摘　　要：以生长在3种长江滩地类型(江滩、洲滩、湖滩),3种栽植密度(3 m×4 m、4 m×5 m、5 m×6 m)下的3个品系速生人工林杨树木材[欧美杨无性系72杨(Populus×euram ericacv.I-72/58)、美洲黑杨无性系63杨(P.deltoidescv.I-63/51)和69杨(P.deltoidescv.I-69/55),以下简称72杨、63杨和69杨]为对象,在分析不同培育措施条件下人工林杨树木材材性的基础上,根据最终用途对杨树材性的要求进行评价,从而提出适宜于不同最终用途的最佳培育措施。结果表明,长江滩地杨树用于作建筑类材时,63杨和69杨为相对适用于作建筑类材的品系,3m×4 m是培育建筑类材的最佳栽植密度;对于纸浆材来讲,洲滩上宜选择63杨,江滩和湖滩上宜选择69杨在4 m×5 m栽植密度下培育;对于单板类人造板材来讲,宜选择72杨和69杨以3 m×4 m栽植密度来培育。Three kinds of fast growing poplar, poplar 72 （ Populus × euramericana cv. I-69/58 ）, Poplar 63 （ Populus deltoides cv. I-63/51 ）, Poplar 69 （ Populus deltoides cv. I-69/55 ）, grown in three different beaches of Changjiang river （river beach, islet beach and lake beach） with three different planting density （3 m × 4 m, 4 m × 5 m, 5 m ×6 m） were selected as the materials. Based on analyzing the wood properties of poplar in different forest cuhures, the best silviculture are revealed according to the end-use of wood products. The resuhs show that poplar 63 and poplar 69 grown in the lake beaches with spaces of 3 m × 4 m are suitable relatively for the use of structural wood. Poplar 63 grown in the islet beaches＇ and poplar 69 grown in the river and lake beaches with the spaces of 4 m × 5 m are suitable for pulp and paper use. Poplar 72 and poplar 69 with the spa.ees of 4 m × 5 m grown in the beaches of Changjiang river are suitable for t.he artificial broads consisted of veneer.
