摘　　要：喀什市是一座典型的沙漠绿洲城市,水生态环境相对脆弱。而喀什经济区及周边县市均属于水质缺水地区,地下水水质部分超标,为查明该区域地下水流动系统具体变化特征,首先对研究区地下水流动系统进行划分,同时也对地下水位空间变化特征进行分析,最终研究结果表明:喀什经济开发区第四系含水层系统中的地下水由补给区向排泄区流动,沿着水流路径,地下水化学成份发生着有序演化,是一个完整独立的具有统一时空演变过程的地下水体,每一个地下水流域,就是一个地下水流动系统。研究区中部存在东西向展布的地表水和地下水的分水岭,可将研究区第四系地下水流动系统分为北部克孜勒河和南部盖孜河两个地下水流动亚系统。Kashi is a typical desert oasis city.Its ecological environment is relatively fragile.Both Kashi and its neighboring counties and cities belong to water-scarce areas,and the quality of groundwater is partly exceeded.In order to find out the changing characteristics of groundwater flow system in this area,the groundwater flow system in the study area is divided and the spatial variation characteristics of groundwater table are analyzed.The final results show that the groundwater in Quaternary aquifer system in Kashi Economic Development Zone is flow from the recharge area to the discharge area.Along the water flow path,the groundwater chemical composition undergoes an orderly evolution and is a complete and independent groundwater body with a unified temporal and spatial evolution.Each groundwater basin is a groundwater flow system.There is an east-west distribution of surface waters and groundwater watershed in the central part of the study area.The Quaternary groundwater flow system in the study area can be divided into two sub-systems of groundwater flow in the northern Kizil and the southern Gaizi.
