摘    要:利用甘肃省黄土高原16个气象站1971~2000年气象资料、13个农业气象观测站及3个农业气象试验站土壤湿度资料,分析了近50年温度、降水及近30年土壤水分变化特征,用数理统计方法拟合了0~200 cm土壤贮水量动态变化,得出了土壤贮水量随气候变化的规律。研究表明,上世纪80年代以来,甘肃黄土高原土壤含水呈减少之势,0~200 cm土层土壤总贮水量春、秋季减少了40~90mm,夏季减少了20~36mm;土壤贮水适宜农作物生长的时段减少了2~3月,土壤水分匮缺的范围无论从时段及层次上都有所扩展。

关 键 词:气候变化  黄土高原  土壤贮水量  影响

Abstract:Based on the meteorological data in 16 meteorological stations and the data of soil water in 13 agrometeorological observing stations and 3 agrometeorological experiment stations,the variation of 50 years' temperature and precipitation and nearly 30 years' soil water content were analyzed.The variation of soil water content(0-200cm) was fitted with methods of statistics.The law of soil water content variation with climatic changing was obtained.The results showed that soil water content tended to ecrease from 1980s,and the amount of soil water decreased by 40-90mm in spring and autumn,20-36mm in summer,respectively.The length of the soil water holding period that was suitable for plant growing decreased by 2-3 months and the deficiency of soil water in both space and time was expanded during the period of plant growing.
Keywords:Climatic changing  Loessial Plateau  Soil water content  Impact
