摘要
自然环境及地质条件对海绵城市建设影响重大,以咸宁市咸安区自然地质条件为基础,根据海绵城市建设的功能要求,分析含水层、包气带、地面条件等方面的海绵特性,建立咸安区基于海绵城市建设地质条件适宜性评价体系,采用层级分析法进行评价。评价结果显示,极适宜区、较适宜区、一般适宜区、较不适宜区及不适宜区的面积占比分别为8%、20.1%、14.9%、23.9%和33.1%。评价结果对鄂东南地区海绵城市规划建设具有参考意义。
Natural environment and geological conditions have a great influence on the construction of sponge city.Based on the natural geological conditions of Xian an District of Xianning City,this paper analyzes the sponge characteristics of aquifer,vadose zone and ground according to the functional requirements of sponge city construction,and establishes the suitability evaluation system of geological conditions based on sponge city construction in Xian an District,and evaluates it by analytic hierarchy process.The evaluation results show that the proportion of extremely suitable area,more suitable area,general suitable area,less suitable area and unsuitable area is 8%,20.1%,14.9%,23.9%and 33.1%,respectively.The evaluation results have reference significance for the planning and construction of sponge city in southeastern Hubei.
