The method of wind erosion ring and pitfall tripping were used to observe the effect of strip width on the wind erosion modulus and verify the results received by field mobile wind tunnel.The wind erosion and wind-blown quantity were determined and the results showed that wind-blown quantity was decreased when the width was narrower than 6 m and increased with the increasing of strip width when the width was 6~10 m,and decreased when the width was wider than 10 m in the stubble of naked oat.The wind-blown quantity decreased with the increasing of strip width in naked field when the width was less than 3.6 m,and increased when the width was wider than 3.6 m.The wind erosion quantity was decreased significantly in the stubble of naked oat when the width was less than 5 m,and increased when it was 5~10 m and decreased slowly when the width was wider than 10 m.The wind erosion quantity decreased with the increasing of strip width in adjacent naked field when the width was less than 3 m,and increased sharply when the width was 3~7 m and kept stable in 7~10 m then increased sharply again when the width was wider than 10 m.The wind erosion changed similarly in combination of keeping stubble and same width naked field as in the adjacent naked field,the wind erosion was increased with the distance to oats stubble increasing in the naked field of different width intercropping field.
