Study on the Current Situation and Improvement Mechanism of Comprehensive Management of Rural Human Settlement Environment in Dazhou

Under the guidance of the Rural Revitalization Strategy, the comprehensive management of rural human settlement environment is an important path to promote the modernization development of rural areas in Dazhou and make rural people feel happy and satisfied. Therefore, it is necessary for Dazhou to explore the sustainable development strategy of comprehensive management of rural human settlement environment, so as to effectively optimize the rural human settlement environment. Based on the analysis on and discussion about the current situation of comprehensive management of rural human settlement environment in Dazhou, this paper analyzes the difficulties existing in the comprehensive management of rural human settlement environment in Dazhou, such as insufficient construction of supervision mechanism, lack of management funds, lack of complete infrastructure, weak awareness of environmental protection of villagers, and lack of the construction of talent team. It is proposed that for rural human settlement environment management in Dazhou we should establish the long-term management mechanism, system construction mechanism, constraint incentive mechanism, village self-management mechanism, university linkage mechanism and other improvement mechanisms, in order to realize the overall improvement of rural environment.

nicipal Committee in 2019, it was clearly pointed out that in 2019 the domestic sewage in more than 50% of the administrative villages was effectively treated; in 2020 the domestic waste in more than 90% of administrative villages would be effectively disposed of; in 2019 the popularizing rate of sanitary toilets for rural users in the whole city was above 70% and there was a public toilet in every administrative village, and in 2020 the comprehensive utilization rate of fecal residue and waste water would be above 75%. There is still a certain gap between Dazhou and Sichuan Province in terms of rural human settlement management objectives, such as the treatment rate of rural domestic sewage and popularization rate of toilet. Therefore, the systematic and comprehensive research is of great practical significance.

Current Situation of Development of Comprehensive Management of Rural Human Settlement Environment in Dazhou
By the end of December 2019, Dazhou has 315 towns (townships and subdistrict offices). It is a county with a large population and an agricultural county in Sichuan Province. It has jurisdiction over 4 counties, 2 districts and 1 city. There are a total of 8 subdistrict offices, 106 towns and 201 townships. The permanent resident population of Dazhou is 5.741 million, of which the rural population is 3,034,700, accounting for 52.86%. Dazhou has a large proportion of rural population. The task of rural human settlement management is tough.

1) Strengthen the rural sewage treatment
Dazhou is fully aware of the importance and urgency of promoting rural sewage treatment. First, it takes accurate measures and implements orderly; second, it integrates resources and solves the fund problem; third, it monitors the transportation process and intelligently maintains. After a series of measures were taken, by 2019, in the whole city the construction of sewage treatment system in 10 key towns has been completed, and 10 sewage treatment demonstration villages will be built. By 2020, the domestic sewage will be treated in about 50% of administrative villages in the whole city, the rural domestic sewage treatment and black and odorous water body treatment tasks in key areas such as the banks of main streams and tributaries of Qu River and drinking water source protection zones will be completed, and there will be sewage treatment facilities in every town and township.
2) Promote the domestic waste treatment In order to strengthen the management of rural domestic waste in Dazhou, create clean and tidy villages and improve the rural human settlement. First, the collection and treatment mode of domestic waste is improved. The waste collection, transportation and treatment mode of "household collection, village collec-

5) Promote village planning and management
According to the requirements of spatial planning, Dazhou connects and integrates the original village planning, village construction planning, land use planning of village, land consolidation planning and other rural planning, the compilation of village planning is comprehensively promoted, and the full coverage of village planning management is promoted. According to the requirements of "integrating multiple planning", Dazhou will complete the rural construction planning of Tongchuan District, Dachuan District, Dazhu County, Quxian County and Kaijiang County, and make more than 1,000 characteristic and practical village plans. By 2020, the task of compilation of characteristic and practical village planning will be basically completed, and the coverage rate of administrative village planning and management will be above 80%. The villages and towns of Dazhou consider rural revitalization and improvement of rural human settlement as the ultimate goal, adhere to the principle of "no construction or investment without planning", and strengthen the management of village planning. Once approved, the village planning must be strictly implemented. No department or individual is allowed to modify or change it illegally.

Real Difficulties of Comprehensive Management of Rural Human Settlement Environment in Dazhou
Although Dazhou has made a lot of achievements in the comprehensive management of rural human settlement environment, its achievements are still far from those in the rural areas of the whole province or developed areas and the expectations of farmers. The comprehensive management of rural human settlement environment in Dazhou has the following real difficulties: First, the construction of supervision mechanism is insufficient. The management of human settlement environment relies on administrative control means. However, the environmental protection agencies at the county level still lack the supervision and implementation ability, and there is no management subject at the town and village level, which affects the solution of environmental problems (Xu, 2020). Although the government has issued some treatment There are difficulties in improving the human settlement environment.

