摘　　要：科尔沁沙地不同造林密度对杨树生长状况及总产量的影响对比分析结果表明,科尔沁沙地杨树高密度造林生长早期开始受到抑制,生长缓慢,形成了低产低效林和枯死现象,降低了蓄积量。但一定密度和林龄范围内,高密度造林也同样取得更高的生物量产量。Afforestation with different planting density for growth conditions of poplar were analyzed by Horqin sand land . The results showed that afforestation with high density was inhibited in the early period, grows slowly even appears death , formed low yield or efficiency poplar forest , reduces the stock volume.But it can gain higher biomass in some forest age and density .Therefore this text will provide the basis for thinning and appropriate density in the process of cultivating poplar .

关 键 词：低密度造林 高密度造林 效果分析
