摘要
2014年10月对綦江河流域19个调查点的鸟类种类及分布进行调查,分析山地河流鸟类多样性,筛选对山地河流生境依赖较高的傍水栖息鸟类。从傍水栖息鸟类取食类型、活动及觅食生境,探讨傍水栖息鸟类与山地河流生境之间的相互关系。研究表明,綦江河流域共记录鸟类33种,隶属7目17科。綦江河上游鸟类种类组成最为丰富,Shannon-W iener指数较高。从调查结果中筛选出10种傍水栖息鸟类,其中食虫鸟(7种),肉食性鸟类(3种)。傍水栖息鸟类食物资源主要来源于河流中的水生昆虫、水生无脊椎动物及鱼类,活动生境与觅食生境对较为固定,主要在河道内活动,是河流生态环境质量的指示生物。
In order to analyze the riverine avian diversity in the mountain rivers and explore the mutual relation- ship between riverine birds and mountain-river habitat through feeding type, activity and foraging habitat, the writers of this article conducted an investigation in October 2014 on avian species and distribution in 19 survey spots in Qijiang river. The results indicate that there are totally 33 species from 17 families, 7 classes in Qijiang river, the upstream has the richest bird species and the highest Shannon-Wiener index. The writers selected 10 species of riverine birds, including 7 insectivores and 3 carnivores, and found that the food resources of riverine birds are mainly aquatic insects, invertebrates and fishes in the river. They have a relatively firm active and forag- ing habitat, which makes them mainly move in the river, and they are the biological indicator of ecological and en- vironmental quality of the river.
