摘　　要： 对炼山与不炼山处理南酸枣人工林林下植被物种组成结构进行横向与纵向比较分析,结果表明,炼山处理下的南酸枣人工林群落各层的物种数目均低于不炼山处理群落,但在时间动态上2种处理下各层物种数目增加的幅度存在差异;炼山处理群落中灌木层、草本层及藤本植物平均个体密度低于不炼山处理的群落;炼山处理下群落物种科属组成数量都少于不炼山处理的群落,时间动态上前者增长的幅度比后者小。说明炼山处理不利于南酸枣人工林林下植被的生长发育。 The species composition of control burning Clwerospondias axiliaris plantation and non-burning plantation was analyzed. The results showed that the species number of C. axillaris plantation under the control burning was less than in the non-burning, but the increasing extent was different. The average individuals of various layer of C. axillaris plantation under the control burning were less than in the non-burning. The number of family and gena of the C. axiUaris plantation under the control burning was less than under the non-burning and the extent of increasing was less than in non-burning C. axillaris plantation. All this showed that control burning might be adverse to the growth of undergrowth vegetation of C. axillaris plantations.
