Abstract:Zhangye has an ancient reputation of "half a city reed half a city tower, a lake with flowers racing Jiangnan". Surrounded by a moat and connected by ponds and ponds, it is clear that its rich water system has created a good urban water ecology and wetland landscape. However, with the rapid development of the city, the water ecological environment in the urban area has been destroyed to a certain extent, especially in the southeast of the city. The present water system is mostly blocked by urban construction, and the water ecological environment is relatively fragile. Based on the analysis of the present situation and the study of the overall planning of Zhangye, the planning ideas of using the agricultural drainage of irrigation canal as the water source and constructing the water system around the city along the Third Ring Road are proposed. And through five strategies of the "ecological meltwater, dam retaining water, excavating catchment, scientific green water and waterways connection", the planning vision of "water moistening Zhangye, cultural city" is finally realized. Its effect can provide the reference for the water system planning of the other cities.
