A Primary Study on Fish Geographic Distribution in Upper Reach of Yangtze River Based on GIS
Based on the Arcview GIS, this study analyzed the geographic distribution, biology characteristic of major economical and endangered fishes in upper reach of Yangtze River, as well as chemical factor, relevant biology environment and hydraulic architecture constructions of their habitats. It was found that human activity had serious impact on the ecological environment of upper reach of Yangtze River, including hydraulic dam construction, over-fishing, contamination releasing, and it led to various fish resource collapse and the geographic distribution of migratory species change.
