对南洞庭湖区3类不同类型湿地土壤有机质及全氮的空间分布特征进行了研究. 结果表明:3类湿地土壤养分差异较大,湿地表层土壤有机质和全氮含量从高到低依次为湖草滩地、芦苇滩地、泥沙滩地;土壤全氮与有机质呈极显著正相关关系(P

The spatial distribution characteristics of soil organic matter and nitrogen in 3 types wetlands of South Dongting Lake Floodplain were studied in this paper. The results showed that there were both significant differences, of soil organic matter and nitrogen in 3 type wetlands, the horizontal distribution of soil organic matter and nitrogen was Carexspp-dominated floodplain Phragmites-dominated floodplain mud and sand-dominated floodplain. There were significant positive relationship（P 0.01）between soil organic matter and nitrogen, the regre...
