| 研究通过对滃江源国家湿地公园林地表层土壤进行采样，测试土壤酸碱度及养分指标，分析
土壤性质的空间分布格局，从而揭示湿地公园森林土壤养分及酸碱度的变化特征。结果表明：湿地公园
森林土壤整体呈现酸性，pH 平均值为 4.55，空间变异较小，且湿地公园的东部森林土壤酸性更强。土壤
全氮含量为 734.25~2136.25 mg/kg，整体较为丰富，但空间变异较大，表现为南高北低的趋势，与海拔梯
度分布基本一致。全磷含量在空间上总体较为一致，均值 338.93 mg/kg。土壤有机质含量总体较低，在研
究区范围内空间变异不明显。 |

| Abstract: |
| This study sampled forest surface soil in Hachuring Jiangyuan National Wetland Park, tested soil
pH and nutrient indexes, and analyzed spatial distribution pattern of soil properties, thus revealing the variation
characteristics of soil nutrients and pH in wetland park. The results showed that the soil in the wetland park was
acidic as a whole, with an average pH of 4.55, and the spatial variation was small, and the eastern part of the
wetland park was more acidic. Soil total nitrogen content ranged from 734.25 mg/kg to 2136.25 mg/kg, which
was abundant on the whole, but the spatial variation was great, showing a trend of high in the south and low in the
north, which was basically consistent with the elevation gradient distribution. The total phosphorus content was
generally consistent in space, with an average of 338.93 mg/kg. Soil organic carbon content was generally low,
and its spatial variation was not obvious in the study area. |
