| 摘 要： | 基于Arcview GIS平台,对长江上游水域的重要经济鱼类、珍稀特有鱼类的生物学特性、地理分布以及理化因子、生物环境、沿江水工建筑等进行分析,发现水利工程、过度捕捞、水域污染等人为活动对长江上游的生态环境影响明显,致使与之高度相适应的各种鱼类资源衰退,地理分布受到影响。

| Abstract: | Based on the Arcview GIS,the geographic distribution,biological characteristic of major economical and endangered fishes in upper Yangtze River region were analyzed as well as relevant biological environment and hydraulic architecture constructions of their habitats.It was found that human activity had serious impact on the ecological environment of upper Yangtze River,including hydraulic dam construction,over-fishing and contamination releasing.And it caused various highly adaptive fish resource collapse and changed the geographic distribution of migratory species. |
