本文进行了盖杨、辽宁扬、辽河杨的优良特性比较。结果表明，盖杨生长速度快，5年生单株村积生长量较辽宁杨高出7．40％～40．90％（盖州试验林除外），较辽河杨高出9．1％～38．2％；盖杨材质优良，气干密度分别为辽宁杨、辽河杨的106．31％、117．04％，基本密度为辽宁扬、辽河杨的107．75％、116，48％；木材纤维长宽比的大小是造纸纤维质量的重要指标，盖杨为48．65，大于辽宁杨和辽河杨。盖杨是速生丰产林和纸浆林的优良品种。
In this paper, Gaiyang, Liaoning Yang, Liaohe Yang superior characteristics comparison. The results showed that the growth of G. capitata was faster and the annual growth of 5-year-old per plant was 7.40% -40.90% higher than Liaoning’s (except for Gaizhou experimental forest), 9.1% ~ 38% higher than that of Liaohe .2%. The quality and drying density of Gailoung were 106.31% and 117.04% of the Poplar and Liaohe Poplar in Liaoning respectively. The basic density was 107.75% and 116.48% Fiber aspect ratio is an important indicator of the quality of papermaking fibers, the cover is 48.65, more than Liaoning and Liaohe Yang. Gai Yang is a fast growing and high-yield forest pulp fine varieties.