Improvement Mechanism of the Comprehensive Management of Rural Human Settlement Environment in Dazhou
First, the trinity working mode shall be innovated and a long-term management mechanism shall be established. First, starting from the management and protection mechanism, the construction of rural professional cleaning team and the consolidation and implementation of the long-term management and protection mechanism shall be promoted (Zhang, 2019). Second, starting from the fund guarantee mechanism, the government shall coordinate all kinds of funds to strengthen the investment in the management of human settlement environment. A diversified investment guarantee mechanism of rural cleaning funds dominated by public finance of the government, raised by villagers' committees and villagers, paid by beneficiaries and supported by social funds shall be established. Finally, starting from the participation mechanism, the long-term guarantee for the leadership of grass-roots organizations, technical advantages of enterprises and strengthening of the management of rural human settlement environment shall be realized.
Second, the setting of specific executing agencies shall be refined and the institutional construction mechanism shall be improved. On the one hand, the grass-roots government shall set up a special leading group to play the role of organization, supervision and inspection, improve the construction of mechanism of division of labor, define the specific leaders in charge, adhere to the principle of "coordination and cooperation of departments and joint action of all parties", and implement the strip and block linkage and the combination of full-time and part-time staffs (Zou, 2020). Each shall perform his or her own duties. On the other hand, the construction of legal system shall be strengthened, local regulations and administrative provisions shall be improved, the relevant rural special environmental protection laws and regulations shall be established, and the illegal acts of breaking the rural ecological environment shall be strictly punished. The specific management systems such as regular meeting system, standing book system, information disclosure system, responsibility assessment and rewards and punishments shall be implemented. They shall restrain, encourage and supervise the behaviors of subjects relying on the system guarantee.
Third, the implementation of the supervision and guarantee system shall be promoted and the restriction and incentive mechanism shall be implemented.
Governments at all levels shall actively perform their own functions; incorporate the society, market, collective organizations of villages, villagers and other subjects into the management mechanism of human settlement environment; define the distribution of rights and responsibilities of supervision subjects at all levels; realize personal responsibilities; establish a 3D supervision network chain; and create a working situation of multi-party participation and good interaction by realizing the multi-channel and open construction of management affairs with WeChat and network platform. Fourth, the cultivation of villagers' self-government concept shall be strengthened and the mechanism of villagers' self-government shall be constructed. On the one hand, the construction of villagers' self-government organizations shall be promoted, villagers' opinions shall be widely solicited through open elections, the non-principle problems involved in the process of environmental pollution control shall be solved by democratic consultation, and a good social management atmosphere shall be created (Jiang & Li, 2020). On the other hand, the publicity of environmental management shall be strengthened, the propaganda method popular which is loved by people and easy to understand shall be used to guide the villagers to establish the concept of self-management, a strong atmosphere of everyone's concern and household participation shall be created, and the effectiveness of rural human settlement environment management shall be improved.

The sustainable construction of management of the rural human settlement environment cannot be separated from talent guarantee. Therefore, the university talents shall be taken as the subjects and the linkage mechanism of university classroom shall be relied on for the innovation and sustainable development path of the management of human settlement environment. Specifically, a long-term cooperation relationship shall be established with local colleges and universities (such as Sichuan University of Arts and Sciences or Dazhou Vocational and Technical College), college students shall be guided to contribute creative ideas and innovative ideas for the management of rural human settlement environment, and the excellent results shall be applied to the actual work of rural environment management, so as to further provide intellectual guarantee and talent support for the management of human settlement environment.

Conclusion
In recent years, the importance of the management of rural human settlement DOI: 10.4236/jss.2020.811009 98 Open Journal of Social Sciences environment in "Rural Revitalization" is gradually highlighted, and people's attention has also been greatly improved. More and more areas in Dazhou have explored the management of rural human settlement environment and achieved some results. Nowadays, the people's yearning and demands for a better life are higher and higher. Therefore, the management of rural human settlement must start from reality. We should not only focus on a few typical villages, demonstration villages and model villages, but also pay attention to each administrative village in Dazhou and establish a systematic and complete improvement mechanism, so as to realize the overall improvement of rural environment. Therefore, facing the existing problems, villages, the society and the government shall interact positively and manage jointly. The initiative, enthusiasm and coordination of governments at all levels, village committees and villagers shall be improved. The rural methods shall be adopted, including the establishment of basic principles, working paths, financing construction and technical models suitable for rural areas. We shall adjust measures to local conditions, take measures suitable for the village, and try our best according to our ability. However, we shall not use the one-size-fits-all approach, achieve effective results step by step, and make the long-term contributions, so that villages can be clean, green, beautiful and cultural and the goal of beautiful rural construction can be achieved. Rural construction is an eternal development theme, but this paper is not comprehensive enough to investigate the situation of rural governance in Dazhou, and the improvement mechanism stays at the theoretical level. I hope that the follow-up research on such problems can put forward some operational countermeasures and suggestions.
