摘要/Abstract

摘要： 河岸带木本植物是河岸缓冲带的重要组成部分，也是有效控制农业非点源污染进入水体的重要屏障之一。研究木本植物中的氮和磷含量既能帮助了解其所处生境的营养状况，又能为河岸带生态恢复提供指导。本文测定了浑河入库河道区常见的6种土著木本植物：垂柳（Salix babylonica）、白榆（Ulmus pumila）、蒿柳（Salix viminalis）、接骨木（Sambucus williamsii）、黄花忍冬（Lonicera chrysantha）和珍珠梅（Sorbaria sorbifolia）根、茎和叶中总氮和总磷含量。结果表明：6种木本植物总氮含量变化范围为9.02～36.48 mg·g^-1，总氮含量平均值为17.77 mg·g^-1；总磷含量的变化为3.06～8.19 mg·g^-1，总磷含量平均值为5.24 mg·g^-1。Pearson相关分析表明，植物各器官中氮、磷含量均呈现显著的正相关关系。接骨木根、茎、叶中氮含量高于其他物种，根、茎、叶中磷含量在接骨木和珍珠梅较高。

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.
