Research On Spring Plant Landscape And Evaluation Of Universities In Hangzhou City

The campus green space is the main carrier of the study,development and life of the teachers and students.In recent years,with the rapid development of China's universities,the campus area has been greatly expanded,the campus green building has achieve sufficient attention.Hangzhou is the gathering place of Universities and Colleges in Zhejiang Province,the unique geographical and climatic environment in Jiangnan gave birth to the unique characteristic spring plant landscape,spring plant landscape of Universities in Hangzhou has become a beautiful scenery.This paper choose spring plant landscape from the eight campus five Universities in Hangzhou as the research object,on the basis of comprehensive field survey,46 typical quadrats are selected to record plant species,number,group plant configuration mode,and plant enclosed type space,in the quadrats analyze plant landscape attributes,functions and space,and evaluation the by plant landscape quality using the method of comprehensive evaluation.The conclusions are as follows:(1)The plant materials of spring landscape are rich and spring plant landscape in Hangzhou Universities is colorful.There are 352(contains the following grades)kinds of spring ornamental plants in the eight campus green space of five universities,flowering plants and foliage plants are the main plants.There are 220 kinds of flowering plants and 115 kinds of foliage plants,in which the high application frequency high mainly on species Rosaceae,Magnoliaceae,Caprifoliaceae,Aceraceae,Leguminosae,Berberidaceae and Oleaceae.Where in Magnolia denudata?Camellia japonica?Acer palmatum?Malus halliana and other tree occur in high frequency.It's characteristics of Jiangnan plant landscape is more obvious.And various Universities have different characteristics,such as the East Lake Campus of Zhejiang Agriculture and Forestry University planning and design plum garden,magnolia garden,rose garden and other garden,highlighting the spring of ornamental plants.Spring landscape along with the river in the xiangshan campus of China Academy of Art College choose Prunus Cerasifera ? Cerasus yedoensis ? Malus halliana ? Malus micromalus ? Prunus serrulata‘Lannesiana' and so on,the distribution on the basis of the spring plants blossom time series.Building the spring plant landscape of campus in colleges and universities discipline background and demand for landscape has a certain correlation between teachers and students.(2)The functionality of spring plant landscape in Hangzhou Universities is prominent,and the spatial types are diverse.The plant landscape space types in eight compus of five university include open space,half open space,closed space,covering space and vertical space.The proportion of open space is the largest,the proportion of other space types is basically the same.Activity type and the number of people in open space and half open space are significantly more than other space,making them the most popular types of spring plant landscape space.(3)Spring plant landscape type in Hangzhou Universities are various,in which the main tone of flowering plants and foliage plants are obvious.During the 46 quadrats,that are surveyed the number of both flowering and folioge plants community and flowering plants community is the most,they are the main ornamental plant community types in spring in Hangzhou campus.The average projection value in the quadrat of both flowering,foliage,fruit and bud plant landscape is the highest and has the best landscape effect among all the kinds of plants and scope,followed by both flowering and folioge plant landscape and flowering landscape.The average projection value of folioge plant landscape is the lowest and it's spring landscape effect slightly monotonous.Both flowering,foliage,fruit and bud plant landscape is worth mining construction in college campus landscape plant community types of plant configuration mode.(4)Using scenic beauty evaluation method,genetic accelerated algorithm combined with projection pursuit evaluation,the comprehensive evaluation model is set up to evaluate the 46 quality of spring plant landscape in of typical sample quality.Results showed that qevaluation indexs including the community stability spring,green rate of plants and ornamental characteristics richness have bigger influence on the Spring campus plant landscape quality,they are main factors that campus plant landscape and spring plant landscape construction should taken into consideration.
