摘要
以深圳市赤坳水库为例,利用可变模糊模型对水库水质进行评价。根据水库特点选取8个水质评价指标,建立指标体系,然后利用二元比较理论确定指标权重,计算模型相对隶属度,从而得到水库水质评价结果。评价结果表明,赤坳水库水质介于Ⅰ类水和Ⅱ类水之间,居于良好使用水平,能够满足供水对象的用水要求。研究表明,可变模糊模型在水库水质评价中具有良好的可行性和实用性。
The variable fuzzy model was used to evaluate the water quality of the Chi’ao Reservoir .According to the characteris-tics of the reservoir ,eight water quality evaluation indexes were selected to construct an index system .The two element theory was applied to determine the index weight and calculate the relative membership degree of the model ,thereby providing the wa-ter quality evaluation results .The results showed that the water quality in the Chi’ao Reservoir is between class I and class II , water utilization is at its good level ,and water supply can meet the requirements of users .The variable fuzzy model is feasible and practical in evaluation of reservoir water quality .
