摘　　要：利用地下水动态监测、地下水开采量和流域径流量等资料 ,运用相关分析法 ,分析了三工河流域山前地下水库长期大量开采地下水引起地下水位逐年下降的原因 ,建立了地下水库开采量模型 ,并用水均衡法进行了验证 ,同时计算了不同保证率条件下三工河径流量相应的地下水可开采量。通过对灌区需水量的预测 ,提出了缓解本流域工农业需水量与流域水资源量之间的矛盾、合理利用地下水库的建议。Located in the Sangong River watershed in the southern marginal zone of Junggar Basin in the northern piedmont of the Tianshan Mountains, the study area is an irrigated area dominated by agriculture. There are 3 small streams with an annual runoff volume of 9.2222×10 7m 3 in the watershed. The exploitation and utilization level of the water resources in the watershed is rather high. When the exploitation and utilization of the surface water reached a saturation point, the exploitation of the groundwater began to be sharply increased, especially from the perimontane groundwater reservoir. In Fukang County of Xinjiang, the perimontane groundwater reservoir with an area about 140 km 2 and the fine storage conditions forms in the loose sand pebble gravel stratum composed of the connecting alluvial diluvial fans after the 3 small streams flow out of the debouchures, a great space of groundwater storage is provided, and the groundwater reservoir is steadily fed by permeation of the streams and rainfall. At present the annual exploited groundwater volume is 4.2273×10 7m 3 and is increased in an annual speed of 4.41×10 5m 3, whereas the groundwater level is lowered in an annual speed of 0.4 m, the drawdown funnel like areas appear in some regions, and some environmental problems occur. By using the data of the dynamical monitoring and the exploited volume of groundwater and the runoff volume in the watershed as well as the correlative analysis, in this paper the causes resulting in the drawdown of the groundwater level is analyzed, the models for determining the rationally exploited volume of groundwater are developed and verified by water budget method, and the exploitable volumes of groundwater under the different runoff conditions in the Sangong River watershed are calculated, which reveal that the present demand of water volume does not accord with the total volume of water resources in the watershed. By predicting the demanded water volume in the irrigated area, some suggestions are put forward for all
