| Abstract: | Field soil water content measurement is a basic and important work, which plays a very important role in agriculture management. In this paper field soil water content was measured in a 20 hm~2 winter wheat field located in Linfen irrigation district of Shanxi Province, and the spatial variability structure of field soil water conter was analyzed using geostatistics as a tool and then the soil water spatial distribution map was imaged by ordinary Kriging technique, which can provide scientific guideline for the agriculture district soil water measurement and management. |
