Carbon Stock and its Allocation Study on Theropencedrymion Ecosystem in Jiangle County
摘要
Abstract
The carbon stock and its allocation were analyzed among different age-groups of theropencedrymion ecosystem in Jiangle county by using the theory which was based on National Carbon Sequestration special investigation .Results showed that:the carbon stock of theropencedrymion ecosystem increased along with the growth of stand age ,the total carbon stock in young forest ,middle-aged forest ,mature forest ecosystem were respectively 121.13 t· hm-2 ,176 t· hm-2 ,253.33 t· hm-2;in young forest ,middle-aged forest and mature forest ,the tree layer carbon storage accounted for 33.16%,46.94%,28.27%;soil organic carbon stock accounted for 60.10%,50.45%,68.21%,meanwhile ,the carbon stock including soil layer and tree layer was more than 90%of the total car-bon storage of the ecosystem;soil organic carbon stock in each age-group of theropencedrymion reduced while soil depth increased , but increased with the stand age growth ,however,the carbon stock of 30~100 cm depth soil layer was slightly more than 10~30 cm depth soil layer in mature forest.In order to improve the accuracy of estimating carbon stock of theropencedrymion ecosystem , it should consider the differences of carbon stock in each age-group,layer,and organ of theropencedrymion ecosystem.关键词
