Larches of different ages have different net photosynthetic rate: the photosynthetic capacity of the young ones are bigger than that of the old ones; the stand density do not affect the net photosynthetic rate obviously; as far as the different stand classes are concerned, the diurnal changes of net photosynthetic rate is closely related to the photosynthetic active radiation. For the different layers of the crowns, there are greater ecological factors (illumination intensity, temperature, humidity etc.) on the upper layers than on the lower layers: the CO2 concentration of the lower layers is greater than that of the upper layers, which is indeed an exception; the net photosynthetic rate on the upper layers of the crown is generally greater than that of the lower layers. It showed that the CO2 concentration is not a main factor in the natural changing range of the CO2 concentration. Different directions of the crown have different photosynthetic active radiation, which is generally like exposed to the sun﹥North﹥in the shade of crown. However, the changes of net photosynthetic rate are not quite the same, which is North﹥exposed to the sun﹥in the shade of crown.

不同年龄的兴安落叶松净光合速率不同，年龄小的个体光合能力高于年龄大的个体；群团密度与净光合速率没有显著的相关关系；而对不同分级木，净光合速率日进程变化规律与光合有效辐射有着密切的联系；林内树冠不同层次各生态因子有上层大于下层的趋势，而CO2浓度在下层的含量高于上层，净光合速率上层普遍大于下层，说明在林内自然CO2浓度变幅内，CO2浓度不是主要因子；兴安落叶松树冠不同方向的光合有效辐射不同，一般向阳﹥北向﹥背阴，而净光合速率变化有北向﹥向阳﹥背阴的趋势。

During remediation experiment, the addition of benzene acid and Tween 80 gave higher CO2 evolution. The result of Microtox assay showed good correlation between aromatic rings of PAHs at low concentration.
