摘    要:根据植被分布状况,在黄河三角洲国家级自然保护区核心区新生湿地内由黄河岸边至海滩方向布设两条平行样带,研究土壤营养元素空间分布特征.结果表明,黄河三角洲新生滨海湿地表层土壤中TN、NH4+-N、NO3--N、TOC、TS和TP平均含量分别为419.37mg·kg-1、3.27mg·kg-1、0.87mg·kg-1、3.43g·kg-1、381.27mg·kg-1和500.86mg·kg-1.从黄河岸边至近海光滩区,土壤中TN、NO3--N、TOC和TS含量逐渐升高.TOC、TN、NH4+-N和NO3--N含量在剖面上均表现为由表向下逐渐降低的规律.相关分析表明,土壤中TS、NO3--N、TN含量与TOC含量之间存在着极显著的正相关,土壤含盐量和pH是影响土壤中TOC、TS、NO3--N、TN含量和碳氮比大小的主要指标.

关 键 词:营养元素  空间分布  滨海湿地  黄河三角洲
