GIS在地下水资源评价中的应用——以河西走廊黑河中游为例

本文以河西走廊黑河中游八灌区为例,利用ESRI公司的MapObjects开发的河西走廊水文地质信息系统(HXSIS)为平台,具体阐述了研究区内地下水均衡计算、地下水数值模拟、地下水资源评价及合理配置等与GIS的有机结合,对于改善地下水勘查的工作效率,提高水资源计算与评价精度,达到对水文地质实体的准确认识,分析河西走廊地下水资源开发利用潜力,评价与地下水资源开发利用有关的地质生态环境问题,具有重要的实际意义。

The closely-related combination of GIS in ground water resources evaluation——taking the middle reach of Heihe river in Hexi corridor as an example

For the great abilities of dealing with space data,the GIS provided new and original and efficient tools for groundwater resource management.This text setting the 8 irrigated areas of Heihe river in Hexi corridor and using the HXSIS developed by the Mapobjects of ESRI Company provides a more direct platform for the isostatic calculation expatiates numerical stimulation,water quality evaluation, resource evaluation and reasonable allocation of ground water in a specific way.And it has an important significance to raise working efficiency of prospecting groundwater and precision of groundwater resource calculation and evaluation,to realize the hydrogeologic entity and analyze the developing and using potentiality of groundwater resource in Hexi corridor,to investigate and evaluate ecological environmental problems about developing and using groundwater resource.
