摘要
为了深入了解鄱阳湖区堑秋湖的生态现状,应用鱼类生物完整性指数评价方法对南矶湿地保护区内6个堑秋湖水域进行完整性调查和生态评价。结果显示,南矶湿地堑秋湖内有鱼类36种,隶属于6目11科,其中鲤科鱼类25种,皆为本土物种;样品鱼类肉食性次级消费者鱼类物种多样性较为丰富,杂食性的物种个体较多;耐污性鱼类27种,敏感性鱼类9种;无显著畸形和严重病菌感染的鱼类个体。由鱼类生物完整性指数得分可知,6个样点湖泊中5个湖泊水域处于一般健康状态,1个湖泊水域处于健康状态。
In order to deeply understand the current ecological situation of Lake Enclosed in Autumn in Poyang Lake area,six waters in Lake Enclosed in Autumn in Nanji Wetland Reserve were investigated and evaluated by using the method of fish index of biotic integrity. The investigation showed that thirty six species of fish,which were all native species,belonged to six orders and eleven families. Among them,twenty five species were of Cyprinidae. The species diversity of carnivorous secondary consumers was relatively rich,and the omnivorous individuals were more. There were twenty seven species of pollution tolerant fish and nine species of pollution sensitive fish. No fish individuals with significant deformity and serious bacterial infection were found. The scores of fish index of biotic integrity showed that five waters in Lake Enclosed in Autumn were generally healthy and one was healthy.
