鄂尔多斯市区域自动站土壤相对湿度反演研究

摘要

The interrelated model was established with data of every ten days relative soil moisture, precipitation, mean temperature and former ten days relative soil moisture of Mar. -Oct. from 2006 to 2010 in Erdos. Based on terrain and soil type, 121 regional automatic stations were built. Use the relative soil moisture modeling, we inversed 121 regional automatic stations, relative soil moisture. The results effectively solved the problem of large region area but lack of monitoring station of soil relative moisture in Erdos, and provided new thoughts and methods for application of regional automatic station and drought monitoring.%通过鄂尔多斯市2006 ～ 2010年3～ 10月每旬土壤相对湿度数据与降水量、平均气温、上一旬土壤相对湿度数据建立相关模型,根据鄂尔多斯市的地形及土壤类型特点将该市建成的121个区域自动站气温、降水数据附值于土壤相对湿度模型,从而反演出区域自动站土壤相对湿度数据.研究结果有效解决了该市区域面积大而土壤墒情监测站点少缺乏代表性的问题,为区域自动站资料的应用、干旱监测等提供了新的思路和方法.
