摘要
马尾松天然林、杉木人工纯林、柏木和杉木人工混交林是亚热带地区常见的森林植物群落,乔木层可划分为3个亚层:第1亚层高15 ～ 18 m,第2亚层高9 ～ 15 m,第3亚层高3 ～ 9 m.灌木层中有许多物种经培育可成大材、良材的阔叶树萌蘖丛,其物种较丰富.组成天然马尾松林物种9种,杉木人工纯林11种,柏木和杉木人工混交林物种20种.灌木层的物种多样性指数高于乔木层和草本层,由檵木﹑映山红﹑白栎﹑乌饭﹑盐肤木﹑山柿、青冈栎、冬青、枫香﹑红楠﹑野桃﹑香港黄檀木等组成,草本层以芒萁﹑五节芒等组成.
Natural Pinus massoniana forest, pure artificial Cunninghamia lanceolata forest and mixed forest of Cupressus funebris and C. lanceolata is common forest community in subtropical area. The arbor layer could divided into three sublayers: the first one with height of 15-18m, the second one 9-15m and the third one 3-9m. Shrub layer was rich in species diversity. There were 9 species in natural P. massoniana forest, 11 species in pure artificial C. lanceolata one and 20 in the mixed forest. Species diversity index in shrub was higher than that in arbor and herb.
