| 摘 要： | 粗木质残体(CWD)是森林生态系统重要的组成要素,由于定量研究某特定区域CWD的贮量和碳量的工作量相当大,需要长期的研究才能获得可信的数据,因此有关全球森林生态系统CWD的贮量和碳量仍不太清楚.本文根据国内外研究结果综述全球不同森林中CWD的贮量和碳库情况.结果表明:温带针叶林CWD贮量最高(30～200 t·hm-2),而阔叶林最低(8～50 t·hm-2);全球森林CWD碳贮量范围大致为75～114或157 Pg.各森林CWD贮量值变化大,因林龄、CWD分解阶段和人类经营活动(如疏伐、皆伐和控制火烧)而异.今后需更广泛地开展森林CWD调查,以更深刻理解CWD与林分结构、树种特性及干扰的关系.此外,为了更准确地评价CWD在森林生态系统中的生态价值,建议在更大尺度上对全球各类森林的CWD贮量和碳库进行长期的研究.

| Abstract: | Coarse woody debris(CWD) is an essential component of forests.However,quantification of both the storage and carbon stock of CWD in a given environment requires long-term studies conducted for collecting viable data,which is a fairly labor-intensive work.As a result,the storage and carbon stock of CWD in forest ecosystems are not clear.In this review,we attempt to compile all available estimates of CWD storage and carbon pool in a variety of forest ecosystems over the world.Global studies on CWD storage in ... |
