Landscape Evaluation And Human Comfort Analysis Of Plant Community In Xinxiang People’s Park

Taking the garden plants in Xinxiang people’s Park as the research object,this paper evaluated the landscape of the garden plant community,and analyzed the environmental factors and human comfort of the community:(1)There are 176 species,60 families and 120 genera in Xinxiang people’s Park.Trees,shrubs and herbs were the most,accounting for 53.4%,21.6% and 15.9% of the total respectively;Vines and aquatic plants accounted for only 6.8% and 2.3% of the total.There are 22 evergreen trees and 72 deciduous trees in arbors and shrubs;There are 13 evergreen shrubs and 27 deciduous shrubs.The dominant families are Rosaceae,Oleaceae,Leguminosae,Cupressaceae,Aceraceae and Gramineae.There are 80 native plants and 96 exotic plants.In terms of ornamental characteristics,arbors accounted for45.4%,shrubs 31.8%,herbs and vines 11.4% respectively;In view plants,80% were arbors,16.7% were shrubs,and 3.3% were aquatic plants;Among the flowering plants,arbors accounted for 30%,shrubs31.7%,herbs 26.7%,vines 6.6% and aquatic 5%;Among the fruit plants,arbors accounted for 64.3%,shrubs 17.9%,herbs 7.1%,and vines 10.7%;Among the ornamental plants,arbors accounted for 85.7%and shrubs 14.3%.(2)SBE and AHP methods were used to evaluate the landscape of the garden plant community in Xinxiang people’s Park.The results showed that the highest SBE value was in plot 1 of arbor shrub grass garden plant community,and the average SBE value was 0.7497;The lowest SBE value was shrub and grass landscape plant community,with SBE value of-0.5331.The waterside and aquatic landscape plant community(Class V),arbor landscape plant community(class VI),arbor and shrub landscape plant community(class II)and arbor and grass landscape plant community(Class III)ranked second,third,fourth and fifth respectively.The results showed that the range of yahp value was 1.5926-3.2055.The highest average yahp value was arbor shrub grass landscape plant community(class I),and the lowest average yahp value was shrub grass landscape plant community(class II).The average yahp values of arbor shrub landscape plant community,waterfront and aquatic landscape plant community,arbor grass landscape plant community and arbor landscape plant community were 2 3.4,5.The results of the two evaluation methods were in the top 10 plant communities,I 1,I 4,II 2,II 3,III 1 and V 2.(3)Among all the six kinds of plant communities,arbor shrub grass garden plant community had the best effect in regulating temperature and humidity,followed by arbor shrub garden plant community and waterfront and aquatic garden plant community.(4)There is a certain correlation between the results of plant community landscape evaluation and human comfort analysis.The richer the species in the garden plant community,the higher the landscape evaluation value,and the more suitable the human comfort.
