| 摘 要： | 石羊河流域位于甘肃省河西走廊东部，由于气候变化和流域内工农业生产的发展，流域内径流减少，地下水大力开采，导致流域内各地的地下水水位下降，近20 a来，流域内民勤县最大地下水水位平均下降速率达0.57 m/a。分析了流域内地下水水位下降的分布情况和原因。要防止地下水水位继续下降，保证流域社会经济可持续发展，需采取关闭部分机井、发展节水高效农业、工程调水补充地下水等措施。

| Abstract: | Shiyang River Basin is located in the Gansu Corridor. Due to climate variation and industrial and agri-cultural development in the basin,the basin runoff reduced. Excess development of underground water resulted in under-ground water level drop in the basin,in recent 20 years,the maximum underground water drop rate in Minqin county reaches 0. 57m/a. This paper analyzes the distribution and causes of underground water level drop. To prevent succes-sive drop of underground water level and guarantee the sustai... |
