中文摘要	风水侵蚀交错带的研究，对景观、土地覆盖／土地利用，全球变化等研究具有重要意义。论文以GIS技术为支撑，定量计算出我国风水侵蚀带，在分布特征上，主要分布我国北方地区，其中以西部沙漠，北部山脉沿线为重，这种分布与气候，地貌分界有明显联系，49．6％风水侵蚀复合带的降水量小于200mm，风水侵蚀复合带的土地利用主要以草地为主，占41．8％，其次为耕地，两种类型的分布，草地以与其它土地利用类型交错分布为主；而耕地是有重心的分散分布。风水侵蚀复合带的总体侵蚀要强于全国水平
英文摘要	The study on the interleaving zones of water/wind erosion is of significance to the studies on the landscapes, land cover/land use, global change, etc. In this paper, the interleaving zones of water/wind erosion in China are calculated based on GIS. The results show that the interleaving zones of water/wind erosion are mainly distributed in north China, especially along the marginal zones of the desert in northwest China and of the mountains in north China. This kind of distribution is obviously related to the boundaries of climate and landforms. The annual precipitation in the interleaving zones occupying 49. 6 % of the total is less than 200 mm. Land use in the interleaving zones of water/wing erosion in China is dominated by grasslands (41.8% ), then by farmlands. For these two types of land use, the grasslands are interleaved with other types of land use, and the farmlands are decentralizedly distributed in some main regions. The general erosion in the interleaving zones of water/wind erosion is more serious than that of the average in China.
