基于未确知测度模型的漓江水质综合评价

Comprehensive Evaluation on the Water Quality of Lijiang River Based on the Unascertained Measure Model

采用未确知测度模型对漓江水质进行了综合评价。结果表明,漓江兴安段水质为Ⅰ水体,灵川段和阳朔段为Ⅱ水体;在水质评价中,DO、氨氮和总磷具有重要的权重。未确知测度模型对评价空间实现有序分割,提高了分辨率,评价效果可靠,是一种实用模型。利用未确知测度模型对漓江水质进行的综合评价,结果更加准确客观,具有一定的理论意义和实用价值。

The water quality of Lijiang River was comprehensively evaluated by using the unascertained treasure model, rune results showed that the water quality of Xing＇ an section was Class Ⅰ and that of Lingchuan section and Yangshuo section were Class Ⅱ. DO, ammonia nitrogen and total P had important weights in the evaluation of water quality. Tne ordered partition of the evaluation space was realized by using the unascertained measure model. The resolution was improved and the evaluation effects were reliable. So the unascertained measure model was a kind of practical model. The comprehensive evaluation on the water quality of Lijiang River by using the unsscertained measure model obtained the more exact and objective results, with certain theoretical significance and practical values.
