辽阳市水鸟资源调查研究

Research on the Water Bird Resources in Liaoyang

水鸟是依赖湿地生存的鸟类类群。通过水鸟资源调查可以了解湿地生态状况,保护湿地生态系统,维护水鸟栖息环境,促进水鸟种群的繁殖和生长。了解非沿海地区的水鸟群落情况,对于掌握内陆湿地的生态状况也具有重要作用。辽阳市位于辽宁省中部东亚—澳大利西亚候鸟迁徙路径中,境内有太子河、浑河两大水系。调查该地区冬、春与秋季的水鸟种群,共设8个分区、108个调查样点。结果表明,记录到水鸟实体105975只、共45种,分属7目10科;监测到国家Ⅰ级重点保护动物2种,国家Ⅱ级重点保护动物9种。调查结果可为水鸟资源的科学研究、环境管理和生态保护提供重要信息,为保护辽阳市水鸟群落与栖息地提供重要依据。

Waterbirds are a group of birds that depend on wetlands for survival.Through the investigation of the waterbird resources,we can understand the ecological status of the wetland,protect the wetland ecosystem,maintain the habitat environment of the aquatic birds,and promote the reproduction and growth of the waterbird population.Understanding the situation of waterbird communities in non coastal areas also plays an important role in understanding the ecological status of inland wetlands.Liaoyang is located in the central part of Liaoning Province,on the East Asia-Australia migratory bird migration route,with two major river systems,Taizi River and Hun River.The study investigated the waterbird populations in winter,spring,and autumn,eight zones and 108 survey sites were set in the area.The results showed that 105975 water bird entities with 45 species were recorded,belonging to 7 orders and 10 families.Two species of national level Ⅰ key protected animals and nine species of national level Ⅱ key protected animals were monitored.The survey results can provide important information for the scientific research,environmental management and ecological protection of waterbird resources,and provide an important basis for the protection of waterbird community and habitat in Liaoyang city.
