摘要
浙江西天目山自然保护区是植物宝库,在不同海拔区间有不同类型的球根植物分布。采用线路调查法,对浙江西天目山自然保护区海拔330—1230 m范围内的球根植物进行了调查。主要结果如下:(1)在海拔330—1230 m范围内共发现24种球根植物,隶属11科。其中单子叶植物共8科21种,双子叶植物共3科3种;(2)随着海拔高度的升高,球根植物的类型明显减少,而部分物种种群数量增加;(3)在海拔330—530 m范围内,共分布球根植物20种,其中百合科植物为优势种;(4)海拔530—1230 m范围内,共分布植物10种,其薯蓣科、天南星科为优势种。根据以上结果,同时结合球根植物的生长习性与观赏价值,认为调查发现的天目山球根植物中共14种可用于园林绿化,其中部分植物也是重要的切花材料。
The West Tianmu Mountain Nature Reserve in Zhejiang Province is a plant treasury.There are different types of bulbous plants in different altitudes.Having a good grasp of their distribution characteristics at different altitudes will be helpful to explore the wild bulbous plant resources within these area,and provide theoretical reference for their application in landscape greening.In this article,the bulbous plants in the 300—1230 m altitude range of the West Tianmu Mountain Nature Reserve were investigated by line survey.The results were as followed:(1)A total of 24 species of bulbous plants belonging to 11 families were found in the range of 300—1230 m above sea level.Among them,21 species belong to 8 families and 3 species belong to dicotyledons;(2)With the increase of altitude,the type number of bulbous plants decreases clearly while the number of some species increases;(3)A total of 20 species of bulbous plants are distributed in the altitude range of 330—530 m,of which Liliaceae is the dominant species;(4)In the altitude range of 530—1230 m,there are 10 species of plants distributed in the region,and the dominant species are Dioscoreaceae and Araceae.Based on the above results,combined with their growth habits and ornamental value,it can be inferred that 14 species of bulbous plants in west Tianmu Mountain can be used for landscape greening,and some of them are also the important cut flower materials.
