摘　　要：通过对集二铁路沿线风沙害严重路段所布设的各种风沙害工程控制措施的野外观测试验,从控制措施对近地表风速的影响、不同措施的阻积沙效益以及保水效果等方面对各种风沙害控制措施的效益和适用性进行了分析和讨论。研究表明:几种措施的减速效果依次为砖墙>轨枕>荆笆>树枝;直立型控制措施障后防护距离约为其高度的5～10倍,控制措施保水能力大小依次为粘土>原始>荆笆>轨枕>树枝>草方格。The protecting benefits and applicability of the control measures set up along the wind and sand harm section of Jier railway are studied by the field observation experiments, including the effects on wind speed of earths surface and the sandprevent and waterkeep effects, and so on. It shows that:① the control measures wind speeddown effects:brick wall > crosstie > basketry > branch; ② the effect area behind the stand measure is about five to ten times of the measures height; ③ the control measures waterkeep benefits:clay cover > original > basketry > crosstie > branch > grass pane. 
