Abstract: The wetlands along any lakeside are the “crossover” between the water and land ecosystems associated with the lake. They form an important part of any lake ecosystem and provide a function for the general environment and ecosystems as well as performing water volume adjustment and storage. They also provide a protection barrier for any lake.
The major problems of the wetland along the lakeside of Erhai are: (1) The wetland along the lakeside is bordered by man-made architectural structures. (2) Non-point sources of pollution are prominent (3) The structure of the wetland ecosystem has broken down and the ecosystem environment is deteriorating and (4) the natural view of the wetland is seriously compromised. In recent years the citizens of Dali have recognized the seriousness of the problem. They have begun to eliminate the human interference, lowered the pollution loads entering the lake and implemented environment protection as well as carrying out dredging and ecosystem restoration of the wetland along the lakeside.
While introducing methods of ecosystem restoration, its technologies and the effects on the wetland along the lakeside, this paper also discusses issues such as (1) How to have reasonable orientation and be able to restore the natural ecosystem of the wetland (2) How to combine the local social economy and tourism spots (3) Achieving a reasonable handling of the relationship between the utilization and protection with the consideration for farmer’s benefits and (4) Fulfilling the organic unification of wetland maintenance with economic development.
