贾鲁河沿线乡土植物调查及在园林中应用的研究

Investigation of native plants along Jialu river and their application in gardens

为掌握贾鲁河沿线乡土植物资源及园林应用现状,从而为贾鲁河下阶段建设提供参考,同时也为类似的城市滨河绿地建设提供参考依据,本文通过对郑州市贾鲁河尖岗水库至郑开大道段约50km长度范围内的滨河绿地园林植物资源实地调研,从生长类型、观赏特色、群落组成和植物应用方面进行了分析。结果表明:郑州市贾鲁河园林植物约68科131属212种,其中乔木层植物86种,灌木层植物71种,草本植物55种;观花植物、观果植物、观叶植物、观形植物分别占贾鲁河滨河绿地园林植物种类的60.38%、19.34%、37.74%和29.72%;贾鲁河滨河绿地园林植物组成人工植物群落和半人工植物群落。因此,贾鲁河滨河绿地园林建设时须进一步优化乔灌木种类的比例,加强乡土植物应用,丰富植物群落结构,注重植物色彩搭配。

In order to grasp the local plant resources and landscape application status along the Jialu River,and provide reference for the next phase of construction in Jialu River,as well as for similar urban riverside green space construction,this paper analyzes the growth type,ornamental characteristics,community composition and plant application by investigating the riverside green space landscape plant resources within 50km from Jiangang Reservoir to Zhengkai Avenue in Jialu River,Zhengzhou.The results show that there are 212 species of garden plants belonging to 131 genera and 68 families in Jialu River,including 86 species of arbor layer plants,71 species of shrub layer plants and 55 species of herbaceous plants.Ornamental plants,fruit plants,leaf plants and shape plants account for 60.38%,19.34%,37.74%and 29.72%of the garden plant species in riverside greenbelts in Jialu River respectively.Garden plants in riverside greenbelts in Jialu River are composed of artificial plant communities and semi-artificial plant communities.Therefore,it is necessary to further optimize the proportion of arbor and shrub species,strengthen the application of native plants,enrich the plant community structure,and pay attention to the collocation of plant colors in the construction of riverside green space gardens in Jialu River.
