昆明地区面山造林乡土树种的定量选择试验

Experiment of Quantitative Selection of Indigenous Trees for Afforestation in Visual Mountain Surface in Kunming Region

为筛选昆明地区绿化造林的优良乡土树种,于2003年5月在石林林场紫云林区设计了14个乡土树种的随机区组造林试验,包括5个重点区组,14个树种处理,于2007年2月进行调查.通过5年的观测调查,对14个参试树种的树高、地径、冠幅、冠高等的生长性状进行了分析研究,认为存在极显著差异.并用定量的方法筛选出冬樱花、石楠、麻栎、川滇桤木、旱冬瓜、云南杉等6个树种为入选乡土造林树种,并进行了讨论.
