Intensification of agricultural systems may result in overexploitation of water resources in arid regions because enhanced productivity of crops is often associated with increased actual evapotranspiration (AET). The aim of this study was to quantify the effect of increased regional AET on the groundwater level in a case study of the oasis located within the Shiyang River Basin near the edge of the Gobi Desert. The results of the study show that regional AET increased during the period from 1981 to 2010 due to increasing oasis area and air temperature. The water losses due to AET exceeded the water supply from the mountainous discharges of the basin by the end of this period, leading to groundwater overexploitation in the oasis area. This case study shows the importance of considering the effect of climate change on water losses associated with increasing agricultural production for the sustainable agricultural development of arid regions.

提高土地生产力对地下水动力学的影响：以戈壁沙漠边缘的绿洲为例。

农业系统的集约化可能导致干旱地区水资源的过度开发，因为农作物的生产力提高通常与实际蒸散量（AET）增加有关。这项研究的目的是，以戈壁沙漠边缘附近的石羊河流域内的绿洲为例，量化增加的区域AET对地下水位的影响。研究结果表明，由于绿洲面积和气温的升高，区域AET在1981年至2010年期间有所增加。到这一时期结束时，由于AET造成的水损失超过了流域山区排水的供水量，导致绿洲地区的地下水过度开采。
