查询词典 biomass

The analysis results for community species component and plant diversity showed that exclusion did change the species component and increase plant diversity remarkably, while the indicateor life-form structure, palatability analysis indicated that community for old exclusion is becoming perennity and unpalatability, whereas community for comparative exclusion is under stable non-equilibrium condition, in the view of vegetation coverage, mean height, biomass, palatability of plant composition, community for old exclusion has lower than new, comparative exclusion which proves partly that long-term exclusion can not increase grazing values for semi-arid rangeland.

对3种封育措施群落组成和生物多样性的分析结果表明，封育改变了群落的组成成分并增加了生物多样性，同时对群落植物的生活型、饲用价值分析计算结果则显示，老封育的群落植物逐渐向多年生发展，放牧价值开始降低，而对照区则明显处于一种非平衡的稳定状态。从3种措施植被的盖度、高度、生物量和饲用价值来看，老封育区均低于新封育区和对照区，表明长期封育不利于促进并提高草场的放牧利用价值。
