Study On The Features Of Plant Landscape And Subtle Intervention Renewal Of Traditional Village In Western Fujian

Traditional village has experienced the changes of history,which reflects the wisdom of the harmonious coexistence of man and nature.As an indispensable component of traditional village landscape,the plant landscape is the soul of traditional village.To a certain extent,the composition of plant landscape establishes the keynote of traditional village style and ensures the vernacular of village localism.However,the increasingly prominent contradiction between urban and rural areas has led to the destruction of traditional village plant communities,and the original habitat is facing change and lack.It is urgent to understand and protect the traditional village plant landscape correctly,and it is urgent to explore the scientific protection theory and renewal method.In this paper,five traditional villages in Western Fujian were selected for field investigation,and the features of plant communities in different habitat types were analyzed and summarized.Based on the investigation and expert opinion,13 indexes are selected from four aspects of plant ecological environment,use attribute,visual aesthetic feeling and recreation experience.The evaluation system of traditional village plant landscape in Western Fujian is proposed.AHP-TOPSIS method is used to evaluate and weight the research objects,and GISnormalized vegetation index is used to analyze the landscape ecological situation of the village.The plant landscape features of the investigated objects were summarized from three aspects: courtyard forest,fengshui forest and waterside forest.Based on this,the paper summarizes the needs and key points of the renewal of the traditional village plant landscape in Western Fujian,carries out the subtle intervention renewal of the five traditional village plant landscape,puts forward the relevant measures and renewal mode,and provides reference and reference for the future research in this field.(1)Plant community features: There are 225 plant species,belonging to 122 families and 189 genera.The number of herbaceous plants ranks the first place,accounting for 38.67%,87 species in total,belonging to 38 families and 64 genera;trees take the second place,accounting for 35.56%;bamboo and aquatic plants are less,accounting for 2.67%.The community type is dominated by evergreen trees and herbs,and the dominant species are mostly local species,accounting for59.59%;shrubs and lianas are seldom used.Evergreen trees planted in fengshui forest and waterfront forest.Most of them are used in the community,accounting for 61.20% and 47% respectively.The garden plants are mainly herbaceous plants,accounting for 82.2%,followed by lianas.The species diversity of plant landscape community structure in front of the house and behind the house is relatively high,mainly in themulti-layer structure,the arbor shrub grass combination is harmonious,the plant species in the linear corridor plant community is relatively small,mainly in the tree species,the overall landscape line is obvious,and the level is prominent.(2)Evaluation system construction and landscape ecological analysis: AHP-TOPSIS method was used to complete the construction and weighted ordering of five traditional village landscape systems.The results show that the ecological environment weight is the first,the weight ratio is 0.606,the integration degree of plants and surrounding environment,ecological protection,seasonal changes and other factors are the first consideration,the weight ratio is the first in each criterion level;the CI value of plant landscape in Peitian village is 0.603,and the comprehensive quality of plant landscape is high.In the analysis of village landscape ecology,the vegetation coverage area of the research object is relatively ideal,the healthy areas of Zhangdi village and Peitian village account for 52.8% and 44.7%,and the high healthy areas of Chuxi village and Bizhou village account for 45.9% and 53.6%.(3)Combined with the comprehensive evaluation results and field investigation results of the traditional village landscape in Western Fujian,the traditional village plant landscape is renewal from the ecological level,the plant landscape level and the plant practical level;the paper puts forward the renewal strategies for the deficiencies in the construction ofthe village plant landscape,and recommends the trees,shrubs and grasses suitable for the use in the renewal of the village plant landscape,a total of75 species;and the plant community The structural model is further Renewal and several plant allocation models are proposed.Traditional village plant landscape is a dynamic process.It is not only necessary to solve the current problems in the development of plant landscape,but also to find and face the new problems.The purpose of this paper is to study and explore the features of plant landscape in traditional villages in Western Fujian,as well as the specific ways and methods of subtle intervention renewal,hoping that this achievement will have a certain reference for future research.
