| 摘 要： | 比较了多代杉木萌芽林强度间伐并补栽细柄阿丁枫(留杉栽阔)和保留杉木多代萌芽林(对照纯林)两种模式C贮量的差异,结果表明,留杉栽阔模式C库总量为163.25 t/hm2,比纯林模式C贮量(139.38 t/hm2)增加了17.13%.土壤层C贮量在整个生态系统C贮量中所占比例最大,留杉栽阔中的土壤C贮量比杉木纯林有了明显的增加(27.73%);另外,留杉栽阔后乔木层C贮量也有所提高,从杉木纯林的64.73 t/hm2增加到留杉栽阔后的68.99 t/hm2.因此可以看出,留杉栽阔经营模式可以增加杉木林生态系统的C吸存能力.

| Abstract: | Analyzed forest carbon reserves by compared management patterns of planting broad-leaved tree with reserving Chinese fir (PBWRC)with pure Chinese fir forest. The result showed that , total carbon stock of pattern of planting broad-leaved tree with reserving Chinese fir is 163.246 t/hm~2,which is 17.13% higher than that of pure Chinese fir pattern(139.377 t/hm~2).The carbon stock of soil is the largest part in the whole forest ecosystem that studied, also PBWRC is 23.73% higher than the control; in another aspect, the amount of organic carbon of tree layer had been improved after PBWRC was done, that is, from 64.726 t/hm~2 (pure forest)to 68.99 t/hm~2(PBWRC). Thus it can be seen, PBWRC can improve the carbon sequestration ability of Chinese fir ecosystem. |
