Turbulent fluxes were measured by an eddy covariance system at three levels over an intricate land surface on the southern part of the Loess Plateau, consisting of heterogeneous flat terrain and a lar...
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...
