摘要
为了进一步验证GRSFAI的有效性和普适性,为下一步实现地下水富集性自动化提取技术提供技术理论支撑,充分利用地下水资源以及有效的给水保障提供参考依据,选择西藏阿里地区及周边区域作为研究区,采用GRSFAI分析方法对该研究区的浅层地下水富集性展开研究。研究得到研究区内一级、二级、三级富水区面积分别为495 km2、1511km2、4542 km2,各占总面积的2.8%、8.5%和25.4%,该结果并在最具代表意义的一级富水靶区狮泉河区域得到了实地调查验证。分析认为:GRSFAI能较好地反映地下水富集程度,利用该指数对地下水富集性进行评估是可靠的,并具有良好的普遍适用性。
To further verify the effectiveness and universality of GRSFAI,provide theoretical support for the realization of the technique to automatically extract groundwater enrichment and provide reference for the full use of groundwater and effective water supply in war,the shallow groundwater enrichment in Ali in Tibet and its peripheral area are examined with the GRSFAI analysis method. The area of the three levels are 495,1511,4542 km2,respectively,with the percentage of 2. 8%,8. 5% and 25. 4%. The Shiquan River region with the level A enrichment zone is investigated to verify the results. The analyses show that GRSFAI can effectively reflect the groundwater enrichment. The reliability and universal applicability of the index for evaluating the groundwater enrichment are also validated.
