为探讨炼山后杉木各组分残余物性质特征，以杉木不同组分（枝、叶、皮、根）为试验材料，运用室内模拟方法，采用限氧升温炭化法，进行杉木各组分在不同的炭化温度下所得生物炭的特性比较研究。结果表明：随着炭化温度的升高，杉木各组分的生物炭的产率和水分逐渐降低，而灰分含量逐渐增加，其中在300～400℃温度范围内，杉木枝、根、皮、叶的生物炭的产率的降幅最大，分别达到33.22％、33.50％、32.85％、40.68％；杉木各组分生物炭的N、C含量皆随着炭化温度的升高而增加，而以杉木叶的生物炭（ LC） N、Mg含量最高，最大分别达到1.71％、33.48 g· kg-1；在同一炭化温度下，杉木枝的生物炭（ BC）的C含量明显高于其他组分生物炭，杉木皮的生物炭（ WC）的Fe、Ca含量高于杉木其他组分生物炭。

In order to explore the nature of the residue about Chinese Fir components after controlled burning ,put Chinese fir differ-ent components (Branch,Leaf,Bark,Root)as experimental materials,use the method of indoor simulation and heating carbonization method utilizing limited oxygen.To compare the characteristics of biochar at different carbonization temperatures of components for Chinese Fir.The Results showed that in the different processing of biochar ,with the increase of carbonization temperature ,all kinds of Chinese fir biochar production rate and moisture was gradually reduced , and the ash content increased , The carbon yield of fir branches,roots,bark and leaf components were declined largely at 300~400 ℃,Reached 33.22%,33.50%,32.85%and 40.68%respectively.With the increase of carbonization temperature ,all kinds of Chinese Fir biochar N ,C content increased ,and preparation by the Chinese fir leaves biochar ( LC) N content and Mg content were the highest ,reached 1.71% and 33.48 g· kg -1.In addi-tion,at the same carbonization temperature ,the C content of Chinese Fir branches biochar ( BC) was obviously higher than other bio-char,and the Fe and Ca contents of Chinese Fir bark biochar (WC) were obviously higher than other Chinese Fir biochar.
