摘　　要：以许昌市饮马河北段为研究对象,实地普查了该滨河景观带的物种组成与生长特性,并以i-Tree Eco模型评价树木的净化空气、固碳、释氧、雨水截留等生态效益,也尝试评估地被植物与水生植物的生态效益。结果表明,(1)研究区共有70种园林植物,其中树木36种8 951株,优势树种有白蜡、银杏、水杉等。(2)研究区树木年总生态效益为97.62万元,以碳储存(56.44万元)和产氧(18.36万元)为主,单株平均生态效益较高的有杨树、枫杨、馒头柳、苦楝等。(3)地被植物固碳、产氧、滞尘等的生态效益共111.97万元,湿地气候调节、固碳、水质净化等的生态效益共7.89万元。期望本研究为城市滨水景观的植物配置与优化提供参考。Taking the northem section of the Xueyuan River in Xuchang City as research objects,this paper investigated the species composition and growth characteristics,and evaluated the ecological benefits of trees such as air purification,carbon sequestration,oxygen release and rainwater retention using the i-Tree Eco model.Further,the ecological benefits of ground cover and hydrophyte were also evaluated.The results showed as follows,(1)in the study area,there were 70 garden plant species including 36 tree species and 8951 individuals,which were dominnanted by ash,ginkgo,metasequoia.(2)The annual total ecological benefit of trees was 976200 yuan,with carbon storage(564400 yuan)and oxygen production(183600 yuan)as the main source,and the average ecological benefits of poplar,maple poplar,mantou willow,and neem were in the front rank.(3)The ecological benefits of carbon fixation,oxygen production and dust retention by ground cover plants totaled 1119700 yuan,and the ecological benefits of wetland climate regulation,carbon fixation and water purification for hydrophyte totaled 78900 yuan.It is expected that this study will provide reference for planting design and optimization of urban waterfront landscape.
