| 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。 |
| 关 键 词： | 陇西黄土高原 土壤水分 变化规律 有效利用程度 |

| Abstract: | 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. |
| Keywords: | LongXi Loessial Tablel Soil moisture Law of water-moving and variation Quality degree of effective utilization |
