摘　　要：该文在新疆阿图什哈拉峻地区地下水系统模型识别的基础上，合理选择水文地质参数，建立了地下水预报、预测模型，对三种设计开采量：在2001年现状开采2779．65×10^4m^3／a的基础上增加250×10^4m^3／a、2000×10^4m^3／a、4000×10^4m^3／a进行了连续10年地下水水量、水位开采变化预报，结果比较显示：第一种方案新增开采量较小，10年间引起的水量、水位变化不明显；后两种方案地下水位将不断下降，与之相关的蒸发量和泉溢量都逐年减少，但总的趋势不断减缓，第十年仅动用储存量变化量94．4×10^4m^3和103．2×10^4m^3，水量变化基本达到稳定。10年累积平均水位降为0．46m和1．008m，随着水量逐渐趋于平衡，第十年间平均水位降仅为1-2cm，虽然开采期末的水位降还要大一些，但在开采期后会得到较大恢复，与研究区地下水资源储量丰富相符。随开采量的增加，降落漏斗不断扩大，降落漏斗区正好位于新增开采区处，与预计结果相符，进一步验证了模型的正确性和适用性。The prediction model of groundwater system of Halajun was established by selecting hydrological geologic characteristic parameter reasonably. Under three-design exploitation quantity which is added 250 × 104 m^3/a .2000 × 104m^3/a . 4000 × 104 m^3/a to actuality exploitation quantity in 2001 （2779.65 × 104 m^3/a ） respectively , the change of groundwater quantity and water level were predicted after exploitation in sequential 10 years. The results showed that the changes of the groundwater quality and water level were non-obviouse in the first plan. The water level fall down continually and evaporation quantity , spring overflow quantity would decrease year after year in the later other two plans, but the general trend became slower. The using of store variables are only 94.4 × 104 m^3 and 103.2 × 104 m^3 in the tenth year, the change of water quantity reach stable on the whole. The cumulate descending quantities of average water lever are 0.46 m and 1. 008m, it was only 1- 2 centimeter along with water quantity gradually tend to balance during the tenth year. Although water level fall was bigger at the end of exploitation period, it would be renewed after exploitation period, which accords to the fact that the groundwater reserves were abundance. Descended tundishs enlarge gradually following increasing of exploitation quantity and they mainly lie in new exploitation region, this result accord to assume result. All these validate the correctness and applicability of this model.
