| 摘 要： | 在横山县朱家沟小流域采集111个样点,分析土壤属性与地形因子相互关系,进行空间预测分析.结果表明:土壤密度与复合地形指数CTI显著正相关,土壤有机质与复合地形指数CTI、汇流动力指数SPI、沉积物运移指数STI显著负相关,全磷只与坡度口显著负相关.多元线性逐步回归模型对于土壤密度和有机质拟合较好,而对于全磷,预测结果较差;回归一克里格预测有效地减小了残差,消除了平滑效应,预测极差更宽,对于局部的变异及地形、土地利用的关系体现更为细化,提高了预测精度. |

| Abstract: | Analysis and forecast on the spatial distribution and dynamics of soil properties is an important element of sustainable land management.Topography and land use are key factors which affect soil properties variability on catchment scale in the loess hilly area.Correlation analyses were carried out between soil properties(include bulk density(BD),soil organic matter(SOM) and total phosphorus(TP)) and terrain attributes.Finally,terrain attributes and land use types were used to predict spatial distribution of... |
