摘要
以海南省南渡江流域两侧一定范围内的自然植被作为研究对象,采用线路调查和样方调查相结合的野外植被调查方法,对该区域自然植被的物种组成、自然植被类型与主要群落特征进行调查分析。结果表明:南渡江流域共记录到维管植物515种,隶属于122科357属,其中双子叶植物占绝对优势,呈现明显的热带植物区系性质特点。将南渡江流域自然植被划分为3个植被型组、6个植被型和24个群系。中上游多分布低山地热带季雨林、常绿季雨林、半落叶季雨林等植被类型,下游滩涂地多分布为岸灌丛、滩灌丛和草地。
Taking a certain range of the natural vegetation which on both sides of Nandujiang Basin in Hainan Province as the re -search object ,using the line survey and quadrat survey combined field vegetation survey methods ,this paper selected the natural veg-etation species composition ,vegetation types and main community characteristics for survey and analysis .The results showed:it re-corded 515 species of Vascular plants which belonged to 122 families and 357 genera,and the dicotyledonous plants hold the absolute advantage among them ,which embodying the obvious characteristics of tropical flora .The natural vegetation within the scope of the investigated NanDuJiang Basin were divided into 3 vegetation type groups ,6 vegetation types and 24 formations.The mid and up stream were divided into the tropical monsoon forest ,evergreen monsoon forest ,and half deciduous monsoon forest vegetation types , the downstream shoal land was divided into the bank thickets ,beach scrub and grassland .
