China Finds 14,000-Km Underground Rivers in Rock Desert Areas
China finds 14,000-km underground rivers in rock desert areas
BEIJING, Sept. 29 (Xinhua) -- A newly conducted geological survey has found more than 3,000 underground rivers with a total length of 14,000 kilometers in southwest China's rock desert areas.
These underground rivers account for 70 percent of the total underground water in the rock desert areas, which is a valuable resource for future development, the report said.
China's rock deserts are mainly in the karst erosion areas in southwestern provinces of Guizhou and Yunnan and the southern Guangxi Zhuang Autonomous Region. In these areas, surface water easily leaks through the carbonate terrane, leaving the land dry and leading to rock desertification.
The report suggested the government adopt more effective ways to stop the expanding of rock desert areas.
