, 2008 塔里木河下游植物繁殖体形态对土壤种子库垂直分布的影响研究结果表明,1)中度大小的种子在土壤种子库中的数量和出现的频次占很大优势。与小种子相比,土壤种子库中繁殖体重量较大的种子在表层土壤中的数量和出现的相对频次最丰富;2)繁殖体方差与种子数量和出现频次间呈"驼峰"型关系。近似圆形的种子在表层土壤中占的比例较高,在深层土壤中的比例较低,而扁平、细长的种子则表现为相反的趋势。繁殖体形状对土壤种子库中种子在各土层中出现相对频次影响不大;3)土壤种子库中种子数量和出现频次与单位体积的繁殖体重量(M/V ...

, 2008 以塔里木河下游为研究区,选择退化程度不同的4个典型断面19个样地,利用种子萌发法进行了两年的种子库土壤萌发实验,试图就生态严重退化区的土壤种子库与地上植被的关系以及退化程度的差异对种子库特征的影响开展针对性的研究。结果显示:①塔里木河下游土壤种子库的基本特征是:种子库密度小、物种种类组成较单一、物种的多样性低和地上植被与种子库的相似性较低;②随退化程度的加剧,土壤种子库密度明显下降、表层种子库比例升高、一年生草本占优势逐渐向多年生草本和灌木转变、地上植被与土壤种子库物种组成上差异显著 ...

, 2008 对半干旱区黄土高原草地在封育和放牧条件下土壤种子库种子密度、种子库组成、种子库物种多样性及均匀性进行了比较研究,并得出主要结论:1)封育提高土壤种子库的植物种类和密度,使优良禾草和多年生植物增加。2)种子库的垂直分布规律是随着土层的加深,种子在数量上递减的速度较快。3)坡向和坡位对土壤种子库有较大影响,种子库密度变化趋势是阴坡>阳坡;坡下部>坡中部>坡上部。4)从丰富度、Shannon-Wiener多样性和均匀性3个方面比较分析封育和放牧样地土壤种子库多样性 ...
