基于农户地块水平毛竹Phyllostachys edulis林投入产出数据,比较分析了不同经营类型毛竹林经营效益及相应的固碳能力.结果表明:①在当前经营技术与市场环境下,如果考虑经营者自身劳动投入成本,材用毛竹林与笋竹两用毛竹林的经营效益没有明显差异,两者成林后年均净收益分别为5 500和5 800元·hm-2.②以60 a经营周期计算,材用毛竹林与笋竹两用毛竹林年均固碳量为6.51和5.26 t·hm-2· a-1,分别为同等立地适生条件下速生杉木Cunninghamia lanceolata林的1.87倍和1.51倍.今后需要加强毛竹伐后固碳效率研究,以便对毛竹综合固碳能力做出更为全面准确的评估;随着森林碳汇价值上升,经营材用林的比较效益会进一步提高,有利于提高竹林固碳.
Study on the cost-benefit and carbon sequestration capacities of Phyllostachys edulis plantations under different types of management
Based on the Phyllostachys edulis plantation input-output data collected from farmer households,this paper analyzed the cost-benefit of Phyllostachys edulis plantations and their carbon sequestration capacities under different types of management.The results had the following indications:(1) under the current market and technology conditions,if the labor cost being included,the annual net incomes of Phyllostachys edulis plantations under different types of management were quite close,which were 5 500 yuan per hectare for stem Phyllostachys edulis plantation and 5 800 yuan per hectare for stem and shoot Phyllostachys edulis plantation.(2)The annual carbon sequestration capacities were 6.51 and 5.26 ton per hectare for stem bamboo forest plantation,and timber and shoot bamboo plantation respectively,in a 60 year management duration,which were 1.87 times and 1.51 times of the fast-growing Chinese firs grown in the similar land sites and climate conditions.In the future,the study on bamboo product carbon storage need to be further improved,in order to evaluate Phyllostachys edulis carbon sequestration more accurately.With the gradually increasing value of carbon sequestration,stem bamboo plantation may become more profitable than stem and shoot bamboo plantation in the future,which will improve Phyllostachys edulis plantation's carbon sequestration capacity.
