| 中文摘要: |
| ：通过对黄土高原23个农业气象观测站及3个农业气象试验站作物观测地段的土壤农业水分常数分析,以揭示该地域农业水分特性的分布特征。结果显示:在甘肃黄土高原,土壤容重从北到南、从浅层到深层呈减少趋势;凋萎湿度地域及垂直分布变化不大;田间持水量地域分布特征明显,陇西黄土高原大于陇东黄土高原;干旱的临界土壤含水量基本上为北部小于南部,最大值出现在陇西黄土高原的中部。 |

| Based on the data of soil moisture constant which was measured at test field of 23agrometeorological observatories and3agrometeorological experiment stations the distribution characters were analyzed． The results showed that soil density turned smaller from north to south and upper to deeper and the variation of wilting moisture did not appear big difference in the loess plateau of Gansu Province．It also indicated that the field water-holding capacity showed difference obviously in which Longxi’s was bigger than Longdong’s and the critical amount of soil water under drought of the north was smaller than that of the south the maximum value appeared in central section in Longxi loess plateau． |
