摘 要:马峦山地区位于广东深圳东北部,地理位置为北纬22°37'~22°39',东经114°17'~114°22',周围林地面积达上百平方千米.本研究对马峦山地区种子植物区系131科482属907种进行分析,结果表明:(1)表征科主要为樟科、芸香科、鼠刺科、山茶科、含羞草科、桃金娘科、五加科、桑科、藤黄科和五列木科、壳斗科、省沽油科、山矾科、安息香科、金缕梅科、杜鹃花科、买麻藤科等.(2)属的地理成分多样,以热带亚热带成分占绝对优势,热带分布、热带至亚热带分布的科、属分别占总科数的85.72%、总属数的86.67%.(3)区域特有现象明显:中国特有属5属,含6种;亚洲热带-亚热带特有属11属,含16种;东亚特有属14属.(4)马峦山种子植物区系与邻近的尖峰岭、内伶仃岛、南岭、香港、黑石顶区系比较,科的相似性指数分别是95.19%、70.19%、89.42%、95.19%和92.31%;属的相似性指数分别为87.55%、57.17%、69.20%、94.13%和72.78%.Maluanshan Mt. region is located at 22°37'~22°39',N114°17'~114°22' E,the northeast Shenzhen City in Guangdong province,and covered acreage more than 100 km^2. There are 907 species belonging to 131 families and 482 genera in this rich hiodiversity place. A detail floristic analysis showed: (1) The dominant and typical families mainly are Lauraceae, Rutaceae, Escalloniaceae, Theaceae, Mimosaceae, Myrtaceae, Araliaceae, Moraceae, Guttiferae, Pentaphylacaceae, Fagaceae, Staphyleaceae, Symplocaceae, Styracaceae, Hamamelidaceae, Ericaceae,and Gnetaceae. Most of these families are also characteristic elements of south China and Cathaysian Flora. (2) Genus geographical elements are predominanent by tropical and subtropical distribution,among them,families are up to 85.72% of the total,genera are up to 86.67% of the total; (3) With obvious local endemism, e. g. the genera endemic to China is 5 genera and 6 species,i, e. Tutcheria , Sargentodoxa , Semiliquidamba , Did ymostigma and Cunninghamia ; tropical-subtropical genera endemic to Asia is 11 genera and 16 species, e. g. Schima,Reevesia, Bischofia, Phyllodium,Altingia, Eustigma ,Rhodoleia, Heteropanax, Sinosideroxylon, Alniphyllum, Pottsia ; Genera endemic to East Asia is 14, e. g. Houttuynia, Actinidia, Rhaphiolepis, Euscaphis, Eleutherococcus, Enkianthus, Ainsliaea, Hemiste ptia ,Youngia , Perilla , Aspidistra, Liriope , Ophiopogon, and Ph yllostach ys. (4) Compared with floras of Jianfengling Mt in Hainan Island, Neilingding Island, Nanling, Hong Kong and Heishiding in Guangdong province,the similarity index of families shared with the above regions are 95.19 %, 70.19 %,89.42%,95. 19%,and 92.31%;and the similarity index of shared genera are 87.55%,57.17%,69.20%, 94.13%,and 72.78%.
