摘要：

55a生人促(AMRP)米槠林乔木层层次结构分化明显,应用最大受光面(MLRP)法可将乔木层明显划分为2个亚层。第Ⅰ亚层树高≥17.6 m。乔木层共有25种树种,米槠占绝对优势,重要值达150.96%,是典型的米槠单优群落,第Ⅰ亚层有7种树种,米槠占绝对优势,重要值达218.20%;第Ⅱ亚层有25种树种。乔木层物种丰富度S、多样性指数SW、均匀度E和生态优势度ED分别为25,2.92,0.63和0.29,其中第Ⅰ亚层分别为7,1.08,0.23,0.68;第Ⅱ亚层分别为25,3.95,0.85,0.10。全林平均胸径24.69 cm,平均树高23.11 m,株数密度1 208 株/hm²,单位面积蓄积量612.73 m³/hm²。第Ⅰ亚层和第Ⅱ亚层的平均胸径分别为32.84 cm和10.99 cm。第Ⅰ亚层和第Ⅱ亚层的平均树高分别为24.31 m和11.99 m。第Ⅰ亚层和第Ⅱ亚层的株数密度分布占全林的51.03%和48.97%,单位面积蓄积量分布占全林的94.46%和5.54%。

Abstract:

The 55a Castanopsis carlesii 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 17.6 m.It was typical mono-dominant community which was composed by 25 tree species and the important value of Castanopsis carlesii (the dominant tree species) was 150.96%.There was 7 and 25 tree species in sub-stratum I and sub-stratum II respectively.The important value of Castanopsis carlesii (the dominant tree species) in sub-stratum I was 218.20%.Its species richness (R),Shannon-Wiener index (SW),evenness (E) and ecological dominance (ED) in tree stratum were 25,2.92,0.63 and 0.29 respectively,with in sub-stratum I were 7,1.08,0.23 and 0.68 respectively,in sub-stratum II were 25,3.95,0.85 and 0.10 respectively.Its average stand DBH,height,density and growing stock in tree stratum were 24.69 cm,23.11 m,1 208 N/hm ² and 612.73 m³/hm² respectively.Its average stand DBH in sub-stratum I and sub-stratum II were 32.84 cm and 10.99 cm respectively.Its average stand height in sub-stratum I and sub-stratum II were 24.31 m and 11.99 m respectively.Its percentage of stand density in sub-stratum I and sub-stratum II were 51.03% and 48.97% respectively.Its percentage of growing stock in sub-stratum I and sub-stratum II were 94.46% and 5.54% respectively.

Key words: Castanopsis carlesii forest, forest characteristics, Maximum Light Receiving Plane (MLRP) method, Artificial Measures Promoting Regeneration (AMPR), species diversity
