| 摘 要： | 以陕西省吴旗县柴沟流域为例研究了退耕还林(草)区不同土地利用类型的土壤水分-物理性质,结果表明:实施退耕还林(草)工程后,土壤水分-物理性质得到了明显改善,土壤自然含水率提高了48.0%,持水量是农田的1.55倍,孔隙度是农田的1.12倍,在不同程度上改善了土壤物理性质,提高了土壤保水、蓄水性能,改善了土壤结构。

| Abstract: | The paper studies the soil moisture-physical properties of different categories of land utilization of the region of returning land for farming to forestry(grass) by taking Chaigou Watershed of Wuqi County,Shaanxi Province as an example.The results show that with the project of returning land for farming to forestry(grass),the soil moisture-physical properties has been remarkably improved and the natural soil moisture increased by 48%.The moisture holding capacity is 1.55 times of that of the farmland and the total porosity 1.12 times of that of the farmland,improving the soil physical properties,increasing the capability of water retention and accumulation of the soil and improving the soil structure to a certain degree. |
