Abstract:
The tree stratum of typical natural forest of Sloanea sinensis is stratified obviously to 3 strata(stratum I,stratum II and substratum III).The height of the Maximum Light Receiving Plane(MLRP) is 16.5 m.The forest is composed by 50 tree species and the important value of Sloanea sinensis is 16.07%. There are 11,15 and 38 tree species in stratum I,stratum II and stratum III respectively.There are many rare or high-value timber species,such as Schima superba,Cinnamomum chekiangense,Tsoongiodendron odorum,Parakmeria lotungensis,Nyssa sinensis,Michelia fujianensis,Prunus spinulosa,Michelia maudiae and Engelhardtia fenzlii.Its species richness(R),Shannon-Wiener index(SW),evenness(E) and ecological dominance(ED) in tree stratum are 50,4.56,0.81 and 0.09 respectively,which in stratum I are 11,3.03,0.88 and 0.16 respectively,in stratum II are 15,3.23,0.83 and 0.17 respectively,in stratum III are 38,4.30,0.82 and 0.09 respectively.Its average stand DBH,height,density and growing stock in tree stratum are 26.1 cm,28.06 m,912 N/hm2 and 590.58 m3/hm2respectively.Its percentage of stand density in stratum I,stratum II and stratum III are 10.1% 20.6% and 69.3% respectively.Its percentage of growing stock in stratum I,stratum II and stratum III are 75.8%,18.1% and 6.1% respectively.
Key words: Sloanea sinensis, natural forest, stand characteristics, tree species composition, species diversity
