| 摘 要： | 甘肃小陇山林区是甘肃省最大的天然次生林区，它对维持大气中的CO2和O2的动态平衡,减少温室效应以及提供人类的生存基础有着不可替代的作用和地位。据此，根据植物光合作用的原理,林木生长与林木吸收并固定大气中CO2二者之间的因果关系，利用蓄积量转化法、区域生物量估算等方法来计算该林区吸收固定和保存大气CO2的生态服务价值。得出小陇山林区生物量现存量4.26×107 t,固定CO2 6.95×107 t,折合纯C量1.90×107 t，固C的价值为4.15×109元人民币。由于计算中存在许多不确定性，对计算结果的含义、生物量扩展因子以及木材比重的取值进行了讨论和说明。

| Abstract: | Xiaolongshan is the biggest natural secondary forest region in Gansu Province, it is unreplaceable in maintaining the dynamical equilibrium between CO2 and O2 in the air, in reducing the greenhouse effect as well as in providing human being survival foundation. According to the plant photosynthesis principle, relationship between forest growth and forest absorption of carbon dioxide from the atmosphere, by using the methods of quantity conversion and regional biomass estimation the ecology service values of carbon dioxide of the forests in this region were calculated, the results showed that in Xiaolongshan forest region, the biomass in this stock was 4.26×107 t, the fixed carbon dioxide was 6.95×107 t, equivalent to 1.9×107 t pure carbon, solid carbon value was 4.15×109 yuan. Because of the uncertainties in the calculation, the meaning of calculated results, the biomass expansion factor as well as specific weight of wood value were discussed and explained. |
