熵权属性识别模型在水库富营养化评价中的应用

水库富营养化评价中对各个指标进行权重分配时会遇到一定的人为主观因素的影响, 因此本算例对各指标权 重分配采用熵权法。选取广东省内的十座大型水库, 针对水库富营养化的问题选取六个指标并结合属性识别法建 立熵权属性识别模型。通过将计算得出的结果与这十座水库实际富营养化的情况进行比较, 发现计算结果与实际 情况基本一致, 由此可知熵权属性识别模型适用于水库富营养化程度的评价, 同时该模型简单, 具有一定的推广性。 Subjective factor s can affect the w eig ht distr ibut ion for each index in the evaluation of reserv oir eut rophicatio n, there2 fo re entro py metho d w as used to distr ibute the weig ht of each index .
