黄土区农草混合利用坡面土壤水分空间变异性（Spatial Variability of Soil Water Content on a Cropland-grassland Mixed Slope Land in the Loess Plateau, China）
土壤水分 农草混合结构 空间变异性
2010/12/29
通过对黄土区农草混合利用坡面的土壤水分分析，研究土地利用结构对土壤水分空间变异特性的影响。结果表明，研究区坡面土壤水分呈中等变异，且农草混合利用结构明显增加了土壤水分的空间变异强度，坡面土壤水分具有明显空间结构性。干湿条件下坡面0～60cm土层平均含水率的半方差最优理论模型分别为高斯模型和球状模型，且干旱条件较湿润条件下保持较高的基台值和变程，而块金值/基台值相对较低。Kriging插值结果显示...
