【摘要】 利用VB语言编译常用的DRASTIC和AHP地下水脆弱性评价模型,并将编译的模型与地理信息系统结合,可以减少地下水脆弱性评价的工作量,实现评价结果的可视化。通过深入研究评价模型的公式和运算过程,用变量替换评价的指标值和权重,用程序语言编写模型的公式和运算过程,最终实现计算机代替人手工计算。基于计算结果,利用组件式地理信息系统MapObject开发的系统实现评价结果可视化。更多还原

【Abstract】 It can reduce the workload of groundwater vulnerability assessment,and achieve the Visualization of the results of the evaluation that the groundwater vulnerability assessment model,DRASTIC and AHP,are programmed with Visual Basic.The computing work of evaluation can realize with the computer,through the in-depth study of the evaluation formulae and the evaluation’s computing process,using variable replacement evaluation index value and weight,and using the programming language compile the formulae and the computing process.Based on the calculated results,the visualization of the assessment results can be achieved by the geographical information system components MapObject.更多还原
