地利用转型的时空耦合特征。研究表明:① 2000-2008 年期间,中国耕地面积与农村宅基地面积变化的相关系数为-0.921,呈现出明显的增减逆协同演进格局;② 耕地—宅基地变化相关系数与农村宅基地利用变化率的Spearman 等级相关分析结果表明,在耕地和农村宅基地利用的相互转化过程中,农村宅基地利用的变化起主导作用;③ 通过计算全国各省2000-2008 年间的耕地—宅基地变化耦合系数,发现期间耕地和农村宅基地利用变化耦合程度高的省份主要分布在胡焕庸线的东南部。社会经济—生物自然—土地管理三维驱动因素通过“农村人口—耕地—农村宅基地”三者之间的相互联系与相互作用驱动着耕地和农村宅基地利用的转型。然而,耕地和农村宅基地利用转型的时空耦合现象及其发生机制在很大程度上要归因于中国特殊的城乡二元结构社会体制。  相似文献

中国农村宅基地转型的理论与证实   总被引:52,自引:5,他引:47  
龙花楼 《地理学报》2006,61(10):1093-1100
土地利用转型是土地利用变化的表现形式之一,也是由IGBP和IHDP联合发起的全球土地研究计划 (GLP) 的重要研究内容。目前土地利用/覆被变化 (LUCC) 研究仍然有待进一步理论化,在学科综合与集成基础上提出的假设对土地变化科学显得尤为重要。土地利用转型研究需要寻求一种综合的方法,来对社会和环境变化的时间尺度和历史背景进行整合。通过分析特定时期内中国农村建房的影响因素及相应的管理政策,在了解中国农村建房发展过程的基础上,提出了中国农村宅基地转型趋势的理论假设:随着社会经济的发展,农村宅基地在增加的建设用地总量中所占比例将由高逐渐降低,直到这一比例趋向于一个固定值。最后运用长江沿线样带农村宅基地转型研究结果验证了该理论假设。  相似文献

长江沿线样带农村宅基地转型   总被引:49,自引:3,他引:46  
龙花楼  李秀彬 《地理学报》2005,60(2):179-188
利用样带这一综合与集成研究的工具,选取无论是在社会经济发展程度还是自然环境要素变化等方面都存在明显梯度的长江沿线样带为研究区,采用横向比较的研究方法,基于一定的理论假设,研究了区内的农村宅基地转型。研究表明:1987~2001年研究区根据土地利用变化的聚集度指数划分的各区段农村宅基地在建设用地增加中所占比例总体上看,从上游至下游,从甘孜-玉树区到泸州-迪庆区、恩施-重庆区、铜陵-宜昌区直至上海-巢湖区,这一比例逐渐降低;长江沿线样带各区段所处的农村宅基地转型阶段与样带内各区段所处的经济发展水平相吻合,基本上验证了此前的理论假设。据此,目前由各省 (区、市) 自行制定农村宅基地标准不利于实现土地的集约利用,国家应根据区域经济发展水平和自然条件的差异分区、分类制定农村宅基地标准。针对研究区目前农村宅基地的发展现状,根据区域农村宅基地转型阶段提出了相应的管理对策。  相似文献

中国山区农村土地利用转型解析   总被引:39,自引:5,他引:34  
山区土地开发及其导致的资源环境问题是农业社会人地关系紧张的体现,工业化、城镇化进程中劳动力转移减轻了山区农村土地的人为扰动,由此驱动土地利用发生转型,引发一系列自然和社会经济效应。按照“土地利用转型—驱动力—效应—响应”的分析框架,剖析中国山区农村土地利用转型的特征和规律,提出山区农村土地整治的响应措施。研究表明:① 山区农村土地利用转型体现出土地利用形态在长期变化过程中的趋势性转折,显性形态转型即由农业社会的耕地扩张和林地收缩演变为城镇化进程中的耕地收缩和林地恢复性增长,隐性形态转型即伴随上述过程发生的土地边际化及生态功能恢复;② 社会经济因素主导山区农村土地利用转型过程,劳动力转移引发土地人为扰动减轻是直接驱动力,务农机会成本上升、恶劣的生存环境等引发劳动力转移的因素是更为根本的驱动力;③ 山区农村土地利用转型降低了土地生态系统脆弱性并提高了其生态安全屏障功能,其社会经济效应应聚焦山区农村发展与农户生计安全层面,并亟需实证研究的支撑;④ 当前山区农村土地利用转型是自然恢复和生态优化的良性过程,有着经济社会发展的必然规律,山区农村土地整治要顺应其土地利用转型规律,目标导向从耕地数量增加转向生态环境保护与社会经济福祉协同提升。  相似文献

区域土地利用转型诊断与调控的分析路径   总被引:1,自引:0,他引:1  
李灿 《地理研究》2021,40(5):1464-1477
土地利用转型正表现为城乡地域系统演变的重要特征,土地利用转型分析的意义在于发现土地利用形态转变指示的土地利用问题。本文尝试解析了区域人地耦合关系下的土地利用形态转型逻辑,系统阐释了区域土地利用转型的诊断分析路径,重点探讨了乡村土地利用转型问题诊断与调控途径。研究指出:① 区域土地利用转型侧重考察土地变化趋势性转折对应的土地利用方式的转变要求,阐释转型分析所指示的土地利用问题及其表现特征,以此找寻转型调控的应对策略。② 应依据尺度和梯度分异方式揭示区域土地利用转型特征,理解不同尺度上转型调控的融合过程,研判区域土地利用转型调控措施。③ 土地服务供给变化是引发乡村土地利用显性形态和隐性形态转型发生错位的关键原因,土地利用显性形态与隐性形态之间的互适关系,则反映了土地利用形态空间关系构成的问题特征。④ 基于乡村地域尺度和梯度分异原则、基于城乡融合发展背景、重构农村土地权利体系和开展国土空间规划是探索乡村土地利用转型调控的四个重要分析路径。⑤ 不同尺度区域土地利用转型认知与转型调控对策的融合仍需要进一步拓展,而激活乡村土地资源要素是调控乡村土地利用转型的关键途径。  相似文献
