中文摘要	在粤北石漠化地区选取不同石漠化阶段的样地,对其碳酸盐岩进行室内岩性溶蚀和野外模拟溶蚀试验,研究不同石漠化阶段碳酸盐岩溶蚀特点。结果表明:在轻度中度重度极重度石漠化演化过程中,重度石漠化阶段是碳酸盐岩溶蚀变化的一个重要转折点,在这个阶段中,溶蚀过程从以化学溶蚀转为物理侵蚀为主。不同石漠化阶段不同环境中的碳酸盐岩溶蚀速度在地上50cm处,轻度石漠化土地>中度石漠化土地;在地面0cm处,极重度石漠化土地>重度石漠化土地>轻度石漠化土地>中度石漠化土地;在地面下10cm处,极重度石漠化土地>轻度石漠化土地>中度石漠化土地>重度石漠化土地;在地面下20cm处,轻度石漠化土地>中度石漠化土地>重度石漠化土地;在地面下30cm处,轻度石漠化土地>中度石漠化土地。
英文摘要	Some plots were selected in rocky desertification area in North Guangdong to study the corrosion characteristics of carbonate rocks in different stages of rocky desertification through laboratory and field experiments. The results showed that:The severe stage of rocky desertification was a very important turning point of dissolution of carbonate rocks in different stages of rock desertification,and in this stage,the main process of dissolution of carbonate rocks was physical erosion instead of chemical corrosion.The dissolution speed of carbonate rocks changed with different environments and different stages.At 50 cm above the ground,the speed of slightly rocky desertified land was bigger than that of moderately rocky desertified land.At 0cm on the ground,the descending order sorted by dissolution speed was very severely rocky desertified land,severely rocky desertified land,the slightly rocky desertified land,the moderately rocky desertified land.At 10 cm underground,the descending order was the very severely rocky desertified land, the slightly rocky desertified land,the moderately rocky desertified land,the severely rocky desertified land.At 20 cm underground,the descending order was the slightly rocky desertified land,the moderately rocky desertified land,the severely rocky desertified land.At 30 cm underground,the speed of slightly rocky desertified land was bigger than that of moderately rocky desertified land.
