摘　　要：以干旱、半干旱区伊犁河流域察布查尔县境内新垦地丰产型小网格农防林为研究对象,对林网内农田和对照地的生态和经济效益进行了对比分析,结果表明:与对照地相比,农防林表现出强大的调节功能,林网内农田小气候得到明显改善,主要表现在各测点风速明显减小,空气温度降低、湿度增加,土壤温度日变化平缓等,只是距林缘不同距离的水平测点间,同一测点不同垂直高度间、一天中不同时段内各气象因子日变化规律差异均较大。另外,到目前为止,农防林对林内作物的增产效益也较明显,有防护林的油葵经济纯收益为对照地的1.25倍。New-reclamation land with small grid ＆ high-yield farmland shelterbelt in Chabuchar County in arid ＆ semiarid Yili river basin were chosen as research object. Eco-economic benefit of shelterbelt and the contrast land were analyzed comparatively. Result shows that： comparing with the contrast land, farmland shelterbelt shows powerful adjustment effect; inner microclimate of farmland shelterbelt, which is improved obviously, is mainly shown as sign/ficant reduce of wind speed, reduce of air temperature ＆ increase of humidity in each measuring point; the soil temperature has gentle diurnal variation;diurnal variation law of each meteorological factor has significant difference among the horizontal measure points within different distance to the forest edge, the different heights with the same points and at different time of one day. In addition, yield-increasing effect of farmland shelterbelt is also more significant, so far, the economic net income of oil sunflower inside farmland shelterbelt is 1.25 times than that of the contrast land.
