基于模糊评价的拉萨河水环境现状分析

采用模糊评价模型对拉萨河水环境现状进行了评价。结果表明,在选取的10个监测断面中有6个监测断面水质属于Ⅰ类水体,且水体抗外界干扰能力较强;两个监测断面水质虽然属于Ⅰ类水体,但水体抗外界干扰能力较差,应加大监测频率;另有两个监测断面水质属于Ⅴ类水体,应加大DO和F-的监测频率并采取相应的治污措施。

Status Evaluation of Lhasa River Water Environment Based on Fuzzy Evaluation

Fuzzy evaluation model was used to estimate the current status of Lhasa River water environment. The results show that six monitoring sections are class Ⅰ waters and have stronger ability against external interference;and two monitoring sections are class Ⅰ waters, and the monitoring frequency should be increased because they have poorer ability against external interference. In addition, two monitoring sections are class Ⅴ waters, the monitoring frequency of DO and F~- should be increased, and pollution control measures should be taken.
