摘    要:针对华北地区严重的地下水超采问题,选取河北境内的滹沱河、滏阳河、南拒马河3条补水河道的试点河段开展地下水回补效果评价。采用层次分析法,建立了包括入渗回补率、地下水水位回升率、水质改善度、水面面积变化率、水生态改善度和公众满意度等6项指标的地下水回补效果评价指标体系;选择简便实用的指标计算方法对河段补水前后指标的变化进行计算分析,并对生态补水的效果进行评价分级。结果表明:补水结束时,滹沱河、滏阳河、南拒马河3条试点河段的平均入渗回补率为65%,地下水水位相对回升率为分别为36%,17%,6%,水质改善度依次为51%,34%,90%,水面面积总计增加了8.56 km2,水生态改善度依次为46%,87%,94%,公众满意度分别为90%,90%,80%。利用建立的地下水回补效果评价方法计算滹沱河、滏阳河、南拒马河综合得分分别为84,47,64分,评价等级分别为"非常好" "一般" "较好"。3条试点河段评价结果与实际补水效果基本一致。

Abstract:In view of the serious problem of groundwater overdraft in North China, the experimental river sections of Hutuo River, Fuyang River,and Nanjuma River in Hebei Province were selected to evaluate the effect of groundwater recharge. The evaluation index system of groundwater recharge effect was established by selecting indexes from the six aspects of groundwater level recovery rate, water surface area change rate, water quality improvement degree, water ecology improvement degree,and public satisfaction degree. With AHP,a simple and practical index calculation method was selected to calculate and analyze the changes of indexes before and after the river reach replenishment, and finally to assess the effect of ecological replenishment. The results show that at the end of the groundwater recharge, the average infiltration rate covering the three pilot sections of Hutuo River, Fuyang River,and Nanjuma River is 65%, the relative recovery rate of groundwater level is 36%, 17%, and 6% respectively, the degree of groundwater quality improvement is 51%, 34%, 90% respectively, the water surface area is increased by a total of 8.56 km2, and the water ecological improvement degree is 46%, 87%, 94% respectively. In addition, the public satisfaction is 90%, 90%, and 80% respectively. The comprehensive assessment score of Hutuo River, Nanjuma River, and Fuyang River is 84, 64,and 47, respectively, and the corresponding evaluation grade is "very good" "good", and "normal", respectively. This results of the three pilot river sections are basically consistent with the actual water replenishment effect.
Keywords:groundwater  recharge  analytic hierarchy process  index system  effect assessment
