surface soil of 31 stations were collected from Liaohe estuarine wetlands in May, 2009, divided into degraded areas and non-degraded areas based on vegetation growth, the content of biogenic elements and metrological characteristics of the samples were analyzed. The results showed that, the main reason for the difference of TOC up to five times is the different vegetation of the chek alkali canopy wetlands and reed wetland. Vegetation types have little effect on TP, the TP content is mainly affected by soil type and regional climatic conditions. Since the carbon and nitrogen are the structural elements of organisms, in vivo content is almost constant and has a homology, their sources are organic compounds. Therefore, there is significant positive correlation between the two.% 2009年5月在辽河口湿地采集了31个站位的表层土壤样品,根据植被生长情况分为退化区和非退化区。对土壤中的生源要素含量及计量学特征进行分析。结果表明：碱篷湿地与芦苇湿地植被的不同是导致 TOC 方面存在高达5倍差异的主要原因。植被类型对 TP 影响不大,TP 含量主要受土壤类型和区域气候条件的影响。由于碳、氮均是有机生物体的结构性元素,它们在生物体内含量基本恒定,且具有同源性,其来源均为有机物。因此,二者之间具有显著的正相关关系
