Study On Water Pollution Assessment And Ecological Restoration In Old Town Of Lijiang

Old Town of Lijiang with its beautifully natural and cultural landscape has become one of the important tourist destination at home and abroad.Known as the Plateau Gusu,water landscape is the soul of Lijiang ancient town.Water landscape is an important part of Lijiang’s ecological and geological environment of.However,with the rapid development of urbanization,the development of the third industry represented by the pillar industries becomes very fast.While it has also lead to a series of social and environmental problems.For example,the rapid increase of population,the acceleration of environmental pollution,the pollution of water,the decrease of water quantity and so on.They affect the development,utilization,distribution,protection and management of water resources in Old Town of Lijiang and seriously restricted the creation of tourist image and development of the ancient city water landscape.As facing the serious development problem of Old Town of Lijiang,scientific study on the causes of water pollution and water reduction of the waterbody,systematical analysis on the analyze the social,economic,climate,precipitation,river,groundwater,springs and other basic natural and social information of the study area,deeply exploration of the water supply relationship between the main source of waterbody and the surrounding springs,objective and feasible measures which are put forward to solve the water pollution and reduction of waterbody are specially important to the sustainable development of waterbody in Old Town of Lijiang.On the basis of previous studies,this paper makes a correlation analysis and research on the relationship between the spring water flow and the water supply relationship through the study of the climate,precipitation,river system,hydro-geology and surrounding spring in the study area.The relationship between the main source of the waterbody and the decrease of the water quantity in the ancient city were determined by using the tracer linkage experiment to determine the recharge relationship between the main source of the ancient waterbody and the surrounding spring group.At the same time,by collecting and analyzing the data of waterbody,the paper studies the pollution status,and finds out the main pollution factors of the ancient city waterbody.Based on the analysis of the water environment of the ancient city waterbody,through the in-depth investigation of the waterbody and its water resources in the ancient city of Lijiang,with the objective analysis of the above problems,and in the view of waterbody ecological restoration,combined with ecological theory,this paper concretely describes the solving programs to restoration,protection,upgrading and construction of waterbody in ancient city of Lijiang trying to make contribution to protect the waterbody of ancient city in Lijiang and construct healthy and beautiful living and tourism environment.
