摘要:
对骆马湖东部滨岸带4种植物和土壤的总氮、总磷含量进行了测定，比较了植物组织氮磷分布变化，分析了土壤氮磷的空间分布及其与植物氮磷的关系。结果表明：滨岸带植物区土壤TN、TP显著高于无草区；4种植物群落立地土壤氮磷的水平变化差异较大，TN按近滨—前滨—后滨依次递减变化，而TP按后滨—近滨—前滨依次递减变化；从垂直变化来看，4种植物群落的立地土壤各层TN、TP差异显著，土壤表层（0—20 cm） TN最高；而TP最高值分别出现在黄蒿、茅草群落土壤表层以及芦苇、香蒲群落土壤次表层（20—40 cm）。4种植物的叶、茎、根等组织的TN、TP差异较大，但均以叶中含量最高，茎和根中含量较低，而且植物对氮素的吸收能力远大于磷素。相关分析表明，植物叶TN与土壤表层、次表层TN显著正相关，植物叶TP与土壤表层TP极显著正相关，植物茎TP与土壤次表层TP显著负相关。芦苇和茅草对土壤氮磷的吸收富集效应较好，而香蒲和黄蒿对土壤氮磷的吸收富集效应较弱。
Abstract:
The N and P contents in four plants and soils in riparian zone of Luomahu Lake were determined and analyzed, and relationship between plants and soils were discussed. The results showed that TN and TP in soils grown plants were significantly higher than control. Horizontal change pattern of N and P was different in soils of four plant areas, TN declined from nearshore, foreshore to backshore, while TP decreased from backshore, nearshore to foreshore. In vertical direction, the differences of TN and TP in each soil layer of four plants areas were significant, TN was the highest in surface soil (0—20 cm), TP was the highest in surface soil of I. cylindrica and A. scoparia areas or subsurface (20—40 cm) of P. australis and T. orientalis areas. The differences between TN and TP in leaves, stems and roots of four plants were significant, TN and TP were the highest in plant leaves, lower in plant stems and roots, and capacity of absorption to N was far more than P. The correlation analysis showed that TN of plant leaf was significantly positively correlated with TN in surface soil and subsurface, respective, TP of plant leaf was significantly positively correlated with TP in surface soil, and TP of plant stem was significantly negatively correlated with TP in subsurface soil. It was concluded that P. australis and I. cylindrica had a better uptake effect to soil N and P, but uptake effect to soil N and P of T. orientalis and A. scoparia was weaker.
