广东省自然植被类型划分的探讨-针叶林

DIVISION OF NATURAL VEGETATION TYPE IN GUANGDONG PROVINCE: THE CONIFEROUS FOREST

摘要:

广东省自然植被分类系统的建立,是借助包括地理信息系统(GIS)、全球定位系统(GPS)与遥感(RS)等3S技术来绘制数字化植被类型分布图的基础。我们提出的广东省自然植被的分类方案及阿拉伯数字编码植被类型的方法,是在前人有关广东省植被分类的各种不同观点的基础上的一种探索,初步将广东陆生植被划分为5个植被型组,即针叶林、阔叶林、竹林、灌丛、草丛；并详细探讨针叶林植被型组的分类系统,将其划分为2个植被型4个植被亚型,即(1)暖性针叶林:①亚热带常绿针叶林；②亚热带落叶针叶林；③亚热带针阔叶混交林；(2)热性针叶林:④热带常绿针叶林；进一步则划分出14个群系,并列出各群系下较具代表性的群丛。

Abstract:

Various classification systems of vegetation in Guangdong Province had been proposed for specific purposes. They are not completely suitable for the purpose of mapping digitized vegetation distribution with the assist of geographic information system, global position system and remote sensing. The author proposes a new scheme for the division of vegetation type in Guangdong Province. In this paper, a complete list of coniferous forest in Guangdong is presented, viz. 2 vegetation types, 4 sub-vegetation types and 14 vegetation formations and their representative associations： 1．Warm coniferous forest：(A)Subtropical evergreen coniferous forest：(a)Formation Pinus massoniana；(b)Formation Cunninghamia fanceolata；(c)Formation Pinus kwangtungensis；(d)Formation Tsuga longibracteata；(e)Formation Podocarpus nagi；(f)Formation Fokienia hodginsii；(B)Subtropical deciduous coniferous forest：(g)Formation Glytostrobus pensilis；(h)Formation Taxodium distichum；(C)Subtropical needle-broad 1eaves mixed forest：(i) Needle-broad 1eayes mixed forest dominated by Pinus massoniana；(j)Needle-broad 1eaves mixed forest dominated by Cunninghamia janceofata；(k)Needle-broad 1eaves mixed forest dominated by Podocarpus fleuryi；(l)Needle-broad leaves mixed forest dominated by Pinus kwanotungensis；(m)Needle-broad leaves mixed forest dominated by Tsuga tongibracteata；2. Hot coniferous forest：(D)Tropical evergreen coniferous forest；(n)Formation Pinus latteri.
