小浪底库区河岸带植物物种多样性与土壤因子的关系OA
以黄河中游末端地段小浪底库区河岸带为研究对象,采用典型对应分析法(CCA),对物种分布和多样性与土壤因子的关系进行研究.结果表明,小浪底库区河岸带共发现植物 31 种,17 科 28 属,其中禾本科、菊科、蓼科和锦葵科植物最多,苍耳和狗牙根为优势种.随着河流流向小浪底库区南北两岸的有效磷和有机质呈下降趋势;速效钾、含水量和全氮无显著变化.从变异系数看,土壤含水量、有机质、速效钾、全氮及有效磷均属于中等变异程度(0.1≤C≤1),表明土壤养分分布总…查看全部>>
The study focused on the riparian zone of the Xiaolangdi Reservoir area located at the terminal section of the middle reaches of the Yellow River.The Canonical Correspondence Analysis(CCA)was employed to investigate the relationship between species distribution and diversity with soil factors.The results indicated the following:A total of 31 plant species were found in the riparian zone of the Xiaolangdi Reservoir area,belonging to 28 genera across 17 famili…查看全部>>
