西藏引种樟子松造林可行性分析

Feasibility Analysis on Introduction of Pinus sylvestris L.vas.mongolica Litv to Tibet

通过分析樟子松天然分布区、成功引种区及西藏主要人工造林区的气候生态指标和樟子松生长的土壤条件,结果表明:除阿里地区因降雨量不足,空气相对湿度小不宜引种外,拉萨市、山南市、日喀则市的降雨量、空气相对湿度、平均温度、极端温度、光照、风速等气候生态指标,以及土壤条件均能满足樟子松生长发育的需求,引种樟子松是可行的。

Through comparing the climatic ecological indexes and soil conditions in natural distribution area, successful introduction area of Pinus sylvestris L.vas.mongolica Litv with main artificial afforestation region in Tibet, the results showed that Pinus sylvestris L.vas.mongolica Litv adapted to the climatic ecological indexes including rainfall, relative humidity, mean temperature, extreme temperature, light and maximum wind speed and soil conditions in Lhasa, Xigaze and Shannan Cities except Ngari Prefecture.So introduction of Pinus sylvestris L.vas.mongolica Litv to Tibet was feasible.
