摘　　要：利用土壤侵蚀综合指数对广东省土壤侵蚀现状数据进行区域分析。结果表明,广东省土壤侵蚀区域差异显著,总体为东北强西南弱,自然侵蚀较强的区域主要分布于花岗岩山地丘陵区和沿海、珠江三角洲丘陵区,人为侵蚀主要分布在经济发展活跃的珠江三角洲地区,以深圳、珠海、东莞为中心、遍及整个珠江三角洲,呈向东部沿海、东部山区和西部沿海区域发展的趋势。A comprehensive index is used to analyze the regional disparity of soil erosion in Guangdong province. The result shows regional disparity of soil erosion is distinct in Guangdong province as a whole, and erosion in the northeast is greater than in the northwest. Natural erosion occurs mostly in granitemountainoushilly regions and the Pearl river delta hill along the seashore in Guangdong province. Humancaused soil erosion is mainly in Pearl river delta region, where the economy is developing most actively. This includes Shenzhen, Zhuhai, Dongguan at the center and extends to eastern seashore, eastern mountains and western seashore gradually.
