摘　　要：本文以夏津县黄泛沙地130×260 m2小网格的农田防护林网为研究对象,对林网内不同区域处的风速、土壤湿度、土壤机械组成、土壤容重、土壤孔隙度、土壤风蚀深度及小麦产量进行了对比分析。分析结果表明:农田防护林具有明显的降低风速、增加土壤湿度、改善土壤机械组成、改良土壤物理性质、减少土壤风蚀量、增加小麦产量的效应,林网内3 H^5 H处的防风固沙和增产效应最好。The wind speed, soil humidity, soil mechanical composition, saturated hydraulic conductivity, soil porosity, soil wind erosion depth and wheat yield inside and outside the 130m 260m farm - shelter forest, which is located at Xia Jin city in the sandy area of the Yellow River, were studied. The results showed that the farm - shelter forest can improve the local conditions, soil humidity, soil mechanical composition, soil physic quality, wheat yield, and reduce the wind speed, wind -blown mass. As a result, the protective effect in 3H -5H is the best.
