【摘要】：大自然的生态系统可为人类提供生态服务,对人类的生产生活起着重要的作用。然而随着城市化和工业化的进程,人类在获取自然服务的同时,也在改变着自然生态系统原有的结构,生态系统的服务功能在一定程度上被削弱,逐渐成为一种稀缺资源,并成为人们关注的热点。针对区域生态服务价值时空分异规律的研究,可为区域的生态规划和土地利用结构调整提供科学依据,对促进区域生态环境的建设和保护有着重要的理论意义和现实意义。本文选取晋城市域为研究区域,首先采用土地利用综合动态度作为划分晋城市域的指标,将其划分为三个区域:城市核心区、城乡交错带和城市外缘区,并分别介绍了三个区域的特征及土地利用状况。然后,对于非建设用地生态服务价值的评估,在谢高地的研究结果的基础上进行区域修正;对于建设用地,采用间接市场法来进行评估。最后,分别对整个研究区域以及三个分区2001年和2010年的生态服务总价值的变化特点、基于各单项生态系统服务和基于各生态系统类型的生态服务价值分异规律作了分析,并采用空间自相关分析方法对研究区生态服务价值的空间集聚规律作了研究。研究表明:晋城市域的生态服务总价值从2001年到2010年呈减少趋势,生态服务价值在各区域分异显著这主要是生态用地在各区域的分布不均衡导致;对生态服务价值影响较大的地类是林地、耕地和建设用地,单项生态服务功能中废物处理和水源涵养功能受城市化的影响退化较为显著;从空间自相关性来看,研究区生态服务价值在空间分布上呈现显著的正相关性,“高-高”区主要集中在城市外缘区,“低-低”区主要集中在城市核心区和城乡交错带,且两个类型区呈进一步扩大趋势,这是由于各区域在城市发展中的功能定位不同,发展方向就不同,土地利用结构就有显著差异,城市核心区注重城市发展,城市外缘区是生态涵养发展区,而城乡交错带处于过渡地带。因此,在城市发展中要制定严格的生态规划,合理规划生态用地,促进城市建设与生态环境统筹协调发展。
[Abstract]:The ecosystem of nature can provide ecological services for human beings and play an important role in the production and life of human beings. However, with the process of urbanization and industrialization, human beings are acquiring natural services at the same time. It is also changing the original structure of the natural ecosystem, the service function of the ecosystem is weakened to a certain extent, and gradually become a scarce resource. The research on the temporal and spatial differentiation of regional ecological service value can provide scientific basis for regional ecological planning and land use structure adjustment. It has important theoretical and practical significance to promote the construction and protection of regional ecological environment. This paper selects Jincheng region as the research area, and firstly uses the comprehensive dynamic degree of land use as the index of dividing Jincheng region. It is divided into three regions: urban core area, urban-rural ecotone and urban outer edge area, and introduces the characteristics and land use status of the three regions respectively. Then, the evaluation of the value of non-construction land ecological services. On the basis of the research results of Xie Highland, the regional correction is carried out; For the construction land, the indirect market method is used to evaluate. Finally, the change characteristics of the total value of ecological services in the whole research area and the three sub-regions on 2001 and 2010 respectively. Based on each individual ecosystem service and each ecosystem type of ecosystem service value differentiation rule was analyzed. Spatial autocorrelation analysis was used to study the spatial agglomeration rule of ecological service value in the study area. The results showed that the total value of ecological service in Jincheng area decreased from 2001 to 2010. The value of ecological services varies significantly in different regions, which is mainly due to the uneven distribution of ecological land in different regions. Woodland, cultivated land and construction land are the most important factors affecting the value of ecological service. The waste disposal and water conservation function of single ecological service function are degraded by urbanization. From the spatial autocorrelation point of view, the value of ecological services in the study area showed a significant positive correlation in the spatial distribution, "high-high" area mainly concentrated in the outer edge of the city. The "low-low" areas are mainly concentrated in the urban core areas and the urban and rural ecotone, and the two types of areas show a trend of further expansion, which is due to the different functional orientation of each region in urban development, and the development direction is different. There are significant differences in land use structure, urban core areas focus on urban development, the outer edge of urban areas is ecological conservation and development areas, while the urban and rural ecotone is in the transition zone. In the course of urban development, strict ecological planning and rational planning of ecological land should be made to promote the coordinated development of urban construction and ecological environment.
