海绵城市水文评价指标研究——以西北地区为例

摘要

To improve the pertinence of the construction of Sponge City in different regions,this paper analyzes the climate and geological conditions of northwestern China as well as the main hydrological problems with cities. In combination with the characteristics of northwestern China and the existing assessment indicators of sponge cities both at home and abroad,establishes the hydrological assessment indicators for sponge city in this region in terms of water security,water ecology,water environment and water resources. Then,validates the rationality of assessment indicators by structural equation model,meanwhile,analyzes the importance of each indicator.%为了提高海绵城市建设在不同地区的针对性,以西北地区为例,对气候、地质条件以及城市面临的主要水问题进行分析.结合国内外已有的海绵城市评价指标和西北地区的特点,从水安全、水生态、水环境和水资源4个方面构建该地区的海绵城市水文评价指标.然后采用结构方程模型验证评价指标的合理性,分析各指标的重要性程度.
