长江经济带内陆节点城市生态系统状态评价研究 ——以长江中游城市带为例
Study on evaluation of ecological system state of inland key cities of Yangtze River Economic Belt:case of cities in midstream of Yangtze River
摘要
Abstract
In the implementation of the Yangtze River Economic Belt Strategy, the open and development of inland cities caused great pressure on the urban ecological system. We carry out the comprehensive evaluation of ecological system pressure, state and response in 10 key cities of middle Yangtze River Basin. It shows that the industrial wastewater, waste gas and solid waste discharge are the main sources of the pressure on urban ecological system;the ecosystem health status of most cities in the urban belt of middle Yangtze River Basin is below the well level;strengthening the pollution treatment project investment, impro-ving the forest coverage and the green space area of the city plays an important role in reducing the pressure on urban ecological system.关键词
