江苏省生态环境时空格局演变研究

Spatial-Temporal Pattern Evolution of Ecological Environment Research in Jiangsu Province

城市生态环境的优良程度关系到居民的生活质量、区域和谐发展程度。文章首先对江苏13个市的生态环境水平和产业结构进行综合评价,并运用空间统计和标准差椭圆模型对江苏的生态环境水平进行空间分布格局和时空演变特征分析;最后用耦合协调度模型测度江苏生态环境水平与产业结构发展的协调程度。由模型结果分析可知:江苏整体的生态环境水平差异在发展过程中逐渐缩小,但内部水平的集聚分布呈苏南、苏北两极分化;苏北的生态建设有一定成效;各市的协调程度逐步趋于协调;部分地区的经济发展方式需调整,如宿迁、常州。

The degree of cities ecological environment is related to the quality of life of the residents and the degree of the harmonious development of the region.With the rapid economic development of Jiangsu Province,ecological environment protection has become a challenge.In this paper,the ecological environment level and industrial structure of 13 cities in Jiangsu Province are comprehensively evaluated at first.The spatial and temporal evolution characteristics of the ecological environment level in Jiangsu Province are analyzed by using spatial statistics and standard deviation ellipse model.Finally,the coupling coordination degree model is used to measure the coordination degree between the level of ecological environment and the development of industrial structure in Jiangsu Province.It can be seen from the analysis of model results:the overall level difference of ecological environment in Jiangsu Province is gradually reduced in the process of development,but the concentration distribution of internal level shows the polarization of southern Jiangsu and northern Jiangsu.The ecological construction in northern Jiangsu has achieved certain results.The coordination degree of each city tends to coordinate in the development.The pattern of economic development in some regions needs to be adjusted,such as Suqian and Changzhou.
