摘要
三峡库区消落带是库区陆域与水库之间生态过渡与缓冲带,是我国最大的人工湿地。三峡库区大面积消落带及其敏感的生态环境问题,对水库的正常运行、水环境质量和库区群众的生产生活都产生了重要影响,已经成为当地政府和国家关注的重大环境问题。通过对三峡库区消落带内桑树耐反季节水淹特性的观察分析,论证了在库区发展蚕桑生态经济的可行性、发展潜力以及发展模式,为库区消落带植被修复、环境整治和农村经济发展的决策和实践提供参考。
The water-level-fluctuating zone of the Three Gorges Reservoir performs important ecological functions for both the water body and land areas, Recently, severe environmental problems in the Three Gorges Reservoir area where the ecological environment is extremely fragile, become a focal point of local government＇s attention, and will greatly influence reservoir operation, water enviromnent quality and production and life of people living there. In the present paper, the anti-season waterlogging resistance characteristics of mulberry is analyzed, and it is demonstrated that it is feasible to develop an ecological economy of sericuhure in the Three Gorges area. A development model is proposed and its potentiality is analyzed to provide some guidances for policy making and practice in plant restoration in the water-level-fluctuating zone, environmental management and development of the rural economy in the Three Gorges Reservoir area.
