Also,the differences between those in sandy habitat and those in non-sandy habitat are significant.2 There existed two common factors called macroelement factor and trace element factor,which indicate the contents of macroelements and trace elements in the plants respectively.

豆科与禾本科相比，豆科植物因其具固氮能力，所含大量元素水平较高，而禾本科植物因细胞壁硅质化，含微量元素稍高；沙质生境因其养分贫瘠，植物的大量与微量元素均较非沙质生境中的低；特别是本区地带性土壤-栗钙土与特异性生境沙带中的疏林沙土相比，疏林沙土上植物大量与微量元素含量较栗钙土区植物明显偏低。
