| 摘 要： | 以样地调查资料为依据,分析了黄土高原不同坡向种群生物量投资、分配的空间动态规律及其与种群存活、生长和繁殖能力之间的关系.结果表明:坡向通过改变土壤含水率制约中国沙棘种群的行为特征,而种群通过生物量投资与分配调节形成与土壤含水率相适应的种群行为特征.①土壤含水率是决定种群行为特征的主导因子,土壤含水率按照北坡、西坡、峁顶...

| Abstract: | A survey was conducted to study the spatial dynamic characteristics of biomass investment and allocation of Hippophae rhamnoides ssp.sinensis populations under different slope aspects in the Loess Plateau based on the data of sample plots.And the relationships between biomass investment and allocation and population survival,growth and reproductive ability were analyzed.Results indicate that slope aspects restrict the behavioral characteristics of H.rhamnoides ssp.sinensis populations by changing soil moist... |
