基于耗散结构理论的上海城乡绿地系统空间演化特征

Spatial Evolution Characteristics of Urban-rural Green Space System in Shanghai Based on Dissipative structure Theory

文章选取上海2000—2015年的城乡绿地系统空间相关数据,通过耗散结构理论的熵值分析法,首先分析了上海城市建设用地多样性在全国处于中等的研究背景,其次总结了上海城乡绿地系统的3项空间演化特征,即游憩型绿地的开放性增强、绿地功能类型多样性增加、生态因子具有非线性作用,最后提出风景游憩绿地需提升综合品质,生态保育绿地应实施自然再生等优化策略。

Under the goal of ecological restoration,the study of urban-rural green space system based on dissipative structure theory can provide the theoretical support and practical guidance for the essential regularity of space-time evolution.Based on the spatial data of urban-rural green space system in Shanghai from 2000 to 2015,and through the entropy analysis method of dissipative structure theory,this paper firstly analyzed the research background that the diversity of urban construction land in Shanghai is in the middle level of whole country.Secondly,it summarized three spatial evolution characteristics of urban-rural green space system in Shanghai:the openness of recreational green space is enhanced,the diversity of green space function types is increased,and the ecological factors have a non-linear effect.Finally,it is proposed that recreation green space should improve its comprehensive quality and ecological green space should implement natural regeneration and other optimization strategies.
