Abstract

With the development of cities, environmental andecological systems have been affected under certain damage andthe change of water circulation system. In this paper, mainly twokinds of low impact development (LID) facilities are studied:bio-retention and cistern system. From their own characteristics,they were analyzed including application efficiency andlandscape effect. The research shows that the landscape effect onbio-retention is better, and its effect on flood control isparticularly prominent in the process of small-scale rainfall.Cistern system has relatively low manufacturing cost. Its settingis flexible, more runoff can be detained. And it has prominentand stable effect on water balance. These two facilities are fitable choices in urban planning and construction.
