Plant community of Lishui ecological demostrative area

丽水生态示范区自然环境优越 ,植被保存良好 ,动植物资源丰富 .根据对丽水山地的植被调查 ,勘明该生态示范区内植被和群落类型主要有针叶林、针叶阔叶混交林、常绿阔叶林、常绿落叶阔叶混交林、落叶阔叶林、山地矮林、山地灌丛草丛、竹林等 8大类共 1 1 4种 .丽水山地群落的垂直分布分层特征较明显 ,总的可分为三个层次 :海拔 80 0 m以下以暖性针叶林、栲类林等为主 ;海拔 80 0～ 1 3 0 0 m山地以温性针叶林、甜槠木荷林等为主 ;海拔 1 3 0 0 m以上则为常绿落叶阔叶混交林、针阔叶混交林、山地灌丛。

According to the investigation data in the area, the paper shows that there are 8 types and 114 kinds of plant communities. They are coniferous forest, mixed needle broad-leaved forest,evergreen broad-leaf forest, evergreen and deciduous broad-leaf mixed forest, deciduous broad-leaf forest, montane low bush, montane scrub and grassland and bamboo forest. The characteristics of vertical zonality are obvious in Lishui mountain. The distribution at the altitude 800 m is warm-coniferous forest and Form. Castanopsis fargesii , at the altitude of 800～1300 m temperature-coniferous forest and Form. Castanopsis eyrei-Schima superba, and at the altitude above 1300 m evergreen and deciduous broad-leaf mixed forest, broad-leaf and coniferous mixed forest, scrub and grassland.
