安庆沿江湖泊湿地自然保护区生物多样性及保护对策

目的]为保护湖泊湿地的生态环境提供依据。方法]在野外实地调查、查阅历史文献的基础上,分析安庆沿江湖泊湿地自然保护区动植物的物种多样性及其演变趋势和驱动力,针对性地提出了该自然保护区生物多样性保护的建议和对策。结果]该自然保护区共有湿地维管束植物152种,鱼类81种,鸟类188种,两栖类动物12种,爬行类动物20种,浮游动物105种,底栖动物71种,兽类28种。受环境变化、生态阻隔、资源开发的影响,该自然保护区植物种类减少,优势种群不断更替,动物物种数量稳定,物种组成变化显著。结论]该自然保护区通过加强小流域生态环境建设、适度开发湿地资源、畅通生态通道等措施,可提高生物多样性。

Biodiversity and Its Protection Countermeasure in Lakes and Wetlands Nature Reserve along Yangtze River in Anqing

Objective] The study was to provide the basis for protecting ecological environment of lakes and wetlands.Method] On the basis of field investigation and historical documents consultion,the species diversity of animals and plants and their evolution trend and driving force in lakes and wetlands nature reserve along Yangtze River in Anqing were analyzed,and the suggestion and countermeasure for biodiversity protection in this nature reserve were proposed properly.Result] In this nature reserve,the species of vascular plants,fishes,birds,amphibian animals,reptiles,zooplanktons,zoobenthos and mammals were 152,81,188,12,20,105,71 and 28 resp..Being affected by environmental change,ecology barrier and resource development,the plant species in this nature reserve was decreased and their dominant population continuously alternated,the specie number of animals was stable and the change of specie components was significant,Conclusion] In this nature reserve,through strengthening ecological environment construction of the small watershed,moderate exploitation on wetland resources,unblocking ecology corridor etc measures,the biodiversity could be increased.
