将GIS与专业计算地下水运动的FEFLOW模型结合,建立地下水模型预测不同土地利用模式对干旱区绿洲地下水资源的时空分布产生的影响.研究区域选取三工河流域绿洲区,模型模拟显示绿洲上部主要城镇聚居区地下水位逐渐下降,下部地下水位呈现缓慢上升趋势.耕地作为显著变化的土地利用类型,成为影响区域地下水资源的决定性因素.

By combining GIS with and TEFLOW of a special software modeling groundwater flow, the paper established groundwater model and studied the influence of land used on temporal-spatial distribution of grounel watrer resources. Taking an oasis of Sangong River Watershed as a study case, the result showed that the groundwater table in upper of the oases went into descent and the groundwater table in the down part of the oases slowly ascended. The cultivated land as a type of land use was a decisive influence factor on the groundwater table in the area.
