| 摘 要： | 基于流域系统累积环境效应的产生机理，以系统动力学特征和累积环境效应-反应过程特征曲线为依据，分析了复合生态环境承载力及其适应性，提出并建立了非线性累积效应响应的指标阈值模型及因子响应程度的客观、动态量化方法。模型的建立对系统可持续发展的评估决策具有一定的指导作用。

| Abstract: | Based on the developing mechanism of cumulative environment effect, compound ecological environment capacity and systematic adaptation ability were analyzed aiming at system dynamic character and environmental characteristic effect-response curve. Index threshold value model on non-linear cumulative effect was advanced.At the same time the objective and dynamic factor quantification method reflecting response extent was set up. It is hoped to provide a certain theoretical direction for sustainable system appraisal and decision-making. |
