Cumulative Environment Effect Analysis of Water Exploitation Based on Compound Ecosystem

摘要

Based on the principle of sustainable environment and economic development of basin, the cumulative environment effect of compound ecosystem on basin water resources exploitation is analyzed aiming at the carrying capacity, adaptation ability of ecological environment, the ecosystem non-linear dynamic character and its typical cumulative environment effect-response curve. Meanwhile an assessment pattern of sustainable basin system is set up and a kind of factor quantification method that reflects cumulative effect and ecosystem threshold value character is preferred. They set up a certain theoretical foundation for the compound basin ecosystem research, environment influence assessment and decision-making.
