【摘要】：由于近几十年的生境破坏和人类活动,江豚的生存面临极大的威胁,野生种群数量正快速衰减。针对江豚当前面临的威胁,如渔民误捕误杀、水上运输业的影响、水环境污染、饵料生物资源量下降、水利水电工程的影响等,探讨了必须采取的相应保护措施,如在江豚活动密集区建立自然保护区,在江豚频繁出现的水域限制过往船只的航速,提高长江流域渔民的豚类知识和保护意识,针对水利水电工程在施工过程中和完工后可能对江豚造成的威胁,制订积极有效的保护措施等。
[Abstract]:As a result of habitat destruction and human activities in recent decades, the survival of the finless porpoise is facing a great threat, and the number of wild populations is rapidly declining. In view of the current threats to the finless porpoise, such as by-catch and manslaughter by fishermen, the impact of the water transport industry, and the pollution of the water environment, The decrease of feed biological resources and the influence of water conservancy and hydropower projects are discussed. The corresponding protection measures are discussed, such as establishing nature reserves in the areas where the finless porpoise activities are concentrated, and limiting the speed of passing vessels in the waters where the porpoise frequently occurs. In view of the threat that water conservancy and hydropower projects may pose to the finless porpoise during construction and after completion, active and effective protection measures are formulated.
