| 摘 要： | 本文研究了陵川山区海拔900m处的荆条灌丛的群落结构及其生物量。灌丛的生物量是用回归模刑来预测的。其为:荆条W_(枝)=0.9213(D~2H)~(2.1932),W(叶)=0.2646(D~2H)~(0.6233),W(根)=2.0216(D~2H)~(1.6213);三裂绣线菊 W(枝)=0.3941(D~2H)~(0.9535),W(叶)=0.0243(D~2H)~1.0986W(根)=1.1859(D~2H)~(0.8848),其余灌木和草本植物用实测数据计算。最后得出,6月份荆条灌丛的总生物量为13.5859吨/公顷,其中灌木层12.2430吨/公顷,草木层1.3429吨/公顷。

| Abstract: | In this paper, the community structure of Vitex negudo var heterophylla (Franch) Rehd scrub and its biomass in the mountains area of Ling chuan Country, Shanxi Province, at an altitude of 900m is imestigated. The biomass of scrub is predicated by using re- gression medel, they are: V.negundo W(shoot )=0.9213(D~2H)~(2.1932),W(leaves)=0.2646 (D~2H)~0.6233, W(root)=2.0216(D~2H)1.6213. S. trilobata W(shoot)=0.3941(D~2H)~0.9535, W (leave)=0.0243(D~2H)1.0986,W(root)=1.1859(D~2H)~0.6848;in addition to this, the biomass of other shrubs and herbs is estimaled by utilizing practical measured data in fiel. Thus, the total biomass of serub is 13.5859t/ha, including the shrub layer 12.2430t/ha, the herb layer l. 3429t/ha in June. |
