| Urban parks are the main places for urban residents to take recreation activities.As an important part of urban parks,the rationality and scientificity of plant landscape directly affect the recreational behavior of urban residents.In order to optimize the plant landscape of urban parks and meet the needs of recreation behavior,this study took Xiaoyaojin Park in Hefei as the research object,selected 30 quadrats in the park to investigate the characteristics of plant landscape,recreation behavior,recreation satisfaction and preference,and comprehensively analyzed the plant landscape and recreation behavior by using the methods of principal component analysis,variance analysis,correlation and stepwise regression analysis.The influences of plant landscape characteristics on recreation behavior were discussed in depth,and suggestions were put forward to optimize plant landscape in urban parks,so as to construct high-quality urban parks suitable for recreation needs of urban residents.The results are as follows:(1)Plant landscape characteristics: Quadrat 10 had the highest overall score(1.969),Quadrat 12 had the lowest score(-3.053).In terms of plant diversity characteristics,Quadrat6 and Quadrat 10 had the highest plant richness,and Quadrat 10 had the highest diversity index(1.193).In terms of ornamental characteristics,foliage plants were the most common among ornamental elements,spring plants accounted for the largest proportion in ornamental seasons,and red plants were the most common in ornamental color system.In terms of plant landscape structure characteristics,the combination of arbor,shrub and grassland accounted for the largest proportion.In terms of plant space characteristics,semi-open space is the most.In terms of site characteristics,Quadrats 2 and Quadrats 30 have the largest green area(400square meters).(2)The number of four types of recreation behaviors in spring and autumn from high to low was: ornamental recreation behavior,recreational recreation behavior,sports recreation behavior,and cultural recreation behavior.There were significant differences between the recreational recreation behavior and ornamental recreation behavior in spring and autumn.There were no significant difference between sports recreation behavior and cultural recreation behavior in spring and autumn.(3)The preference for plant landscape characteristics from high to low was: ornamental characteristics,plant landscape structure,and plant landscape spatial characteristics;The preference of tourists for different ornamental characteristics of plant landscape from high to low was plant color,plant ornamental elements,and plant seasonal characteristics;In terms of plant seasonal preference,the highest was autumn,spring,summer and winter;The plant color preferences of the recreational participants ranged from high to low as red,yellow,green,blue-purple and white;The spatial preferences of tourists for plant landscape from high to low were: semi-open space,open space,covered space,vertical space,and closed space.(4)The spatial characteristics of plant landscape have significant positive effects on recreational behavior.Species richness has a significant positive effect on recreational behavior.The number of color system and the characteristics of the site have a significant negative effect on the sports recreation behavior.Site characteristics have a significant negative impact on cultural recreation behavior. |
