摘要
林下植被作为杉木人工林生态系统的重要组成部分,对林分稳定性、生产力及养分循环具有重要影响。文中通过剖析林下植被与杉木林分生产力、地下生态过程、生物多样性及碳储量等方面的内在关系,归纳总结林下植被对杉木人工林生长的作用规律,分析杉木人工林林下植被多样性的调控途径,提出在杉木人工林经营管理过程中合理保留林下植被多样性、进而提高林下生物多样性是提高杉木人工林生产力、减缓地力衰退的重要措施,旨在为杉木人工林长期可持续经营与管理提供科学依据。
As an important component of the Chinese fir plantation ecosystem,understorey vegetation has an important impact on the stability,productivity and nutrient cycling of the stand.This paper elaborates the internal relationship between understorey vegetation and the growth,underground ecological process,biodiversity and carbon storage of Chinese fir stand,summarizes the effect of understorey vegetation on the growth of Chinese fir plantation,and analyzes the regulatory pathways to understorey vegetation diversity of Chinese fir plantation.The important measures to improve the productivity of Chinese fir plantation and mitigate the decline of soil fertility include reasonable maintenance of the diversity of understorey vegetation in the process of management of Chinese fir plantation for improving understorey biodiversity,which would provide a scientific basis for long-term sustainable management of Chinese fir plantation.
