The problem of karst rocky desertification caused by soil loss is very serious in some karst areas of southwest China. The cycle process of rainwater–surface water–underground water controls the direction and trend of soil surface loss and underground leakage in karst rocky desertification areas. In this paper, Guanling–Huajiang plateau canyon rocky desertification area is the study area, and the water chemistry and stable isotopic characteristics of the karst water system in the study area were obtained by field investigation, hydrochemical and isotopic analysis of sampling water. The hydrogeological environment and lithology of karst springs' supply stratum were analyzed, and the supply elevations of main karst springs were estimated. Finally, the supply direction and scope of the main karst springs in the study area were inferred. The results reflected the characteristics of the groundwater flowing direction and the supply law of karst springs, and provided a theoretical basis for future research on the trend of soil surface loss and underground leakage in karst rocky desertification areas.

贵州关岭—花江石漠化区岩溶泉水源分析

西南部分喀斯特地区因水土流失造成的喀斯特石漠化问题十分严重。雨-地表水-地下水循环过程控制着喀斯特石漠化地区地表流失和地下渗漏的方向和趋势。本文以关岭—花江高原峡谷石漠化区为研究区，通过野外调查、采样水的水化学和同位素分析，获得了研究区喀斯特水系统的水化学和稳定同位素特征。分析了岩溶泉补给层的水文地质环境和岩性，估算了主要岩溶泉的补给高程。最后推断了研究区主要岩溶泉的供应方向和范围。
