干旱区地下水资源综合评价模式

通过2002~2004年新疆全疆地下水资源评价工作实践,提出了一套新的干旱区地下水资源评价模式。着重探讨了计算分区与面积的获取,水文地质参数的选取与处理,评价项的计算方法,评价成果的提取,以及评价方法和手段等。干旱区地下水资源评价模式结合G IS和RS技术对评价区进行区划,获取地下水资源评价计算面积,使评价精度大大提高;该模式系统合理地组织基础数据表、评价结果表、评价成果等之间的联系,应用现代计算技术以程序自动运行的方式进行计算,不仅节省了人力,而且提高了效率。该模式系统协调性强,程序模块化,应用方便,实用性强。

The Comprehensive Evaluation Mode of Underground Water Resources in Arid Area

Through the concrete practice of the underground water resources evaluation of Xinjiang from 2002 to 2004,this paper advance a set of new mode which can estimate comprehensively the underground water resources in arid area.This paper mostly discuss how to obtain subarea and area,how to select and deal with hydrogeologic parameter,how to compute the item of evaluation,how to distill achievement of evaluation and method of evaluation,and so on.The evaluation mode combines GIS and RS technique to partition the area of evaluation,in order to gain the account area of Underground Water Resources Evaluation.This mode can improve the precision consumedly.It organizes relation of basic datasheet,evaluation result sheet and achievement systemically and reasonably.Applying modern computer technical and through program auto run to compute,it not only save manpower,but also improve efficiency.This mode has strong system harmony,program modularized,application convenient and have strong practicability.
