| 摘 要： | 在中科院禹城综合试验站102 m×52 m面积内选择样点,采用经典统计学和地质统计学方法,对土壤稳渗率和入渗经验指数的空间变异性进行研究.结果表明,土壤稳渗率和入渗经验指数均服从对数正态分布,表现出空间变异结构,但不是完全的随机变异,在一定范围内存在着空间相关现象.利用克立格最优内插估值法,绘制了土壤稳渗率和入渗经验指数的等值线图,可准确、直观地了解该地区农田土壤垂向透水性的空间分布规律. |
| 关 键 词： | 入渗特性 空间变异性 稳渗率 入渗经验指数 |

| Abstract: | Spatial variability of the steady water infiltration rate and infiltration experiential index is studied with traditional statistics and Geo-statistics.The results show that both steady water infiltration rate and infiltration experiential index obey lognormal distribution.The soil property is imbued with spatial variation-structure,but it's not perfect for random variation,and there exists spatial correlation phenomenon in a limited range.The authors also use the Kriging interpolation technique to estimate... |
