英文摘要	在调查2010年6—7月大风对黄河三角洲地区人工刺槐林的影响基础上;测定了风倒木形态指标、根系特征及其所处林窗的大小和土壤紧实度;分析滨海盐碱地人工刺槐林风倒的成因.结果表明:风倒是刺槐林遭受风害的主要形式;以胸径15～20cm的树木受害最严重.随着径级的增加;风倒木的树高、冠幅、冠高和尖削度显著增加;而枝下高、冠幅/冠高和枝下高/树高变化不显著;根系长度先迅速增加而后增加缓慢;根系质量逐渐增加.随林窗面积增加;倒木株数先增加后下降;100～150m2林窗倒木株数最多.土壤紧实度随土壤深度增加而增加;而随样木径级增加变化不显著.随径级增加;树形因子增大、根系生长受抑是刺槐风倒的重要原因;而林窗起到了促进作用.
中文摘要	Based on the investigation of the gale-caused damage to the Robinia pseudoacacia plantation in the Yellow River Delta in June-July 2010,this paper measured the morphological indexes and root system characteristics of fallen trees,gap sizes,and soil compactness,aimed to analyze the formation causes of the wind damage to the plantation.Wind-falling was the main form of the wind damage to the R.pseudoacacia plantation,and the damage was more serious for the trees with the diameter at breast height of 15-20 cm.For the fallen trees,their tree height and their crown width,height,and taper degree increased significantly with the increase of the diameter at breast height,while the height under branch,the ratio of crown width to height,and the ratio of the height under branch to tree height showed no significant change.With the increase of diameter class,root length had a rapid increase first but a slow increase then,while root mass increased gradually.With increasing forest gap area,the number of fallen trees decreased after an initial increase,being the maximum in the gap areas of 100-150 m2.Soil compactness increased with soil depth,but did not show significant changes with the stand diameter class.Increased tree shape factors and suppressed root growth resulting from the increased diameter could be the main factors causing wind-falling,and forest gap played a promotion role.
