渭河滩荒地与耕地土壤水分对比研究

Beach of the Weihe River under Two Land Use Soil Water Characteristics

通过对渭河渭南段周边农业用地以及荒地土壤的水分动态变化规律进行研究,结果表明:荒地与耕地的表层土壤水分在2011年10月到2012年4月间呈现总体下降趋势;深层土壤,不同土地利用形式下土壤水分季节变化存在明显差异,渭河滩荒地水分逐渐增加,变化幅度小;渭河滩耕地水分虽也在逐渐增加,但变化幅度较大.

This paper studies the various moisture dynamic laws of the agricultural land and the unused land soil in Weinan section of the Weihe River. The results show that the surface soil moisture in October to April, 2011, presents overall downtrend; as for deep soil, seasonal change of soil water under different vegetation has obvious differences, the Weihe beach waste water in- creased gradually and the range of variation is small; the Weihe beach farmland moisture is also gradually increase, but the change is more greatly.
