Research on Shallow Groundwater Enrichment Assessment Based on RS and GIS Arid and Semi-Arid Areas

Abstract

: The area of arid and semi-arid areas in the world is increasing; in order to solve the issues related to the shallow groundwater enrichment assessment of the arid semi-arid areas, take the typical arid and semi-arid area as the research area of Wuwei Citizen Qin County, Gansu, through remote sensing, GF-6, CBERS04 and DEM are used as data sources to use layer analysis to build an evaluation model for hierarchical enrichment results. It has obtained the laws of shallow groundwater distribution in the research zone in the past five years and the next five years. The trend of water level distribution in the past five years is generally consistent, showing from the southwest to the northeast gradually decreases, there are multiple groundwater funnels, and the shallow groundwater content will remain stable and will increase slightly in the next five years. The results of this study evaluate the development trend of shallow groundwater in Wuwei citizens in Gansu; it provides a scientific basis for future shallow groundwater management.
