河南省杉木林碳储量成熟问题研究

Study on Carbon Storage Maturity of Cunninghamia lanceolata Plantation in Henan Province

应用国际上森林碳汇项目中普遍采用的碳计算方法,对河南省南部不同立地条件下的杉木林碳储量成熟问题进行研究,分析不同立地条件对碳储量成熟的影响,结果表明:立地条件越好,成熟龄越早,达到成熟龄时的年平均碳储量也越高;碳储量成熟年龄的确定对选择树种和确定有关森林碳储量项目的期限具有重要意义。

The forest carbon storage maturity of Cunninghamia lanceolata plantations grown under different site conditions in southern part of Henan Province was studied by means of the carbon measurement methods commonly applied to the international projects of forest carbon sequestration,and the influences of different site conditions on the carbon storage maturity were also analyzed.The results showed that the better the site conditions were,the low-er the maturity age of carbon storage would be and the more the average carbon storage in maturity age would be. The determination of carbon storage maturity would be of great significance for tree species selection and for the de-termination of project duration of forest carbon sequestration.
