城市环境对城市可持续发展的制约关系分析

在中国城市发展指标体系的基础上,以建设生态城市、实现可持续发展为目标,50个城市为对象,分析了城市环境质量与城市可持续发展体系中各状态要素之间的相关性.结果表明:在50个城市可持续发展能力指数中,以环境质量为控制要素的占72%,这一要素与城市可持续发展指数的相关性R2=0.883 9;城市环境质量水平的高低与基础实力、城市竞争力和管理能力等支持系统均有密切关系,这些支持系统水平的高低决定了城市可持续发展能力,即城市环境质量是制约城市可持续发展能力的关键要素.

Restraint of urban environment on urban sustainable development

Aiming at the construction of eco-cities and realization of sustainable development,an analysis was made on the correlations between urban environmental quality and each key factor in urban sustainable development system for 50 cities in China based on the index system for urban development.The result shows that 72% of the 50 cities are environmental quality dominated in their sustainable development,and that the correlation coefficient(R~2) is up to 0.883?9.According to the analysis,the level of urban environmental quality is closely related to the urban supporting systems,such as the urban infrastructure level and competitive and management power of cities.The level of supporting systems dominates the capacity of urban sustainable development,i.e.the quality of urban environment is the key factor restricting the capacity of urban sustainable development.
