摘要
湿地是地球上重要的生存环境和生态系统,有“自然 之肾”的美誉。长江中下游流域是我国湿地分布集中的区 域,我国著名的五大淡水湖均分布于此。长江中下游滩地比 较独特的特征可以概括为:冬陆夏水,枯水一线、丰水一片; 面积广大、生物多样性丰富;条件优越、经济发达;人口密 集、灾害频繁等。长江中下游湿地的重要性不但吸引了广大 学者、专家对其进行研究,而且也引起了国家和国家领导人 的重视。彭镇华、江泽慧等本着以人为本的湿地保护原则, 创造性地提出了抑螺防病林作为一个新林种的新概念,建立 了一套较为完整的理论和实践体系。这一理论不但极大地丰 富了我国滩地林业生态工程理论,而且实践证明其经济、生 态、社会等复合效益十分可观,是灭螺防病和长江中下游流 域湿地开发相结合的行之有效的生态措施。长江中下游湿地 的建设要遵循国家正确方针的指导,本着以人为本,坚持生 态建设的道路,加强长江中下游湿地建设的立法工作,着重 就长江中下游湿地关系到国计民生和地区可持续发展的功能 进行深入研究。在党和国家的关怀、支持下,在广大学者、 专家的努力下,长江中下游湿地必然会发挥出其重要的作 用,为国家的可持续发展做出其应有的贡献。
Washlands in the middle and lower beaches of the Changjiang River are the regions where wetlands are widely distributed. The wetlands here are characterized by water logging during summer and water withdrawing during winter, vast area with rich biodiversity, densely populated, developed economy and frequent disaster, etc. The uniqueness and importance of the wetlands attract the attention of scientists and state leaders. The development of wetlands in the region should follow the scientific directions and the guidelines of state policies. It is suggested that the development of the wetlands in the region must firstly take the man＇s health and ecology into consideration. Legislation on the development of wetlands should be strengthened. Studies on people＇s health ,and sustainable development of the wetlands should be carried out. With the scientific guide and policy support, the wetlands in the middle and lower reaches of Yangtze River are expected to play a more important role in and contribute to the national sustainable development.
