【摘要】 应用MILOS520自动气象站观测了海伦地区三叶草地全年土壤温度,为说明地温和气温年际间变化规律,对比气温获得黑土区年际间存在的两个土温和气温大致相等的转折期,将全年分成三个类型区,分别比较这几个时期土温气温的变化特征。得出黑土区土温气温年际间变化的四个特征时期:土温气温升高重合区(3月);土壤温度上升区(4、5、6、7、8月份);土温气温降低重合区(9月);土壤温度降低区(10月到来年2月份)。更多还原

【Abstract】 According to the whole year’s observing data of soil temperature in clover field and air temperature by MILOS520,discovered two equal periods between soil and air annual temperature.Then,divided whole year into three style zones and compared the characteristics.Pointed out four periods:rising coincident region with soil and air temperature(March);soil temperature rising zone(April to August);reducing coincident region with soil and air temperature(September);soil temperature reducing zone(December to next February).更多还原
