摘  要:
详细论述了粗死木质残体(CWD)的内涵及其分类系统,对国内外粗死木质残体的研究动态进行了梳理与归纳,并指出CWD的生态功能已引起国内外研究者的广泛重视,特别是对CWD的贮量、分解量(率)、养分贮量(C、N等)、动态变化过程及其特征、CWD对森林生态系统的更新演替和生物多样性的保护功能、强大的水土保持功能(抑制水土流失、改善土壤质地)以及与水土保持相关的幼苗保育功能等方面都作了较多的论述和研究。

摘  要:
Coarse woody debris(CWD) is an important structural and functional component of forest ecosystems and plays a key role in keeping the integrity of ecosystems.The concept of CWD and its classification system were specified,and the dynamics of the domestic and abroad study on CWD were sorted out and summarized.Besides,it was pointed out that the ecological functions of CWD had been attached great importance to by the researchers at home and abroad,especially those facets like the CWD storage,decomposition rate,nutrients storage(C and N,etc.),the process of dynamic change and its characteristics,the influence on the regeneration and succession of forest ecosystems and biodiversity protection,strong water and soil conservation functions of CWD(inhibiting water and soil loss,improving soil texture),and the function of seedling nursing relative to water and soil conservation,were presented and studied.
