摘要
铜陵淡水豚国家级自然保护区(简称铜陵保护区)是长江下游唯一既开展就地保护、又开展迁地保护的机构,而铜陵江段历来是长江江豚分布最密集、数量最集中的江段之一。通过近几年铜陵保护区长江江豚的考察,得悉铜陵保护区长江江豚的种群数量正在下降,生存形势日益危急。文章对铜陵保护区长江江豚致危原因进行了分析,针对性地提出在加强就地保护的同时,应着重加强迁地保护,建立多个迁地保护水域,更好地保护珍稀物种长江江豚。
Tongling River Dolphin National Nature Reserve （Tongling Reserve） is the only institution for situ and ex-situ protection in lower reaches of the Yangtze River. And Tongling section of the Yangtze River has always been one of the most densely distributed and the most concentrated amount of river dolphins. With the development of Tongling economy and the deterioration of the ecological environment of the Yangtze River, the amount of river dolphin in Tongling Reserve is declining and the survival situation is increasing-ly critical through the investigation in recent years.This article analyses the risk reasons of river dolphins in Tongling reserve and puts forward specific measures to strengthen the situ protection, at the same time to focus on ex-situ protection and establish a number of ex-situ protection waters for better protection.
