Abstract: Woody plants play an important role in riparian zone, which can effectively prevent the agricultural non-point source pollution of river body. Studies on the N and P contents of woody plants can help the understanding of the nutritional status of the habitats which the woody plants are growing in, and provide guidance for the ecological restoration of riparian zone. This paper measured the total N (TN) and total P (TP) contents in different organs (root, stem, and leaf) of six woody plant species (Salix babylonica, Ulmus pumila, S. viminalis, Sambucus williamsii, Lonicera chrysantha, and Sorbaria sorbifolia) in a riparian zone in the upstream of the Hunhe River in September, 2011. The TN contents of the six woody plant species varied from 9.02-36.48  mg·g^-1, with an average of 17.77 mg·g^-1, and the TP contents varied from 3.06-8.19 mg·g^-1, with an average of 5.24 mg·g^-1. The Pearson correlation analysis showed that the TN and TP contents in the organs of the woody plants all showed significant positive correlations. S. williamsii and S. sorbifolia had relatively higher N and P contents in their root, stem, and leaf, as compared to the four others.
