由长江中的三种鲟到长江水域生态保护

通过系统整理长江中三种鲟与长江水域生态保护文献的基础上，描述了这三种动物的生物学特征，梳理了白鲟灭绝、中华鲟与长江鲟极度濒危的历程.从长江水域生态保护的角度，分析了导致长江生物多样性严重下降的因素，包括水利工程、酷渔滥捕、水质污染、航运与采砂等人类活动.针对性地提出了8个方面的保护对策：实施生态修复、十年禁渔、加强保护区建设、生态调度、控制水污染、加强监测和研究、健全生态补偿机制、建设国家级保种基地.

From three sturgeons to the ecological potection of the Yangtze River

In this literature review on three sturgeons and ecological protection of the Yangtze River， the authors described the biological characteristics of these sturgeons and introduce the process of Chinese paddlefish's extinction and Chinese sturgeon and Yangtze River sturgeon's critically endangered status. From the perspective of ecological protection of the Yangtze River， the factors leading to the serious decline of biodiversity in the Yangtze River were analyzed， such as water conservancy projects， overfishing， water pollution， shipping and sand excavation， and other human activities. Accordingly， eight protection countermeasures were proposed， including ecological restoration， 10-year fishing ban， natural reserves' construction， ecological operation， water pollution control， monitoring and research， ecological compensation， and national conservation bases' construction.
