| 摘 要： | 采用地统计学的理论和方法,研究退化红壤区的土壤4种物理性质的空间异质性。变异函数分析结果表明:退化红壤的物理性质有中等程度的空间相关性,土壤容重与毛管孔隙度具有明显的空间异质性,在0～20cm土层深,有效变程尺度分别为700m和12650m,自相关部分的空间异质性为68.5%和73.6%,明显大于随机部分的空间异质性;在空间自相关范围内,土壤各物理因子的空间异质性有重要的密切关系。 |

| Abstract: | Based on the principle and methods of geostatistics,the spatial heterogeneity of soil physical properties under the degenerated red soil of Jiangxi is studied.The results of semivariogram analysis show that there is the spatial pertinence of middle degrees in soil physical factors and the distinct spatial heterogeneity between the bulk density and capillary porosity;The effective scale of spatial heterogeneity is 700m and 12650m in 0~20cm deep of the soil,respectively;the nugget variance to sill ratio reveal that spatial heterogeneity of autocorrelation in total spatial heterogeneity is 68.5% and 73.6%,respectively,which greatly exceeds that of the random part.The semivariograms of these physical factors have close relationships with each others. |
