对祁连山不同类型条件下的祁连圆柏群落生物量和营养元素积累量的测定结果表明:祁连圆柏群落生物量为231.20t/hm2,其中乔木层占98.34%,灌木层占1.60%,草本层占0.06%;祁连圆群落年净生长量为4.41t/hm2,其中乔木层为3.96t/hm2,占89.80%,灌木层占7.25%,草本层占2.95%;群落营养元素积累量总计为3633.81kg/hm2,其中Ca、N、K所占比例较大,分别为54.27%、19.55%和11.05%,Zn所占比例最小,仅为0.03%。
The results showed that the biomass of Sabina przewalskii in Qilian Mountains was 231.20 t / hm2, in which the arbors accounted for 98.34% and the shrubs accounted for 1.60% , And the herb layer accounted for 0.06%. The annual net net growth of Qilian circular community was 4.41t / hm2, including 3.96t / hm2 for arbor layer, 89.80% for shrub layer, 7.25% for shrub layer and 2 for herb layer .95%. The accumulative amount of nutrient elements in the community totaled 3633.81kg / hm2, among which Ca, N and K accounted for a large proportion, accounting for 54.27%, 19.55% and 11.05% respectively. The proportion of Zn The smallest, only 0.03%.
