在新疆地下水资源评价工作实践的基础上,本文探讨和归纳了3S与VBA技术在区域地下水资源评价中的应用。首先,阐述了GPS、RS、GIS两两之间结合应用于提取遥感信息、区划评价类型区、划定计算分区,进而构建基础数据库、展现评价结果等的技术方法。同时。概述了以Excel作为工作平台结合VBA编制程序实现计算方法的程序化和计算步骤的自动化的基本流程。然后,简述了新疆地下水资源评价中的实例应用,最终行之有效地取得了令人满意的评价结果。评价得到新疆近期地下水开采潜力约为66.2×10~8m~3。
Based on the practice of groundwater resources evaluation in Xinjiang, this paper explores and summarizes the application of 3S and VBA technologies in regional groundwater resources assessment. First of all, the technical methods of combining GPS, RS and GIS, which are used to extract the remote sensing information, partition the evaluation type area, demarcate the calculation partition, construct the basic database, and display the evaluation result are described. Simultaneously. In this paper, the basic procedure of automation of program and calculation steps of computing method with Excel as a working platform and VBA programming is summarized. Then, the application of examples in groundwater resources evaluation in Xinjiang is briefly described, and finally a satisfactory evaluation result has been obtained. Evaluation of Xinjiang’s recent groundwater exploitation potential of about 66.2 × 10 ~ 8m ~ 3.
