西藏林芝地区木本园林植物引种研究

Research about the Woody Landscape Plants' Introduction in Linzhi Preferecture of Tibet

西藏林芝地区地理环境特殊,以往绿化中园林苗木应用种类少。结合“福建公园”绿化工程,从内地引种59种木本园林植物,对其成活率及长势进行了4年的观察研究。从引种苗木的长势、观赏特性保持度来看,本次引种生长表现良好的植物有紫叶李、四照花等32种,生长表现一般的植物有水杉、白玉兰等8种,生长表现不佳的植物有银杏、桂花等14种,全部死亡的有合欢、木芙蓉等5种。并对影响西藏林芝地区木本园林植物引种的关键因子进行了探讨,其关键因子主要为风害和低温。

Accompanied by 'Fujian Park' landscape engineering, 59 species woody landscape plants have been introduced in from backland. A four-year observation and research have been done on their survival rates and growth vigor. In this introduction, in view of the growth vigor and the appreciative characteristics'degree of retentivity there are 32 well-growing species, 8 normal-growing species, 14 poor-growing species, and 5 fully-died species in this introduction plants. This paper has also discussed the key factors which work on the woody landscape plants'introduction in Linzhi prefecture of Tibet.
