It was indicated that the water quality had been improved obviously. The water transparency maximally increased by 130%,while TP,TN and CODCrwere reduced. The density and biomass of the plankton were decreased,so was the ratio of Cynobacteria in phytoplankton community. The Shannon-Weaver index was increased; the trophic level was decreased; the ecosystem maturity was improved. By all accounts,the ＂ aquatic environment protection oriented fishery＂ had positive effects on maintaining the balance of reservoir ecosystem and ensuring the safety of drinking water.展开更多

With the continuous expansion of the ecological tourism market, however, the ecological tourism environment protection problems are becoming acute. Then, the ecological tourism will be in a fatal blow in China if the ecological tourism environment is not being protected. Therefore, improving China＇ s ecological tourism environmental protection legal system is of important practical significance to the sustainable development of tourism on the basis of introducing the experience of developed countries in ecotourism environmental protection act.展开更多
