摘要:探索生态系统服务与城市化的空间交互关系为城市发展和保护提供新的视角。以长株潭城市群为例，以其2015年的土地利用、经济社会等数据为基础，利用格网分析和空间自相关模型解析城市化与生态系统服务的空间交互规律。结果表明：（1）长株潭城市群城市化水平空间分布区域差异性显著，城市化水平由高到低依次为城市化地区、正在城市化地区和生态绿心保护区，表现出从城市化地区向周边地区依次递减的态势。（2）受城市化水平和土地利用变化等影响，生态系统服务空间分布具有明显的差异性，并呈现出"中心-外围"逐步升高的趋势。（3）长株潭城市群城市化与各项生态系统服务之间呈显著负相关，由于驱动机制的不同，城市化地区、正在城市化地区和生态绿心保护区的城市化对生态系统服务的影响存在显著差异。（4）长株潭城市群的各项生态系统服务与城市化之间存在四种空间相关类型。高高集聚区和低低集聚区零散分布在整个研究区域，面积较小；高低集聚区分布在湘潭县西南部、株洲县东南部，面积较大；低高集聚区分布集中在城市化地区，呈现块状分布，面积较大。



Abstract:Exploring the spatial interaction between Ecosystem Services (ESs) and urbanisation can provide a new perspective for urban development and protection. Taking the Changsha-Zhuzhou-Xiangtan (CZT) urban agglomeration as a case study, with reference to its land use and social economy in 2015, this paper employs grid analysis and a spatial autocorrelation model to analyse the spatial relationships between urbanisation and ESs. The results show that:(1) The spatial distribution of the levels of urbanisation are characterised by evident regional differences within the CZT urban agglomeration, with the level of urbanisation decreasing from urbanised areas to urbanising areas and to ecological conservation areas. (2) The spatial distribution pattern of ESs, influenced by the level of urbanisation and land use change, showed a obvious difference, with the values associated to ESs gradually increasing from the urban centres to the peripheries. (3) Urbanisation and individual ESs show significant negative correlation. Due to the different driving mechanisms, urbanisation in urbanised areas, urbanising areas, and ecological conservation areas had significicantly different impacts on the individual ESs. (4) Four spatial correlation types between individual ESs and urbanisation levels in the CZT urban agglomeration are identified. High-High areas and Low-Low areas are scattered throughout the study area, but cover only a small portion of it; High-Low areas are concentrated in the southwest of Xiangtan County and southeast of Zhuzhou County, and cover a larger proportion of the study area; Low-High areas are concentrated in the cities within the urban agglomeration, and as such they are widespread and cover large areas.
