摘要
通过对广西都安三只羊地区的岩溶发育特征、水文地质条件的分析,结果表明北部丁峒谷地一带,岩溶化程度较高,地下河发育,降雨入渗总量达13.2×106m3/a,水资源较为丰富;西南部岩溶发育相对较弱,溶洞发育规模不大,仅在局部地区见有表层岩溶泉水出露,水资源较为缺乏。水资源计算表明,全区水资源总量193.5×106m3/a,而现有开发量仅为3.2×104m3/a,因此还有较大的开发潜力。在总结水资源开发历史经验的基础上,提出了以堵、引与机井相结合的综合开采方式,以提高资源的利用率。
Through analyzing the karst development characteristics, hydrogeological conditions, it is found that the karstification degree is high and the subterranean stream is developed in Dingjiadong valley in the northern part of the area. The total amount of rainfall infiltration is up to 13. 2×10^6m^3/a, the groundwater resource is comparatively abundant. Karst development is weaker in the southwest area. The scale of cave development is small, only a few epikarst springs are revealed in some areas, so the water resource is comparatively poor. The total amount of water resource in the whole district is 193. 5×10^6m^3/a, but present developed amount is only 3. 2×10^4m^3/a,so the exploiting potential is great. On the basis of summarizing the historical experience of water resources＇ exploitation, in order to improve the utilization ratio of the resources, the integrative exploitation ways are cave blocking, water drawing and motor-pumped well.
