基于系统有序度熵的河流健康评判方法研究

Method of Evaluating River Health Based on System Order Entropy

河流系统是一个耗散结构,因此评价河流健康状况可以从系统的观点出发进行探讨研究。本文应用系统论和信息论的有关概念和理论,提出了基于系统有序度熵的河流健康评价方法,导出了综合考虑河流系统多个子系统(健康目标)的河流健康指标的数学表达。以黄河为例,分析提出了黄河健康因子,研究了各健康因子的阈值范围,评价了黄河现状的健康状况。

Since river system is of dissipative structure, evaluation of river health can be studied with systematic views. With system and information theories, this paper presented a method to evaluate the river health based on system order entropy. The river health indexes were educed with multiple subsystems or health targets of the river considered. The Yellow River was taken as an example, in which the river health factors and the concerned threshold parameters were analyzed, and the current health situation was evaluated.
