摘要:
在丹江鹦鹉沟小流域，利用土钻对坡耕玉米地不同深度的水分含量和养分含量进行了采样测定，应用传统统计学和地统计学的方法，对不同深度土壤属性进行了分析。结果表明：总氮和土壤有机碳的均值总体上表现为随土层深度的增加而降低；土壤水分含量则随土层深度的增加而增加；总磷随土层深度的变化不明显。总氮、土壤水分含量、土壤有机碳和总磷呈中等强度变异和强空间依赖性。在4个采样深度下，半方差模型对总氮、土壤水分含量和总磷在0—10 cm和10—20 cm的空间结构有很好的模拟精度；土壤有机碳的空间结构则较差，不能用半方差模型进行很好的模拟。经Kriging插值分析，总氮、土壤水分含量和总磷在0—10 cm和10—20 cm主要呈层状分布；从0—10 cm到10—20 cm，总氮平均含量由0.598 g/kg减小为0.310 g/kg，土壤水分含量和总磷的平均含量则分别从12.988%，0.229 g/kg增大到15.439%，0.366 g/kg。
Abstract:
The contents of soil water and soil nutrients on sloping corn land in Yingwugou watershed were determined for each soil sample of four different soil depths. Both traditional and geostatistics methods were applied to analyze soil properties in the four different soil depths.The results indicated that the mean contents of soil total nitrogen and soil organic carbon generally decreased with the increase of depth. The mean soil water content rose with the increase of depth. The soil total phosphorus did not indicate obvious change with the increase of soil depth. The total nitrogen, soil water content, soil organic carbon and total phosphorus had moderate variability and strong spatial dependence. The spatial structures of total nitrogen, soil water content and total phosphorus in 0—10 cm layer and 10—20 cm layer could be modeled with a high degree of confidence by semi-variograms in the four different soil depths. The soil organic carbon could not be modeled with a high degree of confidence for the poor spatial structure. The Kriging interpolation in 0—10 cm layer and 10—20 cm layer showed that total nitrogen, soil water content and total phosphorus were hierarchical distribution along the soil depth, the mean contents of total nitrogen decreased from 0.598 g/kg to 0.310 g/kg, and the mean contents of soil water and total phosphorus increased from 12.988%, 0.229 g/kg to 15.439%, 0.366 g/kg, respectively.
