Study on the cost-benefit and carbon sequestration capacities of Phyllostachys edulis plantations under different types of managements

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.
