摘要
浙江柿(Diospyros glaucifolia Metc.)为优良速生用材树种,通过样地调查、统计分析等方法,对浙江西天目山浙江柿群落种类组成及结构、区系特点、大小级结构等进行研究。结果表明,群落中植物成分丰富,植物区系具有热带起源性,有从热带向温带过渡的性质;群落结构较复杂,层次明显,浙江柿在乔木层具有最高的重要值,为优势种;郁闭度较大的P1种群有衰退的趋势,位于山坡疏林的P5种群为增长型,而P2、P3、P4、P6种群较不完整。
Diospyros glaucifolia is an excellent fast -growing timber plant. The composition and structure, flora characteristics and size structure of D. glaucifolia in Xitianmu Mountain were studied by field investigation and statistical analysis. The results showed that it was abundant in plant species and its flora originating from tropical changed to temperate. The community structure was complicated, containing obvious and different lays. D. glaucifolia is the dominant species with the highest importance value. Population P1 with higher canopy density showed a declining trend. Population P5 in open forest of the hillside showed a growing tendency. Then the structures of population P2,P3, P4 and P6 were incomplete.
