摘要
简要介绍了长江中游湿地的概况,分析了湿地演变的现状。在自然和人为因素长期、综合作用下,长江中游湿地发生了显著的不合理演变,主要表现在:湖泊面积减少,湿地功能下降;湿地资源的过度和不合理利用,生物多样性下降;湿地环境污染日益严重;湿地整体价值受损。重点对湿地系统演变过程中的几个关键驱动关系进行了探讨,包括江湖关系、蓄泄关系、湖垸关系和山湖(河)关系等。在此基础上,针对长江中游湿地演变的现状和利用保护过程中存在的问题,从流域综合管理角度出发,对长江中游湿地的保护进行了展望,提出了基于流域管理思想的长江中游湿地保护对策和措施,主要包括:加强流域统一协调管理;遵循流域管理原则,理顺湿地系统的各种关系,做好湿地生态规划;加强流域生态管理模式研究;加强长江中上游流域水土流失的综合治理;加强自然保护区建设和管理,保护湿地生物多样性。
In this paper, we firstly introduced briefly the wetland in the middle reaches of the Yangtze River, and then analyzed the actualities of wetland evolvements affected by integrated physical and anthropic factors, including atrophy of wetland area, decline of wetland functions, immoderate and excessive exploitation and utilization of wetland resources, the decrease of bio-diversity, increasingly serious pollution of the wetland environment and damage of the wetland whole value. And then we discussed the evolvement of several relationships in the evolving process of the wetland, including relationships between the Yangtze River and related lakes, flood storage and discharge, related mountains and lakes （rivers）, lakes and polders. Finally, we highlighted prospects in wetland conservation by proposing some countermeasures on the basis of river basin integrative management（;RBIM）, including the unification of the river basin integrative management, the better programming ofwetland conforming to the principles of RBIM and the organization of all relationships in relation to wetland systems, strengthening of eqologioal management pattern research and comprehensive treatment of the soil and water loss in the uppter and middle reaches of the Yangtze River, as well as the construction and management of wetland nature reserve, and protect the wetland bio-diversity.
