长春市包气带土壤入渗与截污性能研讨

The Study on Soil Infiltration and the Performance of Intercepting Pollutants in Changchun Aeration Zone

随着城市规模的发展,面临着诸多的挑战,针对暴雨引发的城市内涝以及地下水环境保护等问题进行了探讨。通过对长春市所处地质环境条件的分析,以包气带土壤为主要研究对象,一方面研究其降水入渗性能,探讨海绵城市发展思路及其对城市内涝的缓解作用。另一方面研究其截污性能,探讨绿色城市建设理念及其对地下水环境的影响程度。据研究结果认为,包气带土壤作为城市建设的根基,同时又是自然界水循环的一道缓冲带与屏障,只有充分认识并合理利用,城市建设才能在绿色、环保的状态下长期、安全发展。

While the city continuously developing in size,it also faces varies of challenges.This article discusses the problems of groundwater environmental protection and urban water logging caused by rainstorm.Through the analysis to the geological environment conditions of Changchun city,and taking the soil of aeration zone as the main research object,on the one hand,it examines the capability of precipitation infiltration,and discusses the development idea of sponge city and its mitigation effect on urban water logging.On the other hand,it researches the pollution interception performance,and explores the concept of green city construction and its influence on groundwater environment.It is concluded that the soil in the aeration zone is the foundation of urban construction,and it is also a buffer zone and a barrier for the water cycle in nature.Only by fully understanding and rationally utilizing,the urban construction can be safely developed with a long term in green and environmentally friendly state.
