民勤沙区的起沙风速是≥５ｍ／ｓ；在当地农作物中，籽瓜对风害最为敏感，农作物的有害风速是１０≥ｍ／ｓ；一年当中，大风出现２个峰值，第１个峰值出现在４～７月份，这是流沙活动和风害的主要季节，第２个峰值出现在１１月份，这是流沙活动的又一个季节；在当地的灌木固沙林和机械沙障固沙措施中，胡麻杆沙障—梭梭林的价值系数最高，粘土沙障—梭梭林次之，单纯的麦草沙障的价值系数最小
Minqin sand area of the wind speed is more than 5m / s; in the local crops, the watermelon is the most sensitive to wind damage, crop harmful wind speed is 10 ≥ m / s; year, the strong winds have two peaks, the first The peak appeared from April to July, which was the main season for quicksand and wind damage. The second peak appeared in November, another season of quicksand activity. In the local shrub-sand fixation and mechanical sand barrier fixation, flax Pole sand barrier - the value coefficient of Haloxylon ammodendron the highest, clay sand barrier - Haloxylon forest followed by a simple wheat straw sand barrier value coefficient of the smallest
