摘　　要：在连续３年测定比较几个不同树种的生理特性和树冠结构的基础上，本文对青檀的耐荫性进行了初步分析，结果表明，青檀的耐荫性随年龄的增大而降低，１２年生以前，青檀是耐荫的；１３至２５年生之间，青檀是喜光树种；２６年生以后青檀则逐渐变为阳性树种。比较的结果还表明，青檀的耐荫性较马尾松强，较杉木弱，从总体看属中偏阳树种。The shade endurance of Pteroceltis tatarinowii was studied by comparison ofthe physiological property and the crown structure of different tree species. Results showedthat the older the age of the plant was, the weaker the shade endurance of it was.While theplant was shade tolerant under 12 years of age, it becanie heliophilous from the 13th year tothe 25th year, and was a sun tree after 26 years of age. Generally, the shade endurance ofP. tatarinewii was stronger than that of Pinus mossoniana but weaker than that of Cunning-hamia lanceolata.
