高原沟壑区小流域不同收入水平农户土地经营行为差异研究

Difference of Land Management Behavior among Farm Households with Different Income in Watershed of Gully Region of Loess Plateau

通过对高原沟壑区长武王东沟小流域农户的实地调查,对不同收入水平农户土地经营行为的差异作了初步探索。结果表明:收入水平越高,园地比例越大,耕地比例越小;在单位面积园地上的投入量表现为高收入户>低收入户>中收入户,但收入水平越高的农户越注重技术投入;农户收入越高对土地的投入总量占纯收入的比例越小,但对园地的投入占总投入量的比例越高;在粮食作物种植中,高收入户更倾向于对口粮作物进行高投入,中收入户和低收入户对口粮作物和饲料粮作物投入差别不明显。
