以浙江省北部地区典型农村河岸带土壤为试验对象,采用野外调查结合室内分析方法,研究了安吉、桐乡、平湖试验区农村河岸带不同土地利用方式对土壤水文物理特性的影响。结果表明,河岸带不同土地利用方式对土壤体积质量的影响主要集中在0~20cm表层土壤,对40cm剖面以下土壤影响不显著(p〉0.05);河岸带不同土地利用方式对不同试验区土壤贮水量的影响趋势具有显著差异,其中3个试验区林地土壤饱和贮水量均较高。与农用旱地和林地相比,同一试验区水田利用方式下河岸带土壤入渗速率最低。
The effects of land use patterns on soil hydro-physical characteristics in rural riparian zone were analyzed from three experimental sites(Anji,Tongxiang and Pinghu)in north Zhejiang province using field investigation and laboratory analysis method.The results showed that soil bulk density in 0~20cm layer was significantly affected by land use patterns,however,effect on soil below 40 cm profile was not significant.The impacts of different land use patterns on soil water capacity were significantly different and soil water capacity in forest were all higher in the three experimental sites;Compared with those of dry land and forest,soil water infiltration rates were the lowest in paddy field.
