Spatial Variation of Soil Water Storage (SWS) on Active Dune in Horqin Sandy Land
摘要
Abstract
A typical active dune in Horqin sandy land was selected as the study target and the spatial variation of soil water storage (SWS) at different depths was analyzed by semi-variograms analysis method on the base of full-scale sampling method. The research showed that SWS showed obvious spatial variation characteristics not only between different slops but also within the same slop, which could be attributed to the spatial variation of SWS of surface layer (0-40 cm) and shallow layer (40-100 cm), which were significantly higher than the deep layer (100-200 cm). The ranges of spatial heterogeneity of SWS of surface layer and shallow layers were lessee and were mainly resulted from stochastic factor, while SWS of deep layer was mainly affected by its physical structure, which had strong spatial dependence and higher variation range. It is practically significant to determine the pattern of SWS spatial variety of active dune in explaining the incursion and establishment pattern of pioneer plants for the establishment of manual sand stabilization.关键词
