辽宁省低碳经济发展水平评价

构建包含经济系统、能源系统、碳排放系统、技术投入系统和环境系统5个准则层及23个指标的低碳经济发展水平评价体系,基于可变模糊识别模型,分析评价辽宁省低碳经济发展水平。结果显示:辽宁省低碳经济发展水平由2004年的2.87提升到2014年的3.01,由中碳偏高水平提升到中碳发展水平。沈阳、大连、丹东、锦州、营口和葫芦岛的低碳经济发展水平较高;鞍山、抚顺、本溪、盘锦、辽阳及铁岭的低碳经济发展水平较低。在此基础上,运用SBM模型测算辽宁省各市的碳排放效率,其结果与低碳经济发展水平评价值有较大关联。     

Conservation of the Important Agricultural Heritage Systems in the Economically Developed Area：Experiences,Problems and Solutions—A Case Study of Zhejiang Province

Zhejiang Province, located in the Yangtze River Delta region, is representative of China's economically developed areas. It enjoys superior natural conditions and a long history of agriculture, and is a comprehensive agricultural area with integrated development of agriculture, forestry, animal husbandry and fishery. It has nurtured the farming culture represented by Hemudu culture and Liangzhu culture, which have given rise to numerous precious Agricultural Heritage Systems. At present, Zhejiang Province has three of the world’s Globally Important Agricultural Heritage Systems (GIAHS) and 12 China Nationally Important Agricultural Heritage Systems (China-NIAHS), so it not only has the largest number of heritages in China, but it has also attained remarkable achievements in heritage conservation. Taking Zhejiang Province as an example in combination with the rural revitalization strategy, this paper summarizes the achievements in the protection of Important Agricultural Heritage Systems (IAHS) in Zhejiang Province during the past 15 years from the aspects of increasing farmers’ income, cultural Inheritance and industrial upgrading, as well as the conservation experiences in government promotion, community initiative, enterprise participation, technology driving and social linkage. Further, in view of the problems that exist in the current heritage protection,such as imperfect management of heritage sites, low participation of community residents, lack of special protection funds, and imperfect provincial management system,the following countermeasures and suggestions are put forward: (1) Improve the management mechanism for the conservation and development of Agricultural Heritage Systems; (2) Develop regional public branding of agricultural products in Agricultural Heritage System sites; (3) Increase the Agricultural Heritage System science education as well as cultural and creative product development; (4) Carry out the evaluation and recognition of IAHS at the provincial level; and (5) Provide substantial support and input to the conservation and utilization of IAHS. This study can provide some guidance for the conservation of IAHS in Zhejiang Province and it provides important reference for IAHS in the economically developed areas in China.     

河北省主要农作物生产时空格局变化特征及安全评价

阐述主要粮食作物的时空格局变化特征,对中国粮食安全决策意义重大。基于河北省县市近15 a (2001~2015年）的农业数据资料,采用分段线性趋势以及生产指标-产量波动系数来分析河北省主要粮食作物的时空变化特征,并对河北省粮食作物进行安全评价。结果表明：从产量与播种面积来看,近15 a河北省主要粮食作物变化趋势经历了由波动减少到稳步增长2个阶段,且变化趋势显著;从空间格局变化来看,大致呈由南向北逐渐递减的规律分布,其中不同农作物分布规律各有差异;从粮食安全方面来看,河北省70%以上年份粮食波动系数均超过中国粮食安全平均水平,粮食波动系数较高,粮食安全风险较大;但从人均粮食产量来看,安全程度相对比较乐观,粮食安全状况渐趋于平稳。研究可为河北省粮食生产时空布局的优化、结构调整与社会经济协调发展提供依据。     

基于改进当量的甘肃省耕地生态系统服务价值及其与区域经济发展的空间关系研究

为量化分析耕地生态系统服务价值及其与区域经济发展的空间关系,采用改进的耕地当量因子,对甘肃省2014年耕地生态系统服务价值进行定量化研究,并采用双变量空间自相关探讨其与区域经济发展在空间上的关联关系。结果表明：（1）在GPP修正的基础上估算得到的甘肃省2014年耕地生态系统服务价值为4.96×10¹¹元,其中水资源供给功能的价值为负,食物生产功能的生态系统服务价值相对较高,美学景观功能的生态系统服务价值最低。（2）双变量空间自相关显示人均国内生产总值与耕地生态系统服务价值在空间上存在显著的负相关关系,Moran’s I指数为-0.252 3。局部双变量空间自相关LISA图也显示低-高聚集区主要分布在经济发展相对落后、具有明显生态优势的东南部地区;而高-低聚集区则主要分布在经济高速发展,生态环境相对恶劣的西北部地区。研究结果可为甘肃省生态环境管护与区域经济发展提供决策参考,为实现经济增长与生态保护统筹协调发展提供参考依据。     

