降雨对烟地地表径流和土壤渗透性能的影响

Influence of rainfall to surface runoff and soil in flue-cured tobacco field

以烤烟种植地所设径流场为研究对象,采用相关分析、线性回归等分析方法,对不同降雨强度下产流时间及地表径流特性进行了分析,重点研究降雨因子对地表径流和土壤的影响。通过研究烤烟种植地降雨、地表径流和土壤入渗三者之间的关系。试验结果表明,地表径流与降雨呈线性关系,降雨量越大,线性关系越明显;而降雨对土壤的渗透性能也有明显影响。

Diameter flow field of smoke place was selected as research object in this paper. Adopting related analytical method, carried on the analysis in flow time under different rainfall intensity and the surface runoff characteristic, researched rainfall factor to surface runoff and runoff to silt influence. Through research the relations of rainfall, surface runoff and silt three in smoke place, discusses three in the rules, provides certain theory basis for the flue-cured tobacco saving water irrigation construction.
