摘要
运用陇西黄土高原6个农业气象基本观测站土壤湿度资料(1982～2000年),分析了该地域土壤水分构成特征及0～200cm土壤水分运行、变化规律,拟合了100cm土层内土壤贮水及水分累积耗散曲线,分季节评述了区域内各地水分有效利用程度.
Based on the data of soil moisture in 6 basic agrometerological stations(1982-2000),the character of construction of soil water in LongXi Loessial Tableland has been analysed, the law of soil water moving and variation(0-200cm) has been found. The curves of water bearing and water consumption have been simulated, respectively. The quality degree of effective utilization of soil water has also been commented.
