Exploration of Eco-friendly Use of the Littoral Zone of Three Gorges Reservoir:Dike-Pond Project as a Case Study

As results of the anti-season fluctuation of the water level,some eco-environmental problems have been taken into the littoral zone of Three Gorges Reservoir unavoidably,but it also offers us an opportunity to make use of this area.The purpose of this paper is to find an eco-friendly way to make use of the land in the littoral zone as well as the eco-environmental problems been dealt with.And the dike-pond project,an eco-friendly use of the littoral zone which was designed based on the seasonal water level change and the character of the landform,was discussed in this article.The ecological and economic benefits of dike-pond system were appraised through the production and the biodiversity change.The results showed that there was an considerable economic benefit generated from the dike-pond system,and the composition of the plant species is different between the dike-pond system and the contrast area.Compared with the contrast area,there were much more hydrophytes and less terrestrial plant in the dike-pond system.It was obviously that the dike-pond project is an eco-friendly way fitting to the littoral zone of the Three Gorges Reservoir,and it was helpful to improve the wetland environment and protect the biodiversity in the littoral zone.
