摘要
通过分析哈密盆地近20 a来地下水埋深、多年地下水开采量等资料,借助GIS得出近20 a来哈密盆地内地下水埋深变化趋势。结果表明,由于农业用水量比重太大,用水结构长期失衡,盆地北部冲洪积平原以及中部农业灌区地下水埋深显著增大。盆地内农业用水量居高不下的根本原因是耕地面积的不断增长,必须限制并减少耕地面积才能最终解决长期以来制约哈密盆地地下水资源可持续利用的根本问题。
The data of groundwater depth and the pumping yield in the past 20 years in Hami Basin had been analyzed, and obtained the trends of the groundwater in Hami Basin by GIS. The result shows that the groundwater depth fell down sharply in the past 20 years, especially in the farming region in the middle area to the alluvial-pluvial plain near the north edge of the basin where the exploitation of the groundwater is overloaded serious- ly. Agriculture a.s the largest consumer of the water resources has caused the imbalance of water consumption for years. And the solution to nmintain sustainable utilization of the limited water resources is to decrease the acreage of farm land which is increased continuously in the past 20 years.
