Abstract The problem of rural water ecological environment is becoming growingly prominent, and its ecological management is of great significance From sponge cities to sponge villages, it is an effective way to use the low-impact development (I ID) technology to solve rural water ecological environment problems. Through the investigation and analysis of the hydrology, soil, runoff vegetation and other factors in the Wei River wetland of Fengxi New City of Xixian New Area, this study attempts to construct a TJD route suitable for managing the rural water ecological environment in the northwest, so as to provide a reference for the construction of green infrastructure and sponge cities of rural areas in the northwest

In October 2014, the Ministry of Housing and Urban-Rural Development of the People's Republic of China issued the Technical Guide for Sponge City Construction-Establishment of the Low-Impact Development (LID) Stormwater System (Trial). In October 2015, the General Office of the State Council of China issued the Guiding Opinions on Promoting the Construction of Sponge City, requiring the sponge city pilot area to comprehensively utilize "infiltration, stagnation, storage, purification, use, and drainage", thereby absorbing and utilizing 70% of the precipitation on the spot. On February 4, 2018, China's State Council promulgated Document No. 1 of 2018, namely, Opinions of the Central Committee of the Communist Party of China on Implementing the Rural Revitalization Strategy. The 18th National Congress Report and 19th National Congress of the Communist Party of China have also clearly stated the relevant requirements for rural ecological civilization construction. Implementing the rural revitalization strategy is a key measure for building a beautiful China, and rural ecological civilization construction is an important part of it. Therefore, the research on the LTD of the water ecological environment of the Wei River wetland in Fengxi New City of Xixian New Area in Shaanxi Province is of great value to the surrounding water ecological environment improvement, green facility planning and sustainable development
Based on the GIS and on-the-spot investigation, this paper integrates the concept of low-impact development with the ecological wetland landscape based on the full analysis and demonstration of the current natural conditions, and treats the stormwater through a...
