乡土木本植物在杭州园林植物群落营建中的应用

Application of Native Woody Plants in Construction of Plant Communities in Hangzhou Landscape

城市园林绿地中乡土植物的应用及其群落构建是体现地方特色景观的重要途径,也是建设节约型园林的必由之路。以杭州西湖风景名胜区环湖老公园与钱江新城、下沙新城新建公园的乡土木本植物为对象,研究杭州城市园林植物群落的种类组成、群落结构特征。结果表明:目前杭州园林植物群落中存在物种组成简单,乡土木本植物种类偏少、配置结构不合理等问题,特别是近年新建公园问题更加突出。针对这些问题及杭州市自身的特点,重点推荐具有观赏价值和应用前景的乡土木本植物种类,并提出构建杭州地域特色节约型园林的建议。

An important way to reflect local landscape characteristics is to apply native plants and build local dominant plant communities in urban green spaces.This is also the only way to build conservationoriented landscape.This paper analyzes the species composition and community structure characteristics of native woody plants of plant communities of some old parks around the West Lake and some new parks in the Qianjiang New City and the Xiasha New City in Hangzhou.The results show that the existing problems in those plant communities are as follows:1)the species composition is simple;2)native woody plant species are few;3)configuration structure is irrational.Those problems are especially prominent in the new parks.Aiming at these problems and local characteristics of Hangzhou,the paper introduces some native woody plant species which have ornamental value and application prospects,and proposes a series of recommendations to build conservation-oriented landscape with the local feature of Hangzhou.
