| 摘 要： | 海绵城市规划建设过程中，自然及地质背景条件对低影响开发设施的布设具有重要影响。针对郑州市的1945 km2海绵城市规划区，根据海绵城市建设要达到的蓄水、渗水、净水等功能，分析地表植被、地形坡度、包气带及含水层等海绵特性，构建了基于海绵城市建设的地质适宜性评价体系，并用层次分析法进行评价，结果表明：郑州市海绵城市建设地质适宜性好的区域面积占规划区的3.83%，适宜性较好区域占33.12%，适宜性中等区域占54.05%，适宜性差区域占9.00%；郑州市规划的12个海绵城市重点建设区，有2个覆盖不适宜建设区，分布在龙湖片区西北部和双鹤湖片区；航空港区有建设海绵城市的天然条件，建议在东湖节点周围规划海绵重点建设区。海绵城市建设的地质适宜性评价结果对郑州市海绵城市规划建设有参考意义。

| Abstract: | Natural background and geological conditions have important influence on the layout of low-impact development facilities in the sponge city planning and construction.Aiming at the 1945 km2 sponge city planning area of Zhengzhou city, according to the functions of water storage, seepage and water purification to be achieved by the construction of sponge city, based on the analysis of surface vegetation, topographic slope, vadose zone and aquifer, the geological suitability evaluation system was constructed suitable for the construction of sponge city, and it was evaluated with the analytic hierarchy process.The results show that geologically suitable area accounts for 3.83% or the total planning area, good suitability area for 33.12%, moderately suitable area for 54.05%, and poor fit area for 9.00%.Among the 12 key construction areas of sponge city planned in Zhengzhou, 2 cover unsuitable construction areas, which are distributed in the northwest of Longhu and Shuanghe Lake.There are natural conditions for building sponge city in Air Harbour.It is suggested to plan key sponge construction area around the Donghu ecological node.The evaluation result of geological suitability of sponge city construction is of reference significance to the planning and construction of sponge city in Zhengzhou. |
