【摘要】：【目的】為喀斯特區(qū)域的生態(tài)政策和生態(tài)補償提供重要的科技支撐�！痉椒ā坎捎每臻g代替時間的方法分析人工林和不同森林演替階段的土壤固碳能力�！窘Y果】與森林演替頂級階段相比,人工林土壤固碳潛力較大;與年齡相近的演替初期生態(tài)系統比較,人工林能夠快速地增加較深層(10~50 cm)土壤有機碳的含量;隨著森林年齡的增加,表層(0~10 cm)土壤有機碳呈增加趨勢,演替初級階段土壤中的有機碳占37.96%,演替中期的占32.73%,演替頂級的占31.02%;人工林0~10 cm土層有機碳占26.26%�！窘Y論】實施退耕還林進行人工造林能夠較快地增加土壤有機碳的含量,而且能夠增加較深土層的有機碳的含量。
[Abstract]:[objective] to provide important scientific and technological support for ecological policy and ecological compensation in Karst region. [methods] Spatial instead of time method was used to analyze the soil carbon sequestration ability of plantations and different forest succession stages. [results] Compared with the top stage of forest succession, Soil carbon sequestration potential of plantation is great. Compared with the early succession ecosystem with the same age, the plantation could rapidly increase the content of soil organic carbon in the deeper layer (10 脳 50 cm). With the increase of forest age, the soil organic carbon in the surface layer (0 鈮，
