基于物元可拓模型的城市生态化水平评价——以江浙两省城市群为例

Evaluation of Urban Ecological Level Based on the Object Meta-Topological Model:Taking City Clusters in Jiangsu and Zhejiang Provinces as An Example

我国传统工业化发展道路"先发展,后治理"的模式已经不适应国情,随着可持续发展战略的实施,生态文明理念深入人心,生态城市建设已成为我国的趋势,如何评价一个城市生态水平建设的高低是首先要考虑的问题。在此背景下,以江浙两省城市群为研究区域,从经济发展、环境保护、社会文明三个角度建立城市生态化水平评价指标体系,探索江浙两省各城市生态化水平变化及影响因子。研究表明:江浙两省城市群整体生态化水平稳步上升,但发展不全面,城市间存在差异且不断扩大;空间格局呈现"三点—外围"结构,地域差距显著;经济和环境是影响城市生态化水平的重要影响因素。

With the implementation of the sustainable development strategy and the popularization of the concept of ecological civilization,ecological city construction has become a trend in China.In this context,city clusters in Jiangsu and Zhejiang Provinces are taken as research areas,and a city ecology level evaluation index system is established from the perspectives of economic development,environmental protection and social civilization to explore the changes and influencing factors of the ecology level of each city in Jiangsu and Zhejiang Provinces.The study shows that:the overall ecologization level of city clusters in Jiangsu and Zhejiang Provinces has been rising steadily but the development is incomplete,and there are differences among cities that are expanding;the spatial pattern shows a "three-point-periphery" structure,with significant regional disparities;the economy and environment are important factors influencing the ecologization level of cities.
