Reporters recently learned from the office of the leading group of sponge city construction in Kunming that this year, Kunming plans to invest 5.755 billion yuan to implement 340 sponge city construction projects, which will maximize the retention of rainwater and make use of it. At the same time, those who do not advance their work effectively and act slowly will be held accountable.

On the one hand, there is water shortage, on the other hand, a large amount of rainwater flows away in the flood season. This situation will gradually change in Kunming. According to the decomposition of the objectives and tasks of the sponge city construction in Kunming, this year, the districts, management committees and Ningbo strive to complete the construction area of the sponge city of 19.15 square kilometers. Among them, Wuhua District 1.78 square kilometers, Panlong District 2.14 square kilometers, Guandu District 3.12 square kilometers, Xishan District 1.74 square kilometers, Chenggong District 1.92 square kilometers, Jinning District 2.95 square kilometers, Anning City 1.58 square kilometers, Jingkai District 1.91 square kilometers, resort area 1.09 square kilometers, High-tech Zone 0.54 square kilometers, Airport Economic Zone 0.36 square kilometers.

Building sponge cities with natural accumulation, natural infiltration and natural purification is an important measure to promote the transformation of urban planning and construction concept, alleviate the shortage of water resources, reduce the pollution of urban rainwater runoff, effectively reduce the pollution load of urban non-point sources into lakes, effectively reduce urban floods and drainage pressure, improve and repair the water ecological environment of Dianchi Basin, and implement the construction of ecological civilization. Measure. This year, Kunming plans to implement 340 sponge city construction projects. Among them, there are 133 projects of sponge-type urban buildings and districts, 140 projects of sponge-type urban roads and squares, 17 projects of sponge-type urban parks and green spaces, 8 projects of ecological wetlands, 23 projects of drainage and reclaimed water network, 6 projects of waterlogging and drainage dredging, 12 projects of flood control and 1 project of ecological restoration of vegetation in Mianshan of Dianchi basin. The estimated total investment is about 57.55. Billion yuan. It is understood that the responsible units and persons will be held accountable if the work is not propelled properly and the action is slow. Especially those who fail to strictly implement the technical specifications and requirements of sponge city construction for new construction projects will be held responsible.

It is worth noting that in order to control rainwater runoff, Kunming will also complete afforestation and young forest tending of 10,000 mu in the area of ecological restoration of vegetation in the Mianshan Mountains of Dianchi Basin. Among them, Wuhua District completed 3000 mu, Panlong District completed 2000 mu, Xishan District completed 2000 mu, Jinning District completed 3000 mu.

The purpose of sponge city construction is to increase rainwater collection and utilization. According to the "Kunming Sponge City Construction Work Program", by 2020, more than 20% of the built-up area will meet the requirements of the Sponge City Construction Standard, and urban non-point source pollution will be controlled to a certain extent; by 2030, more than 80% of the built-up area will meet the requirements of the Sponge City Construction Standard, urban non-point source pollution will be effectively controlled, and the water environment quality of the river basin will be significantly improved.

It is understood that after years of efforts, 211 sponge-type buildings and districts, 65 sponge-type roads, 51 sponge-type parks (green spaces), 17 rain and sewage reservoirs and 54,000 Mu lakeside ecological wetland (forest belt) have been built in Kunming, forming a large number of demonstration projects.

Hongyi Machinery assists the construction of sponge city, and has developed the permeable brick equipment of "sponge city" for many years. Now, there are many production cases in cities, which have won unanimous praise. Welcome to consult and visit.
