本研究考虑了排水高山湿地土壤有机碳、氮、磷储量的空间变异性及其与土壤性质的可能关系。在青藏高原东南部典型的高寒湿地，采用网格取样法采集了表层0 ~ 0.30 m土壤样品。排水型高寒湿地土壤有机碳密度（SOCD）、全氮密度（STND）和全磷密度（STPD）具有较高的空间变异性。球形模型最好地描述了SOCD和STPD的半变异函数结构，指数模型最好地描述了STND的半变异函数结构，范围参数为
This study considers the spatial variability of soil organic carbon, nitrogen, and phosphorus storage in a drained alpine wetland and the possible relationships with soil properties. Top 0-0.30 m soil samples were collected in a typical alpine wetland in the south-eastern Qinghai-Tibet plateau using grid sampling. There was high spatial variability for soil organic carbon density (SOCD), soil total nitrogen density (STND), and soil total phosphorous density (STPD) in the drained alpine wetland. Spherical models best described the structure of the semivariograms for SOCD and STPD, and an exponential model for STND, with the range parameter of
