杭州钱江新城CBD公园植物景观研究

Study on Plant Landscape of Hangzhou Qianjiang New Town CBD Park

通过现场踏勘和典型样地法,对杭州新地标钱江新城CBD公园植物景观进行调查,并对其植物多样性和植物群落结构作了相关分析。结果表明,钱江新城CBD公园现有种子植物60科85属108种(含种以下等级),植物种类比较丰富,其中乔灌草、常绿与落叶乔木、常绿与落叶灌木种类比例较为合理,植物景观表现多样;植物群落结构以复层混交型为主,主要包括落叶阔叶林、常绿阔叶林、常绿落叶阔叶混交林3类,季相景观和生态性较为明显;积极可进入型、消极可进入型、不可进入型3个类型植物空间,分别占22.2%、16.7%、61.1%,绿地空间类型多,但对城市公园来说,可进入型空间比不可进入型空间更重要,应适当增加可进入型植物空间来满足钱江新城CBD公园人口相对集聚性特点。

Through field survey and typical sample-plot method , plant landscape of Qianjiang New Town CBD in Hangzhou park was investigated , and plant diversity and community structure were analyzed .The result showed that there were 108 plant species under 60 families and 85 genera in this CBD park .Plant richness was relatively high and plant landscape was diversity .The species proportion of tree , shrub and herb was reasonable , and the propotion was also reasonable between evergreen trees and deciduous trees , between evergreen tree and deciduous shrubs .The structure of plant community , which was dominated by mixed type and multiple layer , was classified into 3 types, namely the deciduous broad-leaved forest, evergreen broad-leaved forest, and mixed forest of evergreen and deciduous broad-leaved, and it was characterised by seasonal landscape and ecological feature .Different types of green plant spaces , namely positively accessable type , negatively accessible type and un-accessible type, accounted for 22.2 %, 16.7 %, and 61.1 % respectively.For city parks, however, accessible type is more important than un-accessible type , and the portion of accessible type should be increased to meet the need of population agglomeration in Hangzhou CBD park .
