Building a sponge city requires patience to fight a protracted war.

In recent years, waterlogging and "looking at the sea in the city" have become endless troubles in the rapid expansion of many cities. The reason is that some unscientific planning and construction have disturbed the natural water cycle. The sponge city is a relatively advanced concept of urban construction. In October last year, the General Office of the State Council issued the "Guiding Opinions on Promoting the Construction of Sponge Cities", proposing that through the construction of sponge cities, comprehensive measures such as "infiltration, stagnation, storage, purification, use, and drainage" should be adopted to minimize the impact of urban development and construction. The impact of the ecological environment will be absorbed and utilized on the spot.
Rome was not built in a day, and sponge cities cannot be built overnight. According to the guidance of the State Council, the time for the assessment of pilot cities is 5 to 10 years. From this point of view, it is too early to discuss success or failure. Of course, such questioning is not meaningless. The public's emotional expression of sponge city also truly reflects the problems existing in the construction process of some places. For example, some places do not really understand the connotation of sponge city, thinking that simply expanding pipelines, paving permeable floor tiles or placing water storage tanks are building sponge city, while ecological protection and restoration have not received due attention. Even in some places, while vigorously laying pipe networks, one side is reducing the natural water surface, which violates the original intention of sponge city construction.
Frozen three feet is not a day's cold. Not only sponge cities, many environmental problems are not formed overnight, and the governance of these problems cannot be achieved overnight. It is necessary to have the patience to fight a protracted war. For example, soil pollution control, air pollution control, etc., are all systematic projects with long cycles, high costs, and slow results. It is impossible to expect a pat on the head to cure such problems immediately. Since it is a system engineering, we should use the spirit of science, adopt a systematic method, peel off the cocoon, step by step, and make solid progress for a long time.
