杉木人工林碳储量影响因素研究进展

A Review on Influencing Factors of Carbon Storage in Chinese Fir Plantations

杉木(Cunninghamia lanceolata)人工林是我国南方地区经营历史最长的人工用材林,其在木材生产功能和固碳、涵养水源等生态功能方面扮演着非常重要的角色,在应对全球气候变化进程中也发挥着不可替代的作用。然而,与天然林相比,人工用材林存在诸多问题,其中,如何在保证木材生产的同时提高生态功能,实现可持续发展,是目前杉木人工林经营管理面临的关键问题之一。碳储量是衡量森林生态功能的重要指标之一,森林碳汇有利于减缓温室效应,应对气候变化。本研究通过梳理和分析近年来与杉木人工林碳储量相关的文献,综述了林分年龄、经营管理措施、分布区域以及立地条件对杉木人工林生产力和碳储量的影响,在此基础上,提出了维持杉木人工林经济与生态效益相平衡的生产实践建议,也对杉木人工林碳储量研究的现存问题以及日后方向进行了探讨,以期为今后的相关研究提供参考。

As the longest history of artificial timber forest in Southern China,Chinese fir（Cunninghamia lanceolata）plantations play a very important role in the functions of timber production,carbon sequestration and water conservation,especially under the global change environment.However,compared with natural forest,there are many problems in artificial timber forest.Among them,how to improve the ecological function and achieve sustainable development while ensuring the production of wood is one of the key issues in the management of Chinese fir plantation.Carbon storage is one of the important indicators to measure the ecological function of forests.Forest carbon sinks are beneficial to mitigate greenhouse effect and cope with climate change.In this paper,the effects of stand age,management measures,distribution area and site conditions on the productivity and carbon storage of Chinese fir plantation were summarized and analyzed,from which the production practice guidance to balance the economic and ecological benefits of Chinese fir plantation was put forward,and the existing problems and future directions of carbon storage research of Chinese fir plantation were discussed to provide references for future research.
