摘 要

由于水热组合的不同,陆地植物群落生活型谱存在明显的地带性分异规律。比较不同群落的生活型谱就可以发现群落环境之间的差异。因此,通过运用不同的方法对聚宝山植被生活型的分析,与同纬度地区的生活型谱性比较,并对该地区的叶的性质进行分析,从而总结归纳聚宝山地区的群落的小气候等特征。所得结果如下:

(1)运用3种方法分析植被生活型可知,按照Raunkiaer 系统统计发现高位芽植物占绝对优势;按照神谷辰三郎分类方法分析可知旱生植物与木本植物占优势;按照《中国植被》生活型分类方法可知草本,木本,半木本以及叶状体植物所占比例相似,均得到较好发展。

(2)通过对3种植被生活型分类方法的比较发现,3种分类方法各有优缺点,可以相互补充。将三种方法综合分析发现:聚宝山群落的具有温热多湿的小气候特点,基本符合典型的亚热带常绿落叶阔叶混交林的群落特征。

(3)对聚宝山植物群落叶的性质的统计发现,中型叶、单叶、非革质叶、非全缘叶的种类是聚宝山植物群落的主要成员,反映出了聚宝山群落典型的亚热带常绿落叶阔叶混交林的群落外貌特征。

Plant Community Life-form Analysis in Jubaoshan Forest Park

ABSTRACT

Because of the different combination of hot and water, the life-form spectrum of terrestrial plant community had obvious zonal distribution rules. Comparing the life-form spectrum of different community, you can find the differences between the community environments. Therefore, with the analysis of the life-form and the nature of the leaf in mountain Jubao, comparing with other subtropical typical vegetation life-form spectrum, we can conclude the characters of the climate of it. The results are as follows:

(1)Using three methods to analyze the life-form of vegetation,we can get that: according to the statistics by Raunkiaer system, phanerophyte is dominant;according to the analysis by Shinya Buro classification method, xerophilous plants and xylophyta plants are dominant; according to lt;The Vegetation of China gt;life-form classification method, the proportions of herbaceous plant, xylophyta plants, half-xylophyta plants and thalloid plants are Similar, all of them get a good development.

(2)By comparing three kinds of classification methods of vegetation life-form, each method has advantages and disadvantages. Under the analysis of these three kinds of classification methods of vegetation life-form, we can conclude that mountain Jubao is in warm and humid climate and it is in line with subtropical typical vegetation life-form spectrum.

(3) According to the statistics of the nature of the leaf in Jubao mountain by Raunkiaer system, mesophyll, simple leaf, unleathery leaves and unentire leaves are the main members of the plant community in Jubao mountain. It is in line with the appearance of other subtropical typical.

Key words:Jubao mountain;Vegetation composition;Plant diversity;Life-form
