【 摘 要 】

Based on groundwater remote sensing fuzzy assessment index (GRSFAI), a research on groundwater enrichment in the arid gobi region in the southeast of Yanqi basin in Xinjiang was carried out. In consideration of the sources of groundwater, storage space and runoff conditions, remote sensing interpretation and DEM data analysis methods were adopted to extract 6 factors related to the groundwater enrichment, such as lithology, fault, relief, slope, vegetation coverage, flow accumulation. Each factor which was quantified by fuzzy comprehensive method would be calculated by AHP, and the rapid delineation of groundwater enrichment area was finally realized according to the weighted calculation results. On the basis of the research, two wells have been constructed in the groundwater enrichment area, which has water yield of 3500m3/d and 3800m3/d respectively. The reliability and applicability of the GRSFAI method to evaluate the groundwater enrichment in research area are also validated.
