- Abstract:
- The construction of drainage system has an important impact on the safety and development of cities and towns. The coefficient of variation method was applied on the comprehensive evaluation of the drainage system in China from 2015 to 2019, and the spatial-temporal distribution characteristics were analyzed to provide a guide of the drainage system. The results show that drainage system of cities and towns in China has generally made a rapid and balanced development, while the development stage varies among regions with significant differences in characteristics. In addition, the disorderly construction of collection and treatment facilities greatly restricts the overall performance of the drainage system. Spatial distribution characteristics of the system development significantly shows that the development level is high in the east and low in the west, and high in the south and low in the north, coinciding with the spatial distribution of regional economic levels.
