摘　　要：乐昌市是广东省岩溶地区石漠化程度最为严重的县市之一,岩溶区面积达76114.47 hm^(2),占土地总面积的比例为31.40%。全市17个镇(街道办)中有白石、庆云、梅花、沙坪、秀水、云岩、黄圃和坪石8个乡镇分布在石灰岩岩溶地区。通过对乐昌市石漠化监测,实时掌握监测区石漠化土地动态状况,分析石漠化土地动态变化原因,为往后石漠化综合治理提供数据支撑。Lechang City is one of the counties and cities with the most serious degree of rocky desertification in the karst area of Guangdong Province.The karst area covers an area of 76114.47 hectares,accounting for 31.40%of the total land area.Among the 17 towns(sub district offices)in the city,there are 8 towns and townships including Baishi,Qingyun,Meihua,shaping,Xiushui,Yunyan,Huangpu and Pingshi,which are distributed in limestone karst areas.Through the monitoring of rocky desertification in Lechang City,we can grasp the dynamic situation of rocky desertification land in the monitoring area in real time,analyze the causes of dynamic changes of rocky desertification land,and provide data support for the comprehensive management of rocky desertification in the future.
