In the Hohhot Silk Road Theme Park, the yellow and blue colorful pavement is particularly eye-catching. This permeable pavement is one of the important signs of the construction of the sponge city. The permeable concrete pavement has water permeability, which can quickly eliminate the water accumulation in the road and the square when it rains. When the rain is collected, it can reduce the burden of urban drainage equipment, prevent river overflow and water pollution, and protect the urban water balance.

A sponge city means that a city can be like a sponge and have good "elasticity" in adapting to environmental changes and responding to natural disasters. It absorbs, stores, seeps, and clears water when it rains, and releases and stores the stored water when needed. . The focus of sponge city construction is the construction of sponge city roads and sponge city roads.

"The construction of the sponge city makes the city even more livable! Even after heavy rain, when we walk in the Silk Road Park, the shoes will not get wet!" Wei Lihua, a citizen who was playing with his grandson, was impressed.

In 2015, the General Office of the State Council issued the "Guidelines on Promoting the Construction of Sponge City". In 2016, in response to the call of the Ministry of Housing and Urban-Rural Development, the autonomous region government issued the "Implementation Opinions on Promoting the Construction of Sponge City" and invited a number of well-known domestic experts to come to our district to help carry out the technical review of the sponge city's special planning. As of June 2017, nine cities in the region including Hohhot, Baotou, and Bayannaoer have completed the drafting of a special sponge city planning plan.

Hohhot promotes the construction of sponge cities by doing "subtraction". After "reducing the burden" on the traditional drainage system, the city has adopted the methods of "seepage, stagnation, storage, net, use, and drainage" to minimize the impact of urban development and construction on the ecological environment. Up to now, 16 square kilometers of the city's built-up area has reached the sponge city construction requirements.

Hohhot has continuously explored the construction of underground pipe gallery drainage systems, gradually replacing traditional gray equipment such as direct buried pipeline networks. With a total investment of 975 million yuan and a total length of 4.74 kilometers, the Lilac Road induction pipe gallery was started in May 2014 and completed in early August 2016. It has now been included in power pipelines, water pipes, straight drinking water pipes and communication optical cables. According to the plan, the construction length of Hohhot's urban underground induction duct corridor will reach 264.04 kilometers by 2030.

The magnetic field effect of sponge city construction is forming: Baotou city plan for 2017, 35 new sponge city construction projects, including parks, roads, campuses and other aspects; Tongliao City has now completed 120,000 square meters of green belt, 16,000 park oasis Square meters, with an investment of 18.4 million yuan.

Fu Dongmei, a researcher at the Autonomous Region Development Research Center, pointed out that promoting the construction of sponge cities is an important part of steadily increasing, adjusting the structure, promoting change, and benefiting the people's livelihood. It is an important action to implement the construction of ecological civilization and an important method for the green development of urbanization. To build a sponge city, it is necessary to adapt to the nature and build a natural accumulation, natural impregnation, and natural purification of the sponge city according to the center's proposal. It is necessary to pay attention to the construction of the underground pipe network, but also to consciously reduce the development intensity, and preserve and recover the appropriate share of ecological space.

Facing the uneven distribution of urban oasis in our region, the lack of oasis in the old urban area, and the impact on rainwater absorption and use, the Autonomous Region Housing and Construction Department tailored the following actions:

——Strengthen the leadership of standards. Unified planning guides localities to realize the scientific and systematic construction of the sponge city in the process of revising the overall city plan. When constructing sponge cities in various places, they must also tailor and prepare special sponge city construction plans based on practice, implement sponge city planning and construction, and establish storage guidelines for sponge city construction projects. Actively promote insurance and orderly construction of sponge cities.

——Catch the way of demonstration. All localities should follow the planning requirements to permeate the concept of sponge city construction in future urban construction and transformation, and surround the four major systems of buildings and communities, roads and squares, urban parks, oasis, and urban water environment. Based on the experience of the demonstration project, we will strengthen the construction of a regional sponge city.

——Intensify operation. The intensity of operations in various systems needs to be strengthened, and the construction of sponge cities is being actively and effectively promoted.

According to the "Implementation Opinions on Promoting the Construction of Sponge City" issued by the Autonomous Region Government, by the end of 2020, more than 20% of the city's built-up area will meet the requirements of the sponge city construction policy, and 70% of the rainfall will be absorbed locally and Use, natural accumulation, natural impregnation, and natural purification of the "sponge city" construction concept throughout the city planning and construction, urban rivers and lakes and mountain forests and other ecological spaces are effectively protected; by 2030, with the sponge city construction conditions More than 80% of the city's urban built-up area has reached the requirements of the sponge city construction policy.

With the continuous promotion of the construction of the sponge city in our district, the city will become more livable, and the citizen's beauty index will increase further.
