Research On The Characteristics Of Bryophyte Community And Its Landscape Evaluation In Guiyang Forest Park

Bryophyte is a kind of higher plants with ornamental value,second only to angiosperms in species number.A good bryophyte community can make the park green space better play its function of improving and beautifying the environment.However,there are few systematic studies on the bryophyte landscape in parks.In this paper,based on the theory of ecology,landscape aesthetics,plant community,deer rushed off to guiyang forest park,long Po Ling forest park,climb of yunshan forest park is made up of 138 species of moss plant community landscape composition,quantity,the life,diversity characteristics of system analysis,moss plant community on the basis of the investigation at the same time,using the corresponding analysis model,the research analysis the environmental factors that affects the moss species;Finally,AHP was used to systematically evaluate and analyze the selected 65 sample plots and put forward reasonable suggestions,and the dominant species of mosses were used for landscape construction.The results are as follows:(1)In 138 bryophyte communities in Guiyang Forest Park,there were 89 species of bryophytes belonging to 45 genera and 25 families,including 80 species of mosses belonging to36 genera and 20 families,and 9 species of liverworts belonging to 6 genera and 5 families.The moss resources in the forest park were relatively rich.There were 57 species of bryophytes belonging to 26 genera and 16 families in the sample plot of Luchongguan Forest Park,the largest number of species.There are 48 species of bryophytes belonging to 31 genera and 11 families in the sample plot of Denggaoyunshan Forest Park,and the number of species is second.There are39 species of bryophytes belonging to 16 genera and 11 families in Changpoling National Forest Common Sample,but the number of species is relatively low.(2)There are four families of bryophytes in the forest park,which are Peniclosaceae,Plusmosaceae,Pterymosaceae,Sericlosaceae,and the larger families are the most of the bryophytes.The dominant species are moscotrichum narrow leaf,moscotrichum fine leaf,moscotrichum polyclade,moscotrichum long stem and moscotrichum eutrichum.The bryophyte community types can be divided into six life types: cluster type,interweave type,fan type,tile type,tree type and pad type.In the park,the bryophyte community types of interweave type and cluster type are the most and the tree type bryophyte species are the least.(3)The species richness index and diversity in Luchongguan Forest Park were the highest,followed by Chang Po Ling Forest Park,and the lowest in Denggaoyunshan Forest Park.The mean values of Margalef richness index and Shannon-Wiener index were 0.55,0.4,0.38,and 1.07,0.94,and 0.89,respectively.Changpoling Forest Park had the highest evenness index and the lowest dominance index,with the mean Pielou index and Simpson index of 0.86 and 0.41 respectively.Denggaoyunshan Forest Park had the highest dominance index and the second highest evenness index,with an average of 0.48 Simpson index and 0.80 Pielou index.(4)23 species of important value of dominant species of bryophytes,with each sample to CCA sort of environmental factors,concluded that the major environmental factors that affect the moss distribution in forest park is light intensity,soil temperature,soil humidity,altitude,followed by Joe crown density,human disturbance degree,the growth substrate,the environmental factors that affects the small coverage is fading.(5)The landscape of bryophyte community in Guiyang Forest Park was constructed by AHP analysis method.Three criterion layers and 12 index layers were obtained,and the weight of each index was calculated based on AHP method.In the index weight of the criterion layer,ecological benefit accounted for the highest weight(0.7514),followed by landscape effect(0.1782),and service function(0.0704).In the index weight of factor layer,the growth condition of bryophyte is the most important,followed by the purity of plant community,and the scale agreeability and artistic conception beauty are the lower.In the index layer of landscape effect,the ranking of the weight value from high to low was the green visual rate > plant form > and overall environmental harmony > bryophyte level richness > artistic beauty;In the index layer of service function,comfort is the highest weight,followed by durability and scale agreeableness.In the ecological benefit,the weight of each factor is balanced,and the weight of bryophyte growth is the largest.(6)The 65 bryophyte community landscape samples in Guiyang Forest Park were comprehensively evaluated.The results showed that there were 7 bryophyte landscape samples of? level,accounting for 11% of the total.There were 20 bryophyte landscape plots of ? level,accounting for 31% of the total evaluation plots.There were 30 bryophyte landscape plots of ?level,accounting for 46% of the total.There were 8 ? bryophyte landscape samples,accounting for 12% of the total number of the evaluated samples.Generally speaking,the quality of the bryophyte landscape in Guiyang Forest Park was good.Through the sample analysis of moss flora,at all levels found mainly depends on the growth of moss plant community landscape quality,purity,and species diversity of health,and in size 12 indexes of integrated weight value ordinal ranking in the first three,it also suggests that the bigger influence on the moss plant community landscape quality,purity,growing health directly affect the visual effect,directly affect the desire of people enter the stop watch,species diversity,to a certain extent determines the level of aesthetic feeling.(7)According to the types and structure characteristics of bryophyte community in Guiyang Forest Park,the application mode of bryophyte in garden was put forward.Stone bryophyte made bryophyte sculpture and micro-landscape.Treophytic bryophytes for three-dimensional greening;Native moss community forms dry landscape moss landscape.
