摘　　要：为弄清郑州黄河滩地不同植被土壤养分的含量与分布特征,采用类型抽样方法选取样本、扩散吸收等方法测定土壤养分含量,对其进行了分析与研究。结果表明:在95%置信度下,6种植被土壤有机质、碱解N和全盐含量存在显著差异,有机质和碱解N含量显著相关,但与全盐含量相关性不明显。天然灌木丛土壤有机质和碱解N含量最高,分别达到17.08g/kg和76.51mg/kg;人工防护林土壤的有机质和碱解N含量分别为10.03g/kg和43.25mg/kg,长期开垦农田和新开垦农田土壤的有机质和碱解N含量低于其他植被(光板地除外),二者没有显著差异。光板地土壤全盐含量达8.60g/kg,远高于其他5种植被土壤的全盐含量(均值为1.72g/kg)。To explore the nutrient contents and distribution characteristics of soil with different plant communities in the yellow river beach land of Zhengzhou,sampling method was used to choose samples and diffusion absorption method was used for determining soil nutrient content.The results showed that there were significant differences of soil organic matter （OM）,alkaly-hydrdytic nitrogen,and total salt content among six kinds of typical plant communities（P〈0.05）.There was a close positive correlation between the content of OM and alkaly-hydrdytic nitrogen,but no significant correlation with total salt content.The contents of soil OM and alkaly-hydrdytic nitrogen in bush-land were the highest of all,17.08 g/kg and 76.51 mg/kg respectively,which were 10.03 g/kg and 43.25 mg/kgin woodland.And there was no significant differences between long-term cultivated farmland and newly reclaimed farmland（P〈0.05）,though that was lower than other cases except bare-land.The total salt content was 8.60 g/kg in bareland,much higher than the other five typical cases （1.72 g/kg in mean value）.
