摘  要:
运用森林生态学典型样地法设立标准地并获取野外数据,采用重铬酸钾—硫酸氧化湿烧法测定了生物、土壤中的碳。通过对兴安落叶松林3个类型生物及土壤碳储量的比较研究表明:兴安落叶松不同器官中碳素密度变化范围为0.4946~0.5352g/g;杜香落叶松林、草类落叶松林、杜鹃落叶松林生态系统总的碳储量分别为173.21t/hm2、207.81t/hm2、118.95t/hm2,其中生物碳储量分别为53.41t/hm2、86.23t/hm2、33.76t/hm2,土壤碳储量分别为119.80t/hm2、121.58t/hm2、85.19t/hm2;兴安落叶松林有机碳年净固定量为3.51t/(hm2.a)。

摘  要:
The experiment was conducted to determine the carbon Storage of vegetation and soil using the typical sample plot method of forest ecology to obtain field data by means of the Walkley-Black acid digestion method. The carbon storage of vegetation and soil in Larix gmelinii forest in three forest types showed that the carbon density in different organs of the main tree species in Larix gmelini forests ranged from 0.494?6g/g to 0.535?2g/g.The total carbon storage of the ledum palustre larix gnelinii forest, herbage larix gnelinii forest and rhododendron larix gnelinii forest is 173.21t/hm2,207.81t/hm2,118.95t/hm2,in which the amount of carbon fixed by vegetation is 53.41t/hm2、86.23t/hm2、33.76t/hm2,and fixed by soil is 119.80t/hm2,121.58t/hm2 and 85.19t/hm2. The annual net carbon storage by broadleaved Korean pine forest is 3.61 t/(hm2a).
