摘要

世界上干旱和半干旱地区的面积正在增加;为解决干旱半干旱区浅层地下水富集评价的相关问题，以甘肃武威西民秦县典型干旱半干旱区为研究区，通过遥感，以GF-6、CBERS04和DEM为数据源，采用分层分析法，构建分层富集结果评价模型。获得了研究区近5年及未来5年浅层地下水分布规律。近5年水位分布趋势基本一致，由西南向东北逐渐降低，存在多个地下水通道，未来5年浅层地下水含量将保持稳定并略有增加。研究结果评价了甘肃武威市浅层地下水的发展趋势;为今后浅层地下水管理提供了科学依据。

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

: 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.

期刊介绍： IEEE Geoscience and Remote Sensing Letters (GRSL) is a monthly publication for short papers (maximum length 5 pages) addressing new ideas and formative concepts in remote sensing as well as important new and timely results and concepts. Papers should relate to the theory, concepts and techniques of science and engineering as applied to sensing the earth, oceans, atmosphere, and space, and the processing, interpretation, and dissemination of this information. The technical content of papers must be both new and significant. Experimental data must be complete and include sufficient description of experimental apparatus, methods, and relevant experimental conditions. GRSL encourages the incorporation of "extended objects" or "multimedia" such as animations to enhance the shorter papers.
