摘要
粤北岩溶石山地区生态地质环境条件脆弱,成壤能力及水土涵养能力极低。岩溶分布区石漠化现象较为突出,并日益严重。全区现状石漠化面积为2 343.21km2,占碳酸盐类岩石分布面积的21.8%。本文根据该地区的水文地质与环境地质调查资料,结合遥感解译成果,研究了区内石漠化分布现状及其成因,并探讨石漠化现象及其发展对水环境的影响,为石漠化的综合治理规划提供了科学的资料和依据。
The eco-geological environment of the karst mountain area in northern Guangdong province is vulnerable. The capability of soil formation and water and soil conversation is quite low. The increasingly severe rock desertification phenomenon in the karst area is obvious. At present, the area of rock desertification, which covers 21.8% of the whole carbonate area, is 2343.13 km^2 . This paper analyzes the distribution and the cause of formation of the phenomenon in this area influence on the karst water environment. Thus, and gives a detailed discussion of rock desertification and its the work can provide scientific data for the ultimate control programming of the rock desertification.
