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.
