近三年徐州市土壤墒情时空变化分析

Temporal and Spatial Variation of Soil Moisture in Xuzhou City in Last Three Years

利用徐州市2008～2010年10个站点的土壤墒情观测资料,对该区域土壤墒情的时空变化规律进行了分析,发现徐州市土壤含水量西部和南部相对较高,东部和北部较低,土壤墒情受降水量和土壤质地影响较大,降水偏少是造成2010年徐州土壤墒情较差的主要原因。

Based on the observed data of soil moisture in Xuzhou City from 2008 to 2010, this paper studied the temporal and spatial variation regularity of soil moisture in the area. It was found that soil moisture is high in the west and south of Xuzhou , and it is low in the east and north. The soil moisture was influenced remarkably by rainfall and soil texture. The main reason of low soil moisture in the year of 2010 is the low rainfall in Xuzhou City.
