The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.

用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测，重点分析了23m、39m两层高度的观测结果，同时把观测期分为春季和冬季两个不同时间段作了对比：结果表明，不管冬季还是春季，39m高度所测的总通量值和夜间通量值都要小于23m的观测值，这种通量差别表明：23m高度的观测结果更接近当地生态系统与大气之间的通量交换值，在此种生态类型条件下用涡度相关法测碳通量时，在23m、39m两层高度之间仍然存在大气平流现象；该试验区植被在冬季仍然可以进行光合作用，而且光合作用所吸收的CO2大于呼吸作用所排放的CO2，因此该种生态系统在冬季仍表现为碳汇；春季的碳通量值为冬季的2倍以上。

The"carbon capture and sequestrate "technique conduces to decreasing that greenhouse gas emission and control world to be change into genial,Yet the deep straturm of the world sequestrate capacity of CO2 to the original commentary,Every state nation in world sequestrate CO2 and lifts oil field recovery ratio present situation and development tendency,Along with Chinese CO2 drives oil foregroun

The results show that SO2 gas itself does not influence the growth of ZY-1, however, when the SO2 concentration is higher than 50×10^(-6), ZY-1 growth rate and its CO2 fixation rate are all lowered and the pH of the medium is decreased, so measures must be taken to desulphurize or control pH of medium temporality. The presence of NO with concentrations of lower than 300×10^(-6)did not influence the growth of ZY-1 and its CO2 fixation, NO absorbed in the medium is utilized as a nitrogen source. The influence of dissolved soot dust on ZY-1 growth and its CO2 fixation could be ignored once the soot dust in the stack gases was disposed by the original method.

结果表明，烟气中的SO2是以增加培养液中的SO2^(-2)浓度及降低pH的形式来影响ZY-1的生长及其对CO2的固定的，当其浓度大于50×10^(-6)时，需要进行烟气脱硫或控制培养液pH变化来消除其影响；烟气中NO浓度不高于300×10^(-6)时，不影响ZY-1的生长及其对CO2的固定，反而可作为氮源供ZY-1生长用；对经过一般除尘处理的烟气来说，在利用小球藻ZY-1固定CO2时可不考虑溶解性烟尘的影响。

Linear CO desorbs earlier and quicker than twin and bridged CO with the progressive heating from 25 to 300°C at 0.1MPa, and the three types of adsorption disappear at 265℃.At 205℃ the adsorption amount of linear CO and bridged CO increases with the pressure from 0.1 to 3.0MPa, but the adsorption amount of bridged CO is more than that of linear CO. At 0.1MPa and 25℃, CO2can decompose into CO and then CO adsorbs quickly, namely, CO2→CO+O, but the wave numbers of the adsorptive CO from decomposed CO2 are different from the pure CO, which demonstrates the effect of on CO adsorption. With the pressure of CO2 from 0.1 to 3.0MPa at 25℃, the total adsorption amount increases and the band at 2052cm^(-1) shifts towards higher frequency.

压力保持0.1MPa，温度由25℃升至300℃时，线式比桥式先脱附，至265℃时，3种吸附基本脱附完全；当温度维持205℃不变而压力逐步由。0.1升至3.0MPa时，线式吸附增量较少，桥式吸附增量较多，CO2在0.1MPa，25℃时就能发生快速的解离吸附，即CO2→CO+O，其吸附行为表现为CO的线式吸附，但吸附峰与纯CO吸附时不同；当温度稳定在25℃而压力逐步升至2.5MPa时，不仅CO2吸附量增大，而且其2052cm^(-1)吸附峰有向高波数移动的趋势。

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.
