摘　　要：在开展植物调查研究的基础上,对梅江流域的植物区系、稀濒危植物、城区古树(名木)植物、植物多样性保护的层次((物种、群落、自然保护区)及保护对策进行了的论述.结果表明:(1)本流域共有高等植物231科874属2268种(包括种下等级),其中,蕨类植物28科52属88种,裸子植物7科13属21种,被子植物196科809属2159种;(2)植物区系以热带成分(热带美洲、热带非洲和热带大洋洲)占绝对优势,但同时又较多的温带成分,这种热带—温带过渡性质也就是南亚热带地区的特点;(3)流域现有各类珍稀濒危植物28科37属43种,梅州城区现有古树29科49属55种,计407株.The plant flora,rare and endangered plants,old trees/famous trees in urban area,gradation（species,coummunity and nature reserve） of plant diversity ＆ protection countermeasure were discussed on the basis of plant investigation in Meijiang basin.The chief results were as follows：（1） There were 231 families,874 genera and 2268 species,of which 28 families,52 genera and 88 species were ferns,and 7 families,13 genera and 21 species were gymnosperms,and 196 families,809 genera and 2159 species were angiosperms;（2） The flora of plants took on the transitional characteristics from tropics to temperate zone,namely characteristics of plant flora in the south subtropics——tropic ingredient occupied absolute advantages but temperate ingredient too occupied relative ratio;（3） The rare and endangered plants had 28 families,37 genera and 43 species,and the old trees 29 families,49 genera and 55 species,totally 407 trees in urban area.
