土壤养分梯度,soil nutrient gradient
1)soil nutrient gradient土壤养分梯度
1.The niche breadths and overlaps of the 19 main wetland plant species under threesoil nutrient gradients in the Yellow River delta of China were analyzed by using the formulae described by Levins and Pianka,respectively.结果表明:各植物种在3个养分梯度上的生态位宽度值差异不大,优势种柽柳(Tamarix chinensis)、盐地碱蓬(Suaeda salsa)、芦苇(Phragmites australis)的生态位宽度值均较大;植物种之间的生态位重叠一般均较小,说明植物种在土壤养分梯度上产生了生态位分化。
