-
A city in the northwest is located in the gully region of the Loess Plateau, where soil erosion is severe ， and the construction of sponge city can solve problems such as water and soil loss, urban flooding, water environmental pollution, drought and water shortage. Taking the sponge city renovation of the school as an example, the design ideas and technical routes of the school sponge city reconstruction project in the cold region of the Loess Plateau were introduced. Through the systematic plan, taking the volume capture ratio of annual rainfall as the main goal, taking pollution control and rainwater resource utilization into account, this paper analyzed the transformation of school sponge city from the aspects of source control, process control, end treatment, rainwater reuse and project benefit. Combining technical measures such as “infiltration”, “retention”, “storage”, “purification”, “use” and “drainage”, it has achieved the goal of 81% volume capture ratio of annual rainfall, which could provide reference for the use of low impact development technology to build school sponge city in the Loess Plateau and cold collapsible loess area in northwest China.
