Objective of this study was to understand the spatial pattern of soil properties and topographic factors and their relationships in a small watershed.We used classical statistical coupling with geo-statistical theory to characterize and compare the spatial variability of soil mineral N and topographic factors in the wind-water erosion crisscross region on the Loess Plateau.The results show that: ① The nitrate s variable extent is strong while other properties are moderate variability,and the impacts of soil...
