摘要
阐述了长江水生生物资源养护现状及面临问题,指出长江流域水域污染,航运发展、水工建设造成的生态环境恶化,以及非法捕捞屡禁不止是导致水生生物资源衰退的主要因素;提出完善长江水生生物资源养护和管理对策,指出必须建立适应于长江流域的渔业管理模式,治理环境污染,修复水生生物生态环境,以保护长江水生生物资源,维护水域生态安全。
The Yangtze River is the largest river in China and abundant in hydrobios resources.In recent years,the number of hydrobios species was decreasing gradually.The main reason for the declining of hydrobios resources in the Yangtze River is the worse environment caused by water pollution,water project,digging and destructive illegal fishing manner.To solve these problems,the following suggestions should be considered in the future.A new type of management suiting the Yangtze River should be established to crack illegal fishing.Water pollution should be controlled and the operation of water project should meet the demand of ecology.Also the study of hydrobios resources should be strengthened in order to protect the hydrobios resources and water ecology.
