Abstract: Taihu Lake area, lying in the center of developed area in Eastern China,is one of the most prosperous places, being famoucs for its rich aquatic products and rice, wonderful scenery and human scenic spots. More than eight thousand years has passed before what we see now. Long history evolution has developed its very special culture. However, economic development and environment protection have been entwined to each other so tight in modern times that Taihu Lake area cannot escape the magic chain either. Many problems emerge with the development of modern industry. The one that this article focuses on is eco rehabilitation in open mining area and its coordination with eco tourism. How to solve this problem is critical to a healthy Taihu Lake in the future. This article may provide a possible development mode for its further eco tourism exploitation.Based on the theory of landscape ecology, the article provides the principles and methods on how to solve the problems caused by open mining around Taihu Lake. Firstly, reasonable planning of eco rehabilitation should be made on a large scale since every single open mining is a fragile ecosystem. Secondly, suitable conditions are created to serve the re habilitation and re construction of the whole system. Figures of ecological function system and ecological function area relationships have been built up according to the aim of eco rehabilitation: biological production, environmental service and cultural support. Each of the three functions directly faces to special uses of a particular open mining, such as biological production to agriculture lands, environmental service to tourism, entertainment and grass lands, cultural support to construction lands. Finally, the possible environment, ecological and economical benefits are discussed following the eco rehabilitation of open mining.
