摘　　要：本文开展了人工杨树林对盘锦盐碱地土壤水盐运动影响的研究。结果表明:盘锦盐碱地土壤养分匮乏且极度不均衡,杨树林和芦苇地的土壤条件优于裸地,表明乔木和草本植物可以改善土壤理化性质;盘锦地区5种人工杨树林能够在不同程度上增加土壤含水量、减少土壤盐分,其中,增加土壤含水量能力顺序为毛白杨>新疆杨>辽宁杨>小胡杨>银中杨,降低林地含盐量能力顺序为毛白杨>辽宁杨>新疆杨>小胡杨>银中杨。可见,土壤盐分与土壤水分之间总体成显著正相关关系,反映了“盐随水来、盐随水走”的水盐运动规律。This paper carried out the research on the influence of artificial poplar forest on the soil water and salt movement of saline-alkali land in Panjin.The results showed that the soil nutrients in the saline-alkali land in Panjin were lacking and extremely unbalanced,and the soil condition of poplar forest and reed land were better than that of bare land,indicating that arbors and herbs could improve the physical and chemical properties of the soil.Five kinds of artificial poplar forests in Panjin area could increase soil water content and reduce soil salinity to varying degrees.The order of the ability to increase soil water content was Populus tomentosa>Populus alba var.pyramidalis Bge.>Populus×Liaoningensis>Populus simonii×P.euphratica>Populus alba×P.berolinensis,the order of the ability to reduce the salt content of the forest stands was Populus tomentosa>Populus×Liaoningensis>Populus alba var.pyramidalis Bge.>Populus simonii×P.euphratica>Populus alba×P.berolinensis.It could be seen that there was a significant positive correlation between soil salinity and soil moisture,reflecting the law of water and salt movement of"salt comes with water,salt goes with the water".
