基于盲数理论对吉林省白城地区月亮湖水库的水质评价

Water Quality Evaluation of the Moon Lake Water Pool in Baicheng Area of Jilin Province Based on Blind Number Theory

为了评价月亮湖水库的水质状态,考虑到水质环境的随机性、灰性等不确定性,将盲数理论应用于水质评价.在将指标盲数化后,建立了加权平均——盲数模型和改进的盲数可靠性模型.根据上述模型,利用月亮湖水库采样点的实测值就可以得到评价指标的各种可能值区间及相应可信度,从而确定月亮湖水库的水质为国家标准中的Ⅳ类等级.

In order to evaluate the water quality of the Moon Lake reservoir,the blind number theory is applied to water quality evaluation considering the uncertainty of water quality and environment. The weighted average blind number model and the improved blind number reliability model are established after the number blind number is counted. According to the above models,we can get all possible intervals and corresponding reliability of the evaluation index by using the measured values of the sampling points of the Moon Lake reservoir,so as to determine the water quality of the Moon Lake Reservoir as the category IV of the national standard.
