| 摘 要： | 甘肃省地处我国西北内陆,地下水资源匮乏,水资源供需矛盾突出,查明地下水资源大账显得十分必要。本文在全面收集和分析以往不同时期水文地质勘查及研究成果基础上,按不同水文地质单元、行政区划、地貌单元较系统地总结了各区地下水资源量,简要分析了开发利用状况。结果表明,甘肃省地下水天然补给资源量132.79×108m^3/a。其中,内陆河流域51.80×108m^3/a,黄河流域47.07×108m^3/a,长江流域33.91×108m^3/a;西部地区57.86×108m^3/a,东部地区20.97×108m^3/a,南部地区53.95×108m^3/a;山区80.98×108m^3/a,平原区51.80×108m^3/a。全省现有地下水开采机井约3.5×104眼,地下水开采量26.2×108m^3/a,地下水可开采资源量53.89×108m^3/a。西部地区开发利用程度较高,尤其是石羊河的民勤县地下水严重超采。东部和南部地区开发利用程度较低。

| Abstract: | Gansu Province is located in inland of Northwest China,the groundwater resource is scarce,the contradiction between water supply and demand is obvious and identify a large loss of groundwater resources very necessary.The comprehensive collection and analysis of the different periods of the past exploration and hydrogeology based on research results,according to different hydrogeological unit,administrative division,geomorphic units systematically summed up the amount of groundwater districts,a brief analysis of the development and utilization conditions.The results show that the natural recharge of groundwater resources in Gansu Province,the amount of 132.79 × 108 m3 / a.Among them,the inland river basin 51.80 × 108 m3 / a,the Yellow River Basin 47.07 × 108 m3 / a,Yangtze River 33.91 × 108 m3 / a;West 57.86 × 108 m3 / a,eastern region 20.97 × 108 m3 / a,south 53.95 × 108 m3 / a;Mountain 80.98 × 108 m3 / a,plain 51.80 × 108 m3 / a.Existing groundwater wells across the province about 3.5 × 104 eyes,groundwater exploitation 26.2 × 108 m3 / a,the available groundwater resources 53.89 × 108 m3 / a.Higher degree of development and utilization of the western region,especially the over-exploitation of groundwater in Shiyang of the Minqin county.the lower development level in the Eastern and southern parts of is low. |
