西吉县黄家二岔小流域地表径流和土壤渗透性能的研究
- Title:
- A Research For Soil Permeability and Surface Runoff in Huangjia-Ercha Small Watershed in Xiji County, Ningxia
- 摘要:
- 运用人工模拟降雨和径流小区试验方法，研究了宁夏西吉县黄家二岔小流域的土壤渗透性能。结果表明，影响土壤渗透性能的主要因子是土地利用方式、地面坡度、土壤含水率、土壤总孔隙度和雨强。据此，提出了充分利用干旱地区有限降水资源的建议。
- Abstract:
- The research for soil permeability and surface runoff in Huangjia-Er-cha small watershed in Xiji county, Ningxia, was done by means of artificial precipitation and runoff-plot testing method,which showed that primary factors affecting soil permeability are land utilization, slop, soil moisture, total porosity of soil and rain intensity.Then a suggestion was made to fully use the limited precipitation in arid area.
