以长白山高山冻原为研究对象,对土壤碳和氮、磷、硫养分在不同海拔和不同植被类型间的变化进行研究。经试验分析和数据处理,得出以下结论:海拔和所测试的土壤理化因子都高度相关;不同植被类型下土壤理化因子差异显著(除全硫)(p<0.05);全碳和全氮在土壤表层(0~10 cm)的含量大于10~20 cm的土层,而全磷和全硫含量在10~20 cm土层明显大于土壤表层0~10 cm;长白山高山冻原(15195 hm2)土壤中(0~20 cm)全碳、全氮、全磷和全硫储存分别为3134613 t、57060.82 t、14413.35 t和23099.64 t;土壤表层(0~10 cm)储量所占的比例分别是59.3%、57.9%、47.4%和49.1%。
Taking Changbai Mountain alpine tundra as the research object, the changes of soil carbon, nitrogen, phosphorus and sulfur in different altitudes and different vegetation types were studied. Through the experimental analysis and data processing, the following conclusions are drawn: Elevation and soil physical and chemical factors tested are highly correlated; soil physical and chemical factors under different types of vegetation are significantly different (except total sulfur) (p <0.05); total carbon and total nitrogen The content of soil surface layer (0 ~ 10 cm) was larger than that of soil layer of 10 ~ 20 cm, while the content of total phosphorus and total sulfur was 0 ~ 10 cm in the soil layer of 10 ~ 20 cm in the 10-20 cm soil layer. The alpine tundra of Changbai Mountain (15195 hm2) The total carbon, total nitrogen, total phosphorus and total sulfur stored in the soil (0-20 cm) were 3134613 t, 57060.82 t, 14413.35 t and 23099.64 t, respectively. The proportions of soil surface layer (0-10 cm) were 59.3 %, 57.9%, 47.4% and 49.1%.
