摘 要：
The dune area in the northwest Shanxi Province, is an area developing into desert. The wind erosion occours mainly in spring when the great majority of gales within a year occur, meeting with droughts and naked farmland, which has caused intensive wind erosion on the farmland with erosion modulus of 12780 t/km~2. Vegetation is greatly effective in preventing wind erosion, for wind erosion in forest only being 1/10 of that on farmland and 1/35 of dust over farmland. Suggestions on how to prevent wind erosion have been put forward in this paper.
