我的家乡衡水市属于中重度缺水城市,而自然降水多集中在夏季,如何充分利用宝贵的雨水资源成为一个新亮点。调查走访发现,目前我市尚无住宅小区进行雨水收集利用。社区占地面积大,地面雨水径流流量也大,如果能充分利用自然降水不但可以绿化、美化环境又可以缓解用水紧张,还能使雨水重新流入土壤,保护水循环。因此,我进行了城市社区雨水回收利用的科学探究。 My hometown of Hengshui belongs to moderately and severely water-scarsed cities, and most of the natural precipitation is concentrated in summer. How to make full use of precious rainwater resources has become a new bright spot. Survey visits found that at present there is no residential area in our city for rainwater collection and utilization. Community covers an area of ​​large, ground rainfall runoff is also large, if we can make full use of natural precipitation can not only green, beautify the environment and can ease the water stress, but also to re-flow of rain into the soil to protect the water cycle. Therefore, I conducted a scientific inquiry into the recycling of rainwater in urban communities.
