摘要

为探讨黄河三角洲盐碱地不同道路防护林对土壤的改良效应

选取白蜡(Fraxinus chinensis)+毛白杨(Populus tomentosa Carr)混交林、旱柳(Salix matsudana Koidz)林、柽柳(Tamarix chinensis Lour)林、白蜡(Fraxinus chinensis)林4种盐碱地道路防护林类型

并以裸地为对照

对其土壤容重和孔隙度、pH值和含盐量、土壤养分及C、N、S含量特征进行对比研究。结果表明:①与裸地相比

不同道路防护林具有降低土壤容重

增加土壤孔隙度的显著效应

并且表现出一定的压碱抑盐效应。随着林分类型的不同表现出一定的差异

其中混交林地土壤通气、透水性及压碱抑盐效果好于柽柳灌木纯林的

而旱柳林和白蜡林地的则较差。②不同道路防护林土壤有机质含量及速效性养分含量均有提高

其中土壤有机质含量依次为混交林>柽柳林>白蜡林>旱柳林

分别比裸地的增加49.5%

38.8%

18.9%

5.7%。③不同道路防护林下的C、N、S元素含量差别较大

元素含量表现为:C>S>N。N含量表现为混交林>柽柳林>白蜡林>旱柳林

分别是裸地的2.8
