中文摘要：

对杭州市高架下、公路边和文教区3个功能区内的土壤有机碳、氮、磷及生长于3个功能区上的广布植物节节草植株有机碳、氮和磷的分布特征进行了分析,并讨论了3个功能区中土壤与节节草之间的相关关系.结果表明,不同功能区内土壤有机碳的平均含量不同,土壤全氮含量存在极显著差异,而土壤全磷的平均含量差异不显著;不同功能区节节草植株有机碳平均含量依次为校园内〉高架下〉公路边;植株体内有机碳含量与相对稳定的土壤有机碳有关,而其植株内的全氮含量表现出与相对不稳定土壤相关的趋势.

英文摘要：

Abstract： The paper analyzed the distribution characteristics of the organic carbon, nitrogen and phosphorus in the soil from 3 different functional districts in Hangzhou as well as the organic carbon, nitrogen and phosphorus of Hippochaete ramosissimum, which distributes commonly in these different functional districts, and studied the relationships between them. The results show the average content of organic carbon in different functional districts is different, and there are significant differences of nitrogen content while the differences of phosphorus content are indistinct. The organic carbon of Hippochaete ramosissimum in different districts can be ranked in a decreasing order as campus〉viaduct bridge〉roadside. The organic carbon content in the plants is related to the stable organic carbon content in the soil, and the nitrogen content in the plants is related to the unstable soil.
