摘    要:为研究在同一气候背景下气象观测场与农田两地土壤湿度之间的互可代替使用关系,对2006—2008年在宿州市气象观测场和农田内开展的3年土壤湿度平行对比监测试验所获取的每旬一次两地土壤湿度监测数据,采用对比差值率、相关性分析等数理统计手段,研究分析了两地不同季节不同深度的土壤湿度之间的关系。结果表明:春、夏、秋、冬4季气象观测场地与农田的土壤湿度具有一致性,均为统计正相关。春季,取土日前有降水时,气象观测场地与农田的土壤湿度的差异高于取土日前无降水时的差异。夏季,气象观测场地与农田0~30 cm土层之间的

Abstract:Soil moisture measurement was conducted at the meteorological station and in farm land respectively from 2006 to 2008,for contrasting soil moisture mearements from the two cases under the same climate background.The relationship of soil moisture in the two cases is analyzed by the statistic method.The results show that there has marked consistency in the soil moisture from the two cases and there is significantly positive correlation in four seasons;in spring,the rate of difference in soil moisture between station and farmland measurements is larger in rainy weather than that without rainfall;in summer,the soil moisture measurements from 0 cm to 30 cm between station and farmland have a good relationship,and the difference rate is from-4.8% to 2.1% under the low vegetation condition;in fall,the difference rate becomes less and ranges from-4.3% to-1.4% under the low vegetation condition;in winter,the difference rate is larger,especially from 0 cm to 10 cm,greater than 17%.The mathematical model is established for the period with good correlation at various levels.
Keywords:Huaibei plain  meteorological station  farm land  soil moisture
