该项研究利用晴天条件下的实测资料，对间作小麦的毛白杨、山楂林的气象效应进行了研究。结果表明：（１）间作型人工林的动力效应非常明显，林内各测点的防风效能平均在４５％以上，最大达６２％。由于林木对气流的阻挡、摩擦及碰撞，林内的湍流交换明显比旷野麦田弱。（２）间作型人工林内的空气温度、土壤热通量等热力参数均比旷野的大。（３）林内的水文效应也较明显，相对湿度提高４％左右，０～２０ｃｍ上层的土壤湿度提高２％～３％，蒸发量也明显减少。
In this study, the meteorological effects of Populus tomentosa and hawthorn forests in wheat were studied by using the measured data in sunny days. The results showed that: (1) The dynamic effect of intercropping plantation was very obvious. The windbreaking effectiveness at all measuring points in the forest averaged over 45% and the maximum was 62%. Turbulent exchange within the forest is significantly weaker than that in the wilderness due to forest blockage, friction and collision with the airflow. (2) The air temperature and the soil heat flux in intercropping plantation are higher than those in the wilderness. (3) The hydrological effect in the forest is also obvious. The relative humidity is increased by about 4%. The soil moisture in the upper layer of 0 ~ 20cm is increased by 2% ~ 3% and the evaporation is obviously decreased.
