摘要：城市是人类活动集中的场所，城市的发展对于区域生态健康具有重要意义已经成为一个不争的事实，而城市生态健康空间分布对城市及地区的发展更加有着不可忽略的影响。本文首先采用层次分析法，从组织结构、活力、恢复力、城市服务功能四个方面建立相对完整的城市生态健康评价指标体系；然后以江苏省13个地级市为例，根据指标体系计算出2010年和2015年的生态健康指数；最后运用GIS空间分析能力，探讨分析江苏省城市生态健康时空分布格局情况。研究结果表明：5年来江苏省城市生态健康空间分布格局相对稳定，以盐城为中心向苏南苏北递减的规律基本没变，但是在苏南和苏北地区城市生态健康状况得到改善的同时，苏中地区却出现了恶化趋势，值得引起关注。91095

Abstract ： City is the place where human activities are concentrated。 It has become an indisputable fact that the development of city is essential to the healthy development of the earth。 And healthy space distribution of city ecology has an effect, which can not be ignored, on the development of cities and regions。 First of all, this thesis uses analytic hierarchy process, abbreviated as AHP, to establish a relatively complete urban ecological health assessment indicators system from the four aspects of organizational structure, vitality, resilience, urban

service functions; then based on a case study of 13 prefecture-level cities in Jiangsu Province, this thesis calculates ecological health index in 2010 and 2015 according  to indicators system and relates it to ArcGIS。 Finally, the spatial and temporal distribution pattern of urban ecological health in Jiangsu Province was analyzed by using GIS spatial analysis ability。 The results show that the spatial distribution pattern of urban ecological health in Jiangsu Province has been relatively stable in the past five years, and the descending law taking Yancheng as the center to the south part and the north part of Jiangsu Province is basically unchanged。 However, as the urban ecological health status of the north part and the south part of Jiangsu Province has been improved at the same time, mid-jiangsu region has showed a trend of deterioration, which deserves great attention。

Keywords ： Urban ecological health, spatial distribution pattern, analytic hierarchy process, spatial analysis
