本文根据1987年北京西山造林地区观测试验资料分析了阴阳坡微气候生态环境的特征;运用波纹比(?)能量平衡法研究坡地能量平衡各分量的变化规律;并对坡地上裸地和不同的水平条整地的水热状况进行了比较,整地能增加一定的热效益. In this paper, the characteristics of the micro-climatic ecological environment of the yin-yang slope were analyzed based on the observation data of the Xishan afforestation area in 1987 in Beijing. The variation law of the energy balance components of the slope land was studied by the energy balance method of wave ratio (?), The leveling of the water and heat conditions were compared, the preparation of land can increase the thermal efficiency.
