安徽省乔木林固碳能力研究

以安徽省第六次森林资源连续清查结果为依据,对安徽省不同类型乔木林固碳能力进行了研究。结果表明,不同林种乔木固碳能力依次为：用材林（薪炭林（特种用途林（防护林;不同发育阶段乔木林固碳能力依次为：幼龄林（中龄林（近成熟林（成熟林（过成熟林;不同优势树种组乔木林固碳能力依次为：针叶林（阔叶林（针阔混交林;不同优势树种乔木林固碳能力依次是：杉木林（马尾松林（杨树林;同时,得出相同龄组但不同优势树种或相同优势树种但不同龄组的乔木林固碳能力也不同,其中杉木的幼龄林固碳能力最大,达到19.75 t/（hm^2.a）。

The Research on Carbon Fixation of Highwood in Anhui

A research on carbon fixation of different type highwood was performed according to the inventory results of sixth consecutive forests resource for Anhui. The results showed that the order of carbon fixation for different forest species of highwood was：timber forests 〉 fuelwood forests 〉 special use forests 〉 protective forests; the order of carbon fixation for different developmental stages of highwood was ：young forests 〉 middle age forests 〉 near mature forests 〉 mature forests 〉 over mature forests; the order of carbon fixation for different dominant tree speciesgroups of highwood was： coniferous forests 〉 broadleaved forests 〉 mixed coniferous and broadleaved forests; the order of carbon fixation for different dominant tree species of highwood was：pinus massoniana forests 〉 Chinese fir forests 〉 poplar forests; at the same time, also show that there are different carbon fixation in the same age group but a different species or the same dominant species but not the same age group, among them, the young growth of Chinese fir is the largest, reaching 19. 75 t/（hm^2 · a）.
