| 中文摘要:西南岩溶地区面积78万km2,地下水系统包括裸露岩溶水系统和覆盖-埋藏型岩溶水系统两大类。由于降水丰富、地下岩溶发育,西南岩溶地下水资源丰富,在43万km2调查区内,具有地下水天然资源量1762.82×108m3/a,岩溶地下水允许开采资源量615.70×108m3/a。近年来,通过开展水文地质调查,在地下河、表层岩溶水和蓄水构造岩溶水打井开采方面均取得重要进展,产生了显著的经济和生态环境效应。但由于西南地区岩溶水开发难度大,区域经济落后,西南岩溶地下水的开发利用程度普遍较低,已开采量为98.32×108m3/a,仅占允许开采量的15.97%,剩余地下水潜力资源量517.38×108m3/a。 |

| The Application Effects and Exploitation Capacity of Karst Underground Water Resources in Southwest China |

| Abstract:There are about 780,000 km2 karst areas in southwest China, which are composed of two types of underground water systems, i.e., the bare karst water system and the covered-buried karst water system. With a lot of rainfall and the well developed underground karst forms, there exist abundant karst underground water resources in southwest China. In the geological survey area of 430,000 km2, the natural resources of underground water amount to some 1762.82×108 m3/a, and the allowed exploiting quantity of underground water reaches 615.70×108 m3/a. In recent years, with the performance of the hydrogeological survey, the exploitation of the underground river, epi-karst water and karst water in storing water tectonics has made an important advance and created evident economic and ecological effects. However, due to the difficult exploitation conditions of karst water and the relatively backward regional economy, the exploiting degree of the karst underground water in Southwest China is on the whole rather low. So far, the total exploiting quantity is 98.32×108 m3/a, only occupying 15.97% of the allowed exploiting quantity. There remains an exploiting capacity of the karst underground water resources for about 517.38×108 m3/a. |
