Eco-environmental Carrying Capacity of Water in upstream of Liao River Basins, China

摘要

Eco-environmental carrying capacity of water comprehensively representing the resource and eco-environmental characteristics of water determines the carrying ability of nature ecosystem for socio-economic development. Fushun and Tieling section are chosen as upstream in Liao River Basin to compare the eco-environmental carrying capacity of these two water stream. In this paper, 11 indexes are selected to establish evaluating indicator system, and then use the fuzzy comprehensive evaluation method to calculate eco-environmental carrying capacity of water. Result demonstrated: the score value of water eco-environmental carrying capacity of Fushun section is greater than that of Tieling. The little advance of water eco-environmental carrying capacity of Fushun was due to its better nature eco-environment.
