广东岩溶地区石漠化动态变化与原因分析

摘要

According to the results of two monitorings, the monitoring karst area of Guangdong Province is 1 063 060.4 hm2, of which the stable area 1 023 342.3 hm2, accounting for 96.3% of the monitoring karst area, the succession area 31 479.7 hm2, accounting for 3.0% of the monitoring karst area, reverse succession area 8 238.4 hm2, accounting for 0.7% of the monitoring karst area. The dynamic changes in the karst area and the dynamic changes in the rocky desertification land of Guangdong Province were investigated, and the reasons for the changes were explained.%根据两次监测的结果,广东省岩溶区监测面积1063060.4 hm2,其中稳定型面积1023342.3 hm2,占监测区岩溶面积的96.3％,顺向演替面积31479.7 hm2,占监测区岩溶面积的3.0％,逆向演替面积8 238.4 hm2,占监测区岩溶面积的0.7％；对广东省岩溶地区石漠化状况及程度之间的动态变化做了分析,并对变化原因进行了解释.
