中文摘要	粤北英德市岩背镇典型石漠化区在石漠化从轻度向极重度发展的过程中，土层厚度、土壤覆盖度和土壤有机碳含量均呈显著下降的趋势，土壤有机碳含量在石漠化初期下降幅度更大，而土层厚度、土壤覆盖度在石漠化发展的后期阶段下降程度更为明显；石灰岩植被随石漠化程度加重，向旱生和岩生方向演替，群落结构渐趋简单，植被盖度和现存生物量显著降低；除岩石裸露率与土层厚度、土被覆盖度、土壤有机碳、植被盖度和生物量都呈极显著的负相关关系外，其它各因子之间都呈显著性的正相关关系。
英文摘要	Yanbei Town of Yingde City in the northern Guangdong Province was selected as a typical site to investigate the soil and vegetation changes in the process of rock desertification. The results show that in the process of rock desertification from light grade to extreme high grade, the thickness of soil layer, the coverage of soil and the content of organic matter reduced significantly, the content of soil organic carbon reduced more in the primary stage of rock desertification than in the later stage, but the thickness of soil layer and the coverage of soil reduced more in serious stage than in the primary stage. The vegetation succession in the rocky area is towards xerophyte and rock plant in the process of rock desertification, and the structure of vegetation is getting more and more simple. The vegetation coverage and standing biomass reduced significantly. There exist significant negative correlations between the rate of uncovered rock and the thickness of soil layer, the coverage of soil, the content of organic matter, the vegetation coverage, and biomass. And there have significant positive correlations among other factors.
