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。
Taking the high-yielding small-scale farmland-controlled forest of newly cultivated land in Chabuchar County as the research object in the arid and semi-arid region, the ecological and economic benefits of the farmland and the controlled land in the forest network were compared and analyzed. The results showed that Compared with the control, the anti-forest stands have a strong regulatory function. The microclimate of farmland in the forest network has been significantly improved, mainly showing that the wind speed at each measuring point is obviously reduced, the air temperature is decreased, the humidity is increased, and the diurnal variation of soil temperature is gentle , Only the distance from the forest edge of the horizontal measuring points, the same measuring point at different vertical heights, daytime different periods of the meteorological factors in the daily variation are larger. In addition, up till now, the yield increase of agricultural crops for afforestation has also been more obvious. The net economic income of oil sunflowers with shelterbelts is 1.25 times of the control.
