摘要
研究了苏北沿海防护林主要树种刺槐(RobiniapseudoacaciaL.)和水杉(MteasequoiaglyptostroboidesHuetCheng)不同龄级林分对林下土壤盐分的影响及影响机制。结果表明,海防林能通过抑制土壤蒸发、促进土壤渗透及林分自身的物质循环等途径,减少土壤库中的盐分输入,增加土壤库中的盐分输出,从而有效地降低土壤含盐量。
The effect and effect mechanism of protective forest on soil desalting is studied.The results show that protective forest can remarkably control soil salt through three main paths:① reducing soil evaporation,②increasing soil permability,③accumulating salt in biomass.
