摘要
西南岩溶地区地貌类型多种多样,受地貌特征控制岩溶地区地下水因缺少保护层而易受污染。本文以贵州清镇地区为例,在将该地区地貌特征进行分类的基础上,结合岩溶水二元补给性,试用"二元法"对其地下水抗污染风险性进行定性评价,并探寻不同岩溶地貌类型对地下水抗污染风险之间规律,结果显示在高石漠化地区与落水洞发育地区,如不加以保护,地下水极易被污染。通过与前人成果的对比,该方法以地貌特征直接判定地下水抗污染风险性,结果更直观明了,可通过高清影像图片进行初步判读,且本方法因数据量少,操作性强的特点,可在我国岩溶地区进行推广。
The southwest karst area landform types are varied. It is vulnerable to pollution due to lack of protective layer . In this paper, taking Qingzhen in Guizhou as an example, in the region geomorphology classification based on the combination of karst water recharge characteristics of binary trial ＂ dual method＂ of groundwater contamination qualitative performance evaluation Qingzhen region, and explore the law of different types of karst topography, groundwater pollution performance. The results show that, if not protected, high rocky desertification area of sinkholes developed , groundwater can easily be contaminated. This method is operational and requires less data. Its preliminary result can be interpreted by the high - definition video images. By contrast with the previous, according to topographical features directly determining the antifouling performance of groundwater , this method is more straightforward. It can be promoted karst areas in China.
