摘　　要：对受污染后黄帝陵与药王山两地侧柏叶的一些生理指标的测定结果表明，水泥粉尘污染后侧柏叶的光合强度，呼吸强度和蒸腾强度均有不同程度的降低；气孔扩散阻力增大，方差分析显示，两地间污染程度差异极显著，药王山侧柏整体污染程度重于黄帝陵。现存污染条件下，黄帝陵侧柏不会死亡，但生长将受到影响。Some physiologic indexes in polluted needles of Platycladus orientalis at Huangdi Tomb and Yaowang Mountain were determined. The results showed that the intensities of the photosynthesis, respiration and transpiration of needles polluted by cement-dust, dropped to different extents, while the diffusing resistancde of stomata increased. The difference on polluted extent was extreme significance between Huangdi Tomb and Yaowang Mountain. Integral polluted level for Platycladus orientalis at Yaowang Mountain was more serious than at Huangdi Tomb. About existing condition, the Platycladus orientalis at Huangdi Tomb could not be killed, but their growth and scenery will be affected.
