气候变化极大地改变了三种落叶松的适宜分布区。

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

通过扫描电镜观察发现,小径木落叶松的径壁具缘纹孔数目较多,且多具纹孔膜,小径木落叶松除在树脂道中含有树脂外,在一部分管胞胞腔内以及一些木射线细胞中也含有树脂,在产生缺陷的小径木落叶松锯材中,连续加热方式下锯材的开裂缺陷最为严重,波动2时次之,波动6时几乎没有开裂现象;小径木大青杨心材导管中的层状浸填体含量较多,且径壁具缘纹孔较为密集,管间纹孔呈互列方式,绝大多数纹孔具有纹孔膜,干燥后的小径木大青杨锯材均有不同程度的皱缩现象产生,其中连续加热干燥试验锯材的皱缩现象最严重,波动2时次之,波动6时干燥试验锯材的皱缩缺陷最小。
