闽西北山区几种阔叶树种造林效果评价研究

在福建三明市梅列区陈大镇棕南进行山乌桕等24个乡土阔叶树种山地造林对比试验,4年生结果显示,24个树种间的造林成活率、树高、胸径、冠幅生长量均存在极显著差异,表明山地造林成功的关键技术之一是树种选择。24种乡土阔叶树种的高生长与胸径（地径）生长均表现出极显著的正相关（P〈0.0001）。根据各树种的造林成活率与生长量的综合表现,山乌桕、枫香、山杜英、拟赤杨、石栎、木荷、杨梅在山地造林表现较优,可作为当地营造水土保持林、水源涵养林等生态公益林的首选树种。

A Study of Effectiveness of Broadleaf Species Afforestation in Mountain Regions of Northwest Fujian Province

24 indigenous broadleaf tree species were planted in order to select the excellent ones for ecological forestation in the area of Meilie.The result showed that the survival percentage,height growth,diameter growth and range of tree crown of different species were highly significantly different,indicating that the key technique for the plantation in such areas was the selection of the tree species.Besides,the height growth had a significant correlation with the diameter growth（P0.001） for the all 24 tree species.By comprehensive assessing the growth traits among these tree species,the following tree species were suggested for the establishment of ecological forest：Sapium discolor,Liquidamber formosana,Elaeocarpus sylvestris,Alniphyllum fortunei,Lithocarpus glaber,Schima superda and Myrica rubra.
