Analysis and research on the regional adaptability of sponge city

Abstract

Based on the three values of per capita water resources, precipitation, and sewage and wastewater discharge, our country's cities are divided into three types: water resource shortage, water quality shortage, and water pollution and water-logging risk cities. Comparing these three kinds of sponge cities, combining with the regional differences of my country's first-tier, new first-tier and second-tier cities, determine the types of sponge cities in my country's important cities. In view of the different water problems of the three types of cities, the regional adaptive construction plan of sponge cities is summarized.
