| 摘 要： | 地下水是岩溶山区现代城镇化发展的战略性基础资源，为了解城镇化进程中地下水资源功能的支撑作用，通过构建地下水资源功能评价指标体系，对贵州省9个市（州）岩溶区域城镇化进程中地下水的资源功能进行定量评价.评价结果表明:地下水的资源功能在城镇化进程中呈现明显的差异性特征，城镇化水平较高的贵阳市对地下水的依存性高达79.08%，地下水的资源功能较强；城镇化水平较低的地区对地下水的依存性较小，地下水的资源功能相对较弱.随着城镇化水平的提升，地下水资源的可持续性受地下水污染和超采等因素制约，其资源功能存在弱化甚至丧失的风险.

Evaluation on Resources Function of Groundwater during Urbanization in Karst Region of Guizhou Province |
| |
| Abstract: | Groundwater resources are basic strategic resources for the development of modern urbanization in karst areas. In order to understand the function of groundwater resources to support urbanization, an index system, Groundwater Resource Function Index, was used to evaluate groundwater's resources function during urbanization in 9 karst zones from Guizhou Province. The research results indicate that groundwater resourcs function varies significantly in response to different urbanization levels. The groundwater resources dependency is higher with stronger resources function in the regions of higher level of urbanization, for example, dependence on groundwater of Guiyang City is as high as 79.08%.Conversely, it is much lower. The sustainability of groundwater resources is impacted by over exploitation and contamination of groundwater, which may result in the weakening even the loss of the resources function of groundwater. |
