改进的未确知测度评价模型在水环境质量评价中的应用

构筑了一种新的单指标未确知测度模式,在此基础上建立了改进的未确知测度模型,并应用该模型对某经济开发区的水环境质量状况进行了评价.结果表明,改进的未确知测度模型的样本排序与样本识别所得的判断结果相吻合,避免了传统未确知测度模型在固有的情况下,样本排序与样本识别判断不一致的问题,从而能够更加客观、合理地反映水环境质量状况.

Application of Improved Unascertained Measurement Model in Water Environmental Quality Assessment

In this paper, a new single-indicator unascertained measurement model was built up, on the basis of which the improved unascertained measurement model was established and the model was used to assess water quality of one economic development zone . The results show that the sample sequencing of improved unascertained measurement model is in accordence with the judgment results of sample identification to avoid the inconsistent of sample sequencing and sample identification by traditional unascertained measurement assessment model in the inherent circumstances ,which can reflect the water quality objectively and reasonably.
