摘要

该文计算了黄土高原南北水力侵蚀区、风蚀水蚀交错带及风沙边缘区的风蚀能量、水蚀能量及地形附加侵蚀能量。结果表明：在风水蚀交错带

在降雨侵蚀能量的基础上

由于风蚀能量的迭加

加之地形附加侵蚀能量也较高

使风蚀水蚀交错带成为黄土高原的高侵蚀能量环境区和潜在侵蚀强度较大的地区。随着向风蚀区的过渡

侵蚀能量逐渐增大。同时表明

下垫面条件的脆弱性是该区土壤侵蚀严重的根本原因。

Abstract

Crossing loess plateau from south to north·wind erosion energy water erosion energy and gravity erosion energy attached with terrain are calculated in water erosion region

wind water erosion region and wind erosion region.The results indicate that in wind-water erosion region

wind erosion energy makes up the decrease of water erosion energy

wind erosion energy

water erosion energy and gravity erosion energy attached with terrain make wind-water erosion region be an area of high erosion energy environment and potential erosion intensity. With transition from water erosion region to wind erosion region total erosion energy increases

especially wind erosion energy increases abruptly.Additionally

the results also show that the fragility of earth surface in wind一water erosion region is the main course of severe soil erosion in this region.
