Abstract:Based on the study on the water balance and principle of wind prevention of sand-fixingPopulus forest belt with low vegetation coverage ( 15% -25%), the vegetation communities were investigated. In order to reveal the effects of sand-fixing forest belt on the natural vegetation restoration, the recovery process and species diversity difference of vegetation were studied under different interband istances and varied recovery years of sand-fixing forest belts in Aohan, Chifeng City, Inner Mongolia.The results show that : 1 ) the vegetation recovering effects depends on the distance of Populus forest belts. The rational distance will significantly improve vegetation recovery effect ; 2) after the same recovering period, the vegetation with the interband distance of 20 m has better recovery effects than those of 15 m and 10 m, and has more stable community ; 3) with interband distance 20 m of sand-fixing forest,the vegetation could grow to natural community after many years, whereas, vegetation will develop to sparse with interband distance 10 m.
