| 研究通过云勇林场林地土壤采样，分析测试土壤性质及养分指标，运用地统计分析等方法，进而揭示林场土壤养分的空间格局特征。结果表明：林场土壤pH 值为3.04~4.96，整体呈现酸性，空间上东南区域的酸性更强。土壤全氮含量0.01%~0.17%，处于中等偏上水平，林场西部氮含量较低。全磷
含量为105~501 mg/kg，为中等到较高水平，在北部区域含量相对较低。土壤有机碳含量总体偏低，且在空间分布上与全氮含量基本一致。 |

| Abstract: |
| In this study, soil properties and nutrient indexes were analyzed and tested through soil sampling in Yunyong Forest Farm, and geostatistical analysis was used to reveal the spatial pattern characteristics of soil nutrients in forest farm. The results showed that the pH value of the forest soil ranged from 3.04 to 4.96, and the acidity was stronger in the southeast region. Soil total nitrogen content ranged from 0.01% to 0.17%, which was above the level of equality. The total phosphorus content ranged from 105 mg/kg to 501 mg/kg, which was moderate to high, and was relatively low in the northern region. Soil organic carbon content was generally low, and its spatial distribution was similar to that of total nitrogen content. |
