| 摘 要： | 以平朔露天煤矿排土场0.8 hm2刺槐+油松混交林复垦模式下固定监测样地为研究平台,以2010年和2015年两次调查数据为基础,分析了五年间样地内主要树种的短期死亡动态.结果表明:样地内所有树木总个体数由1026株减少到947株,死亡个体79株,占2010年总个体数的7.7%,刺槐和油松的平均胸径增量分别为1.44 cm和1.92 cm,样地内所有树木的胸高断面积增加2.3 m2·hm-2,中径级个体(7 cm

| Abstract: | Taking Pingshuo opencast coal mine dump 0.8 hm2 Robinia pseudoacacia mixed forest of Pinus tabulaeformis with reclamation models of fixed monitoring plots as the research platform.Based on the two survey data in 2010 and 2015, analyzing the short-term death dynamics of the main tree species during five years .The results showed that:The total number of trees re-duced from 1026 to 947.79 individual deaths accounted for 7.7% of the total number of individuals in 2010.The increments of the average DBH of Robinia pseudoacacia and Pinus tabulaeformis were 1.44 cm and 1.92 cm respectively.The increment of the basal area of the trees was 2.3 m2· hm-2.In the middle diameter class (7 cm
