| 摘 要： | 从地下水脆弱性的胁迫应变关系出发,通过对西南岩溶区表层岩溶带发育机理和脆弱性特征的分析,提出了以表层岩溶带发育强度、保护性盖层厚度、补给类型、岩溶网络系统发育程度、土壤类型、植被条件、土地利用程度以及地下水开采程度8个胁迫因子(EPIKSVLG)作为对表层岩溶带水脆弱性进行定量评价的指标,并对各指标进行了详细的分析与分类,初步建立了表层岩溶带水脆弱性评价的指标体系。

| Abstract: | The development mechanism and the vulnerability characteristics of epikarst zone in Southwest China are analyzed according to the stress-response relation in ground water vulnerability. The EPIKSVLG method is selected to assess the ground water vulnerability of the epikarst zone. This method is based on a conceptual model of epikarst hydrogeological systems, which considers six epikarst system attributes and two human activity attributes: Epikarst development, Protective cover, Infiltration conditions, Karst network development, Soil self-purification, Vegetation, Land utilization and Groundwater exploitation. Moreover, each of these eight attributes is subdivided into classes. In this way, indexes of quantitative assessment of ground water vulnerability in epikarst zone are established. |
