摘要：
Spatial coherency analysis is suggested as a method for examining the temporal persistence of a spatial persistence of soil water storage (0-1. 7 m) measured every 10 m in a 720-m-long transect for drying and recharge events. Soil water recharge altered the spatial pattern of water storage at small scales which was significantly related to surface (topographic) curvature. Drying did not alter the spatial pattern of soil water storage. The study supports the concept that soil water storage at a point is the product of hydrologic processes operating at different spatial scales.
