地下水环境承载力是水环境承载力研究的重要组成部分, 是衡量人类社会经济发展与区域水环境协调程度的 判别依据。以内蒙古自治区准格尔旗为研究区, 建立地下水环境承载力评价体系, 并利用层次分析法( AH P) 判断 矩阵确定各指标的权重值, 进行研究区地下水环境承载力评价。结果表明, 准格尔旗地区地下水环境承载力在0. 308 3~ 0. 731 1 之间, 平均为0. 521 5, 属于中等偏弱程度。评价结果与研究区水文地质条件和社会经济发展现状 基本吻合, 可为准格尔旗在未来工业化进程中地下水资源管理和地下水环境保护决策提供依据。

Gr oundw ater envir onment car ry ing capacity is an im po rtant component o f the r esea rch in wat er envir onment ca rr ying capacity , and it can be used to characterize the harmonio us deg ree between the economic development and r egio na l w ater env i2 r onment. In o rder to ev aluate the gr oundw ater environment ca rr ying capacity in Zhung eer Count y, we have adopted a w ell2 know n met ho d of analy tic hierar chy pr ocess ( AH P) to build up the index sy stem, which consist s o f the natur al indexes and so2 cial index es. The index es include the t opog raphic slo pe, aquifer thickness o f g ro undw ater, g ro undwater lev el, nature o f unsatu2 r ated zone, hydr aulic conductiv ity, po pulation densit y, the per ca pit a GDP, cr ops sow n area, water consumptio n per 10000 yuan GDP, and per capita g roundw ater ex plo itatio n. AH P matrix met ho d was used to determ ine the w eight for each index . The re2 sults show ed that the numer ical gr oundw ater environmental car ry ing capacity in Zhung eer County is between 01 308 3 and 01 731 1 w ith an av erag e v alue of 01 521 5, w hich belong s to t he moderately w eak degr ee. The ev aluatio n r esults w ere consistent wit h the hydro geo log ical co ndit ions and socio2econom ic development in the study ar ea, w hich sugg ested that the study can pro2 v ide a t heo retical basis for t he g roundw ater r eso ur ces management and gr oundw at er env ir onment prot ection decisio ns in the fu2 tur e o f the industria lizatio n pro cess in Zhung eer County.
