摘　　要：选择近年来引进的洞庭湖区造林的丹红杨、巨霸杨、南林-95杨、南林-895杨，于2004年春在西洞庭目平湖外滩进行对比造林试验，经4年观测，其造林保存率均低于78％。丹红杨、巨霸杨胸径生长量较大；巨霸杨、丹红杨、南林-895杨的材积生长量较南林-95杨增产15．9％～25．6％。各项生长量指标在4个无性系之间均无显著差异。On recently years,Populus clones＂Danhong＂ ,＂Juba＂ ,NL-95 and NL-895 were introduced into Dongting Lake for plantation. The contrast test of forestation was based on beaches of Muping Lake of west Dongting Lake from spring of 2004. The preservation rate of forestation were all less than 78% by observation for four years. The growth of stem diameter of＂Danhong＂, ＂Juba＂were better; the wood growth of ＂Danhong＂, ＂Juba＂, NL-895 increase more 25.6% - 15.9% than NL-95. The each growth volume indexes weren＇ t remarkably different among the four clones.
