Ecological Restoration Planning Of The Pailougang Creek In The West Maori Lake Of Jinshi

In recent years,the rapid development of economic society in China has seriously affected the resources and environment,the quality of water resources has declined,the water ecosystem has deteriorated,and some water bodies have lost their use function,which seriously threatens the ecological security and water supply security,and restricts the sustainable development of Economic society.Under this background,it is urgent to advance the water resources protection and water ecological restoration work in the basin.West Maori Lake,as the second inner natural freshwater lake in Hunan Province,is also a direct drinking water source in the neighboring towns,it is necessary to carry out ecological restoration planning of the tributary archway in the area where the pollution problem is more prominent,to restore its ecosystem,and to ensure that the water quality of the water from the West Maori Lake to reach the second type of surface waters.The thesis is to restore ecology theory,based on the theory of landscape ecology and the theory of ecological engineering,using the research methods of data collection and collation,literature research,field investigation and investigation,and combining with the actual problems in the basin,the ecological restoration planning of the Pailougang Creek is as follows:(1)The relevant theoretical knowledge is integrated and combed:the background and purpose,method,content and technical route are integrated and sorted,and the related concepts and theoretical basis of watershed ecological restoration are sorted,and the theory method of river ecological restoration planning in the area of Pailougang Creek basin is conceived.(2)Case Reference and research framework:by summarizing the methods of restoration planning of river ecosystem and watershed water quality in 5 cases at home and abroad,the paper also finds out the important purpose and significance of ecological restoration practice,so as to guide the whole research frame of the thesis.(3)The present situation and location of the Pailougang Creek the upper planning and river ecological problems are specified,and the planning objectives,concepts,positioning,strategies and deadlines are defined,and the population and pollution amount in the basin is forecasted;Through the watershed ecological problems,we can recognize the function zoning of the Pailougang Creek basin,To carry out ecological rehabilitation planning for the main problems of each partition,and put forward the specific measures of ecological restoration,including land use coordination planning,pollution source control,river Ecological rehabilitation planning,artificial wetland planning,plant ecological restoration planning and ecological management planning of the base,so that the pollution in the basin to contain,improve the living environment of villagers,The ecosystem was restored and the water quality reached the water quality of type ?.Finally,the proposed practice strategy of watershed Ecological restoration planning is summarized and supplemented.The ecological restoration planning of the Pailougang Creek basin can make the water quality reach the surface water Class ?,but a damaged ecosystem cannot be restored to its original "natural state",and it is unlikely to create a new ecosystem in the short term,and only by creating conditions that enhance the self-organization of the river ecosystem,based on the status of damage and various favorable factors,Gradually restore the river ecosystem.Therefore,after the implementation of the scheme,the project measures must be monitored for a long period of time,and the data of the engineering measures will be recorded in detail and accurately.At the same time concerned departments need to always pay attention to the role of the system in the basin coupling.As for the Pailougang Creek,how to ensure the river ecological water demand,biodiversity,monitoring the pollution source in the basin,restoring the deep pool of river longitudinal shoal,resuming the vertical natural continuity and the time natural continuity of the river is not negligible,so we need to solve it one by one.In the present,only the comprehensive systematic planning can truly embody the restoration goal that the advanced ecological restoration idea of "near nature,multi-function,high efficiency and sustainable"should be achieved.
