Executive summary: In order to realize the ecological civilization construction in the Xin'an River Basin, Tunxi District has clarified the stage construction goals, taking the full implementation of the river length system as an opportunity, in the specific construction process, continuously changing the construction thinking and method, and finally realizing the Xin'an River Basin water Lay a solid foundation for the construction of ecological civilization.

The construction of water ecological civilization has the characteristics of long-term, complexity, and timeliness, and it is a dynamic shaping process, which finally makes the water ecosystem continuously in a healthy, harmonious, and sustainable state of civilization. Therefore, in order to realize the ecological civilization construction of the Xin'an River Basin, Tunxi District has clarified the stage construction goals, taking the opportunity to fully implement the river length system work, in the specific construction process, constantly changing the construction thinking and methods, and finally realizing the water ecology of Xin'an River Basin The construction of civilization lays a solid foundation.

The Xin'an River Basin is located in the southern part of the Huangshan Mountains and belongs to the Qiantang River Basin. It is the third largest river basin in Anhui Province. The area of Xin'an River in Huangshan City is 5545.1km2, of which Tunxi District is 248.9km2. There are 6 main rivers included in the district-level "river-length system" management. They are the six main and secondary streams of the Tun'an section of the Xin'an River, the Hengjiang River, the Zhanchuan River, the Zhucun River, the Pelang River, and the Dundun River, covering the entire area. 191km2.

I. Necessity of Ecological Civilization Construction in Xin'an River Basin

First, economic and social development has increased pressure on the water environment. The quality of the water environment in Tunxi section of the Xin'an River basin is generally good, but with the process of urbanization and industrialization, the continuous advancement of agricultural development, and the continuous development of tourism, the permanent population and floating population in the area will increase significantly, and the amount of sewage and pollution The amount of material produced will also increase, and higher requirements will be imposed on the treatment of water pollution sources, and the water environmental protection pressure on the Xin'an River will increase.

Second, the capacity of water regulation is insufficient, and downstream ecological security is difficult to guarantee. The rainfall in Tunxi District is uneven, and there is a lack of water storage and storage projects. During the flood season, rapid floods and river dry-outs in the dry season impact on the ecological security of the basin. In recent years, the dry runoff of the Xin'an River in the dry years and dry seasons is insufficient. The average dry flow of Tunxi Station is 12.6 m3 / s, and the minimum flow is only 1.3 m3 / s. The vegetation environment has adverse effects.

Third, human activities are frequent and the water ecosystem is degraded. Tunxi District's favorable climatic conditions, unique river systems and hydrological conditions have bred rich biological resources and biodiversity. After years of restoration and construction, the water ecology has been well restored. However, due to the construction of flood protection facilities such as dike protection banks, sand mining and other artificial activities, the hydrological situation of the river has been changed. The vegetation structure of the Xin'an River system is relatively incomplete and more common. The biomass of wetlands and marsh plants has a tendency to decrease, and aquatic animals and fish in dry and tributary rivers are also gradually decreasing.

Therefore, the idea of water ecological civilization should be penetrated into all links and the entire process of water conservancy development in the Xin'an River Basin, and the ecological civilization of the Xin'an River basin should be taken as a long-term task to comprehensively promote the construction of ecological civilization in the Xin'an River basin and promote the development of the entire region It is of great strategic and practical significance to go on a civilized development path with a rich life and a good ecology.

2. Full implementation of the river length system in Tunxi District

The full implementation of the river length system is a major decision and arrangement made by the Party Central Committee and the State Council to strengthen the management and protection of rivers and lakes, and is a system innovation to improve the water governance system and ensure water safety. In the process of studying Xi Jinping's thoughts on ecological civilization and the construction of water ecological civilization, the full implementation of the river system has become a key measure.

In order to strengthen river management and water ecological protection, Tunxi District has implemented a river length system.

The first is to improve the program system. At present, all district-level, town-level, and village-level river length work plans have been issued.

The second is to improve the organizational system. The district has established a leading group for the overall implementation of the river system. It has a river system office. The director is the main responsible comrade of the district water conservancy bureau, and the full-time deputy director is the comrade in charge of the district water conservancy bureau. 2 persons, one responsible comrade from each of the District Construction Committee and the District New Insurance Bureau. The liaison officer of the district-level river mayor conference member unit is a member of the district river-may office.

The third is to establish a "hechang" network with full coverage. The secretary of the district committee and the district chief are the chief river chiefs at the district level, the district committee members and executive deputy district chiefs are the deputy chief river chiefs, and the deputy district heads of the district governments are the six major and minor river chiefs. According to the place where the river flows and the reservoir, the chief comrade of the town party committee and government is the chief river chief at the town level, and the village director is the river chief at the village level. At present, the district has specified 86 rivers at all levels, responsible for the management of 24 rivers with a river length of more than 1 kilometer, and the river length system is fully covered.

The fourth is to compile a policy. Focusing on the six major tasks proposed by the river-length system work plan, 18 major tasks and 45 sub-tasks were detailed. A township-level survey of river banks was initiated to find out the current status of river banks, establish one river and one file, and implement one river and one policy. The "one river and one policy" at the district, town and village levels has been fully compiled, and targeted river management measures have been taken.

Third, the river system has achieved remarkable results

Through the comprehensive implementation of the river length system, the water ecological civilization construction in the Xin'an River Basin has achieved good results.

First, the source of pollution has been initially addressed. Strengthen industrial pollution control, and implement 24-hour monitoring of sewage outlets of key pollution source enterprises. Strengthen the management of agricultural non-point source pollution, strengthen the prevention and control of pollution in livestock and poultry farming and aquaculture, and centralize the management of livestock and poultry farming enterprises. Promote the comprehensive utilization of agricultural waste such as straw, and investigate and punish acts that destroy fishery resources in accordance with the law and regulations. Strengthen the management of domestic pollution sources. The centralized treatment rate of urban domestic sewage and the harmless treatment rate of urban domestic garbage reached 95% and 97%, respectively.

Second, the water quality of the river continued to improve. Establish a leading group for sand reclamation in rivers in the district to comprehensively clean up and rectify sand in the rivers in the district and shut down 5 sand and gravel processing plants within the drinking water source. Strictly crack down on all kinds of illegal sand mining behaviors, and all types of water violations in the region have been comprehensively curbed. Strengthen river water quality observation and focus on law enforcement inspections of enterprises along the river. The quality of drinking water sources maintains Class II standards throughout the year.

Third, the social atmosphere is getting stronger and stronger. Since the implementation of the river length system, our district has carried out city and district level river cleaning special activities. It has set up district, town, and village river level public signs, river length publicity boards, and slogans, and made full use of slogans and television. , Internet, publicity bar, and other forms to effectively enhance the public's awareness of environmental protection, to stimulate the enthusiasm and sense of responsibility of the general public to participate in water environmental protection. Carry out the river-length system to create a good atmosphere.

The construction of ecological civilization in the Xin'an River Basin is a complex project and cannot be achieved overnight. Tunxi District will actively meet the challenges, improve and repair the Xinan River Basin ecosystem, and make it develop harmoniously with the human social system, so as to reach the goal of Xinan River Basin Ecosystem to meet people's spiritual and cultural needs, and finally realize the ecological civilization construction of Xinan River Basin.
