基于熵理论的河流水环境评价及应用

在经济社会不断发展的今天,环境问题越来越突出,分析和评价环境问题已经不能仅从单一角度进行,而是要从综合、系统的角度来对待,引入系统熵理论,通过结合熵理论的指标值权重求解方法和协调度的指标达标计算方法来建立河流水环境评价模型,并以深圳市龙岗河2007年4个监测点全年水质平均监测数据为算例对该区域的河流水环境进行评价,得出龙岗河上游水质优于下游水质,以及沿河排污、中游污水处理工程对水质变化的作用,探讨该方法的可行性。

Application of Water - Environmental Evaluation in Theory of Entropy

With the development of economy and society, the problem of environment is more and more prominent. The paper established an evaluation model of water environmental based on the theory of entropy and computation of coordination level. The data from seven water quality monitoring stations on Longgang River in 2007 was selected to discuss the feasibility of this method. The result show that the water quality on upstream is better, but with influence from pollution discharges and sewage treatments.
