Abstract

The tree stratum of 34- year-old Schima superba forest by AMPR(Artificial Measures Promoting Regeneration) was stratified obviously to 2 sub-strata(sub-stratum I and sub-stratum II) by MLRP(Maximum Light Receiving Plane) method.The tree height in sub-stratum I was higher than or equal to 16.5 m.It was typical S.superba community which was composed by 33 tree species and the important value of S.superba(the dominant tree species) was 26.68%.There were 8 and 30 tree species in sub-stratum I and sub-stratum II respectively.The important value of S.superba(the absolutely dominant tree species) in sub-stratum I was 49.77%.Its species richness(R),Shannon-Wiener index(SW),evenness(E) and ecological dominance(ED) in tree stratum were 33,4.37,0.87 and 0.08 respectively.Which in sub-stratum I were 8,2.40,0.48 and 0.26 respectively and in sub-stratum II were 30,4.41,0.88 and 0.06 respectively.Its average stand DBH,height,density and growing stock in tree stratum were 14.2 cm,18.4 m,1 875 N/hm2 and 262.9 m3/hm2 respectively.Its average stand DBH in sub-stratum I and sub-stratum II were 23.9 cm and 9.6 cm respectively.Its average stand height in sub-stratum I and sub-stratum II were 21.9 m and 12.1 m respectively.Its percentage of stand density in sub-stratum I and sub-stratum II were 23.0% and 77.0% respectively.Its percentage of growing stock in sub-stratum I and sub-stratum II were 75.2% and 24.8% respectively.
