| 摘 要： | 对宜川黄土丘陵区的空矿地、油松林地和采伐地３类不同地表植被土壤水分在旱季和雨季的变化情况进行研究，结果表明雨季虽然降雨量大，但蒸散量也大，土壤水分入渗率低，和旱季相比除地表外雨季普遍偏低，空矿地表现得尤为明显。经过旱季土壤水分除地表土壤水分外二者之间差距明显缩小，旱季土壤分入渗率提高，油松林地表土壤水分旱季降低较少。 |

| Abstract: | The paper investigated soil moisture at three different surface vegeration induing open fields,felled fields and chinese pine forestry fields in dry and raing seasons,the results show that althoagh there are plenty of rocinfall in raing season,the amount of evaporation is more and less water seeping into soil,which is very obvions in open fields.There are only small differences in the dry season,and more water seeps into soil in dry season,but soil moisture of Chinese pine fields declined less in dry season. |
