摘要
阐述了洪湖的形成与演变历程,总结了洪湖演变的主要驱动力及其作用机制,认为地质活动和长江泛滥奠定了洪湖的成湖基础;古气候环境推动了洪湖面积变化和沼泽化过程;近代人类活动进一步加剧了洪湖生态环境的退化;三峡工程会促进洪湖生态环境的恢复,但也可能加剧洪湖的淤积。在此基础上,提出了洪湖保护的对策:完善立法,加强管理;深入开展湿地保护宣传教育,提高群众保护意识;在保护优先前提下,对洪湖资源进行适当开发利用;逐步实施包括洪湖通江在内的生态恢复措施;加强洪湖生态需水的研究,积极应对三峡工程的影响。
This paper introduced the forming and developing processes of Honghu Lake and then induced the major factors which influenced the evolution of Honghu Lake. Referred to Honghu Lake,geological activity and flood in the Yangtze River formed the precondition,and the ancient climate promoted the area change and swamp formation. Human activities accelerated the ecological deterioration in modern times and Three-gorge Project will improve ecological restoration,but hasten the soil deposition. This paper put forward the solutions for ecological protection in Honghu Lake： government should strengthen management and legislation system;public awareness and protection activity should be improved;on the premise of the protection priority,natural resources in Honghu Lake can be exploited and utilized rationally; the connection of Honghu Lake and the Yangtze River should be cons the exchange of water and fishes;and research on ecologica dered and be set into practice in order to achieve water requirements for Honghu Lake should be strengthened,and the long-term influence of the Three-gorge Project should also be assessed.
