【摘要】 铜陵江段是长江下游长江江豚(Neophocaena phocaenoides asaeorientalis)种群数量最集中、密度最大的江段之一。但随着人类活动的影响,长江江豚的资源保护也凸现出诸多问题。综合已有的研究资料和最新的调研结果,对其存在的问题进行了分析。认为植被人为演替、肆意采挖江砂、大型水利工程建设和江湖通道阻隔等是其面临的主要问题。同时,针对性地提出加强部门协同管理、协调经济发展和生态保护的关系、恢复江湖连通等措施和建议。更多还原

【Abstract】 Tongling section is one of important sections in the lower of Yangtze River where Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis could be found frequently with maximum quntity and density. However, with the influence of human activities,many problems that may affect the long-term conservation of Yangtze finless porpoise began to emerge,which were analyzed in this paper based on the comparison between the published data and the latest investigation results. The major problems identified include the artificially vegetation succession ,the wantonly dig sand,built great irrigation works,and the disconnection between lake and river,etc. Countermeasures and suggestions for conservation of Yangtze finless porpoise were put forward as follows: 1) tighten up the management with various government departments; 2) harmonizing the relationship between Yangtze finless porpoise conservation and development of local economy; and 3) opening lock between lake and river.更多还原
