| 摘 要： | 应用地统计学的方法结合GIS空间分析技术,对在海伦市农田黑土区域以不同取样尺度采集的耕层(0~20cm)土壤样本进行了数据处理和分析,并对其土壤全量氮磷钾含量的空间分异特征、格局进行了研究和探讨。结果表明:两种尺度下土壤全氮和全磷均与土壤有机质呈极显著正相关。地统计学研究的方法表明两种尺度下全磷表现为高度空间相关,其变化主要受结构性因子的影响。其它土壤养分空间变异在不同的尺度下各有不同,揭示了影响其变化的生态学过程和功能不同。研究结果对科学地指导施肥、建立培肥制度和支持精准农业都具有重要的意义。图2,表2,参10。 |

| Abstract: | Geostatistics combined with GIS was applied to analyze the spatial variability of soil nutrients in topsoil(0-20cm) at Hailun county of Heilongjiang province in different scales.The results indicated that of total phosphorus(TP) was high dependent and other nutrients were different in 2 different scales.That means the spatial heterogeneity of TP was mainly impacted by structures and that of other soil nutrients were impacted by both structures and random factors.The correlation of soil organic matter content with TN and TP was highly significant in different scales.The analysis will be very useful for strategic distribution of farming production,guideline of fertility application and control soil erosion and degradation in black soil. |
