惠州西湖风景区园林植物群落特征分析

Analysis on Garden Plant Community Character of Huizhou West Lake Scenic Area

为了弄清惠州市西湖风景区园林植物群落生长状况,加强西湖风景区的绿地景观建设,采用样方法对景区的33处绿地和12条景区道路的园林植物群落特征进行调查。结果表明:1惠州市西湖风景区园林植物共有139种,其中蕨类植物1科1属1种,裸子植物6科7属9种,被子植物58科108属129种。2应用频率和重要值较高的植物有红花羊蹄甲、细叶榕树、木棉、樟树、桂花、棕竹、红背桂、大叶油草、沿阶草、蜘蛛兰、白蝴蝶等。3经植物群落物种多样性分析表明,平湖景区的植物群落具有较高的物种丰富度和多样性,菱湖景区的物种丰富度和多样性则较低。因此,应加大对菱湖景区的改造,营造具有复合结构、层次丰富的植物群落。

In order to clarify the growth status of garden plant community and strengthen the construction of green land in Huizhou West Lake Scenic Area,33 green spaces and 12 scenic area paths in research area have been investigated by quadrat method. The results are as follows ：（1）139 kinds of garden plants have been gotten including Pteridophyte （1 family 1 genus 1 species）, Gymnosperm （6 families 7 genera 9 species） , and Angiosperm （58 families 108 genera 129 species）. （2）Bauhinia blakeana, Ficus microcar- pa, Bombax malabaricum, Cinnamomum camphora, Osmanthus fragrans, Rhapis excelsa, Excoecaria cochinchinensis ,Axonopus compressus, Ophiopogon japonicus ,Hymenocallis spciosa, and Syngonium podophyllum have high application frequency and important value. （3）The garden plant community biodiversity analysis indicated that the garden plant communities in Pinghu scenic area have higher species richness and biodiversity than that in Linghu scenic area. Therefore, Linghu scenic area should be improved by creating composite structure garden plant communities.
