Floristic Study in Maofengshan Forest Park,Guangzhou

This paper is a preliminary analysis on the flora in Maofengshan Forest Park(MFSFP).MFSFP is located at the northeastern of Guangzhou City,at latitude 23°16′9″-23°19′26″N and longitude(113°22′5″-113°)29′32″E,with a total area of 5362hm~2.The highest peak is 534.9m.In MFSFP,according to our collection and identification,there are 610 species of wild vascular plants(including infraspecific taxa),belonging to 146 families and 398 genera.The dominants of the forest community are mainly of the following families: Lauraceae,Moraceae,Theaceae,Fagaceae,Myrsinaceae,Rutaceae,Hamamelidaceae and Aquifoliaceae.According to the geographical distribution patterns.375 genera of the spermatophyte can be divided into 13 types and 12 subtypes.In the flora,the elements of tropical-subtropical genera are more abundant(80.21%).Tropical and temperate floristic elements have similar effects on the MFSFP.In this paper,the problem of dealing with the floristic assignment in MFSFP are discussed.The authors argue that the MFSFP flora should be a part of theAustro-Cathaysia Region,belonging to the Paleotropical Kingdom.
