Abstract
With the development of economy and the change of life-style, non-point source pollution has become one of the key points of ecological environment regulation. In order to research how to control non-point source pollution according to the specific situation of towns, this paper selected Hongshi Town, Laohu Town and Xinxing Town of Tongchuan City in Shaanxi Province as the representative residential areas for analysis. In this paper, the present situation of non-point source pollution in the three towns were analyzed, and the regulation measures were put forward according to the specific situation of each town, such as laying sewage pipes or rain trenches, adding public toilets and garbage collection points. Through the comprehensive treatment of non-point source pollution, the ecological security of cities and towns has been guaranteed, the ecological balance of regions has been maintained, and a benign ecological security pattern is forming.