江南丘陵地区乡村聚落地域分异特征研究——以湖南省为例

以江南丘陵湖南地区为研究对象,通过对18个抽样村进行实地走访与问卷调查,从乡村聚落的居住条件、居住设施和乡村居民的生产生活形态等方面,探讨江南丘陵湖南地区乡村聚落空间地域分异特征与规律。研究表明：乡村聚落研究是江南丘陵地区乡村聚落空间布局优化与调控的基础。由于地域范围广泛,区域内的资源禀赋与地域组合、经济发展基础、文化传统等条件差异悬殊,因此江南丘陵湖南地区乡村聚落发展的地域分异规律较为明显,在聚落空间格局（规模、密度、形态）、居住条件（住房面积、住房结构、建筑特色）、居住设施（道路、饮水安全、网络电视开通率等基础与公共服务设施）和生产生活形态等方面呈现出较为显著的盆地-丘陵-低山区、发达-欠发达-落后、近郊-远郊-偏远等地貌、经济、区位梯度差异。     

吉林省人口老龄化时空分异特征及成因

本文基于地理信息软件ArcGIS 10.1,选取老年人口系数为人口老龄化指标,运用人口重心模型、空间自相关和半变异函数等分析方法,对吉林省第四次、第五次、第六次人口普查数据进行分析,探讨1990-2010年吉林省人口老龄化时空分异特征,并采用多元线性回归方法解释其形成原因。研究结果表明：①吉林省各县市人口老龄化差异明显,进程加快,重心由西北向东南方向移动,但移动速度减缓;②吉林省人口老龄化存在正的空间自相关性,在空间的集聚呈现先弱后强的变化趋势;③人口老龄化高—高区向东部集聚,低—低区向西部集聚的趋势比较明显;④总体上吉林省人口老龄化空间的结构化分异较为明显,随机性因子引起的空间异质性程度较弱,人口老龄化的空间差异主要体现在东—西方向上;⑤出生率始终是影响吉林省人口老龄化的主要因素,迁出率对人口老龄化发展起关键作用,人均GDP年对人口老龄化呈负相关,城市化率对人口老龄化的推动作用愈发显著。     

湖南省传统聚落景观基因组图谱的空间形态与结构特征

传统聚落保有显著的价值,深入开展相关研究有利于促进经济社会的可持续发展和新型城镇化战略的实施。结合传统聚落景观基因组图谱,本文探讨了湖南省传统聚落景观的空间形态与结构特征。首先,根据传统聚落景观基因组的空间排列特征将湖南省传统聚落的空间形态归结为向心圆环式、扇形扩张式、多向扩张式、条带式、离散式和组团式等5种基本类型,并进一步归纳了各种形态类型的特征。其次,运用空间句法理论,通过构建传统聚落景观基因组的空间轴线模型,系统地剖析了湖南省传统聚落景观的空间结构特征,发现湖南省传统聚落的空间结构具有对称和平行等鲜明的几何特征,存在着“界域”和“街—巷—码头”等典型结构,还具有典型的风水意象特征。因此,结合传统聚落景观基因组图谱从地理学的视角揭示传统聚落的地学特征,有利于完善传统聚落景观基因理论,深化对传统聚落的认识,促进相关保护工作。     

Review of Research on Characteristic Tourism Resources Exploitation in Sichuan Province

With the rapid development of tourism in China’s Sichuan Province, research on the development of tourism resources in Sichuan has drawn increasing attention from the academic community. This article briefly reviews three aspects of the literature on the development of tourism resources in Sichuan: a survey and evaluation of Sichuan tourism resources, the development of tourism resources that are characteristic of Sichuan, and the development of tourism resources in Sichuan. The current situation of the development of Sichuan’s tourism resources was considered and seven factors were evaluated: tourism in ancient towns, tourism in ethnic areas, folk tourism, eco-tourism, rural tourism, red tourism and earthquake tourism. The article also addresses the development of tourism resources in Sichuan. Most existing studies of the development of tourism resources in Sichuan are based on applied research; they are deficient in both scope and depth, and cannot serve as a basis for the development of theory. Few studies have focused on market demand for tourism, the establishment of management mechanisms or the development of regional cooperation. In the future, tourism theories like space theory for space competition, RMP analysis theory, cultural ecology theory, and other tourism theories should be closely integrated with the development of tourism resources in Sichuan. Whether the subject matter is sustainable development, market demand, management mechanism construction, regional collaborative development or other concerns, this will allow more systematic, in-depth studies that produce improved results that are both pertinent and realistic.     

Analysis of Spatial Mismatch of Tourism Development in Guangdong Province

The spatial mismatch situation of tourism development in Guangdong Province is analyzed by gravity model and two-dimensional matrix based on the spatial mismatch hypothesis, and the results are visualized using ArcGIS software. This study finds that varying degrees of spatial mismatch exist between the level of tourism development, abundance of tourism resources and accessibility of tourism locations in the 21 cities in Guangdong Province. The gravity centers for tourism economy, tourism resources and tourism location are (113.55° E, 23.00° N), (113.69° E, 23.21° N) and (113.74° E, 22.86° N), respectively. According to the two-dimensional combinatorial matrices, synchronous development is shown in 10 prefecture-level cities for the tourism revenue-resource abundance combination, whereas it is shown in seven prefecture-level cities for the tourism revenue-tourism location combination. Guangzhou and Shenzhen are synchronous-double high zones for both combinations, while Foshan, Qingyuan, Yangjiang, Zhongshan and Jieyang are deviating-negative mismatch zones for both combinations. Furthermore, the vast majority of prefecture-level cities within the province currently present mismatching trends in tourism development. Based on the analysis results, corresponding countermeasures and suggestions are put forward taking into account the actual situation and opportunities for further tourism development in various prefecture-level cities.
