淮河流域(安徽段)重要湿地鸟类多样性研究

Biodiversity on birds of important wetlands in Huaihe river basin in Anhui,China

采用定点法、路线法和访问调查法,对淮河流域(安徽段)6处重要湿地的鸟类进行调查,共记录鸟类146种,隶属于15目48科.其中冬候鸟53种,夏候鸟42种,留鸟37种,旅鸟14种;古北界77种、东洋界23种、广布种46种;游禽31种、涉禽34种、陆禽8种、攀禽11种、猛禽10种、鸣禽52种.分析表明,该区域重点保护的鸟类较多,水禽比较丰富,还有种类较多的森林鸟类和灌丛鸟类.6处湿地中,女山湖的鸟类物种数最多,G指数、F指数以及G-F指数值均最高,两块湿地地理位置相差越远相似性系数就越小.

The birds of important wetland in Huaihe river basin in Anhui were surveyed with the method of fixed point,line intercept and visit investigation, a total of 146 species of birds, belong to 15 orders and 48 families were recorded.
