山地城市国土空间水生态规划逻辑框架与实践

Logical Framework and Practice of Territorial Spatial Water Ecological Planning in Mountainous Cities

在总结我国国土空间水生态规划发展进程及山地城市国土空间水生态规划面临的困境基础上,以“五级三类”的国土空间规划体系为切入点,立足“水土—水城—水系”3大空间尺度,确定“屏、源、城、岸、系、流”6大生态维度,提出“全域国土空间—山水城聚合空间—水系网络空间”的山地城市国土空间水生态规划逻辑框架,围绕水土保护、水源涵养、水城相融、水岸协同、水系优化、水质共保6大生态功能,提出相应的规划策略和关键技术,以期为其他山地城市的国土空间水生态规划提供参考。

With a summary of China's territorial spatial water ecological planning progress and its practical dilemmas in mountainous cities,a logical framework of water ecological planning for mountainous city is proposed based on territorial spatial planning with"five levels and three categories".It incorporates 3 spatial scales:water land,water city,water network;defines 6 ecological dimensions:screen,origin,city,bank,system,stream;and consists of 3 levels:whole area space,mountain-water-city integrated space,water network space.Based on the six ecological functions of soil and water protection,water conservation,water city integration,water bank coordination,water system optimization and water quality co-protection,the corresponding planning strategies and key technologies are proposed,in order to provide references for the territorial spatial water ecological planning of other mountain cities.
