摘　　要：以夏津县黄泛沙地130 m×260 m的农田防护林网为研究对象,对林网内外的风速、空气温度、空气湿度、土壤温度、土壤湿度及水面蒸发进行了对比分析。分析结果表明:农田防护林具有改善小气候的功能,可以降低风速,增加空气湿度和土壤湿度,调节空气温度和土壤温度,减小水面蒸发,防风固沙,减少土壤风蚀量,林网内3 H^5 H处的防护效应最好。This text researched the 130m × 260m farmland-shelter forest in the sandy area of the Yellow River city of Xiajin as object, compared and analyzed the wind speed, air temperature, air humidity, soil temperature, soil moisture and evaporation inside and outside the forest. The results show： The farmland and shelter forest can improve the local conditions, reducing the wind speed, increasing humidity of air and soil, regulating temperature of air and soil, reducing evaporation of water surface, breaking wind and fixing shifting sand, reduce wind-erosion. As a result, the protective effect in 3 H-5 H is the best.
