摘　　要：为探讨辽河三角洲盐碱地杨树防护林对空气、土壤的改良效应,在盘锦选取4种杨树纯林,并以空白样地为对照,对其空气温湿度、土壤温湿度、土壤电导率和草本多样性进行对比研究。结果表明:毛白杨纯林改善林内空气温度、土壤含水率及土壤电导率的效果最明显;新疆杨纯林改善林内空气湿度和土壤温度及林内草本生物多样性的效果最明显。In order to investigate the effect of poplar shelterbelts on air and soil improvement in saline-alkalized of Liaohe River Delta,4poplar pure forest were selected in Panjin,compared with bare land,characteristics of air temperature and humidity,soil temperature and humidity,soil conductivity,and plant diversity were researched.The results showed that the effect of P.tomentosa improved air temperature,soil water content and soil conductivity were the most remarkable,and the effect of P.alba var.pyramidalis improved air humidity,soil temperature and plant diversity were the most significant.
