在总结土地利用与土壤侵蚀空间关系一般研究方法的基础上,引入并修正了土壤侵蚀强度综合指数和区域土壤侵蚀强度综合指数,对整个中国境内、辽河中下游地区、南水北调丹江口水库水源区湖北部分和广东省惠东县4个区域土地利用类型与土壤侵蚀强度空间关系进行了定量比较分析。结果表明:不同区域土地利用类型的土壤侵蚀序列各不相同,而同一区域不同时期土地利用类型的土壤侵蚀序列不确定;新出现的难利用地比长期闲置的难利用地土壤侵蚀发生率高;草地土壤侵蚀发生率偏高;耕地中旱地的土壤侵蚀发生率高;建设用地建设时土壤侵蚀强度大,而建成后土壤侵蚀强度小。
On the basis of summarizing the general research methods of spatial relationship between land use and soil erosion, the comprehensive index of soil erosion intensity and the comprehensive index of regional soil erosion intensity were introduced and revised. The comprehensive index of soil erosion intensity in the whole of China, the middle and lower reaches of Liaohe River, And the spatial relationship between land use type and soil erosion intensity in four regions of Huidong County, Guangdong Province. The results showed that the sequence of soil erosion of different types of land use was different, but the sequence of soil erosion of different types of land use in the same area was indefinite. The rate of soil erosion was higher than that of the fresh and hard - The incidence of grassland soil erosion is high; the incidence of soil erosion is high in arable land in cultivated land; the soil erosion intensity is great in the construction land construction and the soil erosion intensity is small in the grassland.
