综述了各种森林管理措施在全球CO2减排中的作用.这些管理措施主要包括减少森林砍伐速度,增加森林覆盖面积,加强对现存森林的肥料、火灾及病虫害管理,以薪材替代化石燃料等.同时探讨了中国的森林管理存在的优势和不足.目前中国森林生态系统主要是植被碳库,在全球碳循环过程中扮演着“碳汇”的角色,但其“碳汇”功能较小.因此,如何加强对新建人工林的抚育、病虫害和火灾管理,增强中国森林的“碳汇”功能,充分发挥其在CO2减排中的作用,是我们面临的重要工作
This paper summarized the roles of current forest management measures,e.g.,reducing deforestation rate,increasing afforestation and reforestation,strengthening the management of nutrient fertilization,fire hazard,and disease and pest injury,and substituting fossils fuels with charcoal,in global carbon dioxide migration,and analyzed the advantage and insufficiency of China’s forest management.The authors indicated that the current forest ecosystems in China,mainly their vegetation carbon pool,played a smaller role of carbon sink in global carbon cycle,and thus,it was important to strengthen the tending of newly cultivated plantation and the management of fire hazard and disease and pest injury,and to increase the carbon sequestration of our forests.
