In the construction of sponge city, we insist on being problem-oriented for the current built-up area, and focus on solving the existing problems through the transformation of sponge city.

In the construction of the sponge city, in order to achieve a good landscape effect on the municipal roads, greening around the roads has become an important part of improving the road landscape and improving the surrounding environment of the roads. However, due to terrain constraints or landscape needs, there will inevitably be some slopes in the green belt, and the precipitation or irrigation water on these slopes can easily flow down the slope, resulting in rapid runoff loss. In this way, the plants planted on the sloping land will wither or even die due to lack of effective irrigation, which will greatly affect the landscape effect of the municipal road, and it will also increase the management and maintenance expenses, which is not conducive to the use of rainwater resources. In addition, due to the increase of surface runoff, the overflow pressure of the municipal rainwater pipeline will be increased, resulting in water accumulation on the road after heavy rain.
