An Analysis Of The Landscape Construction Of Rural Settlements In The Main Urban Area Of Chongqing

Requirement,this paper takes chongqing beautiful livable construction of chongqing’s emphasis on rural sides greening in recent years,and now the problem of rural development is more outstanding in the background through rural settlement landscape plant related disciplines theory combing conception,summarize and country plant landscape dynamic research at home and abroad,selected 12 typical villages in chongqing urban area as the main research object,the rural settlement within the plant landscape of field investigation,the settlement road green space is divided into public leisure garden green land waterfront green space four green space for plant growth and species composition of ornamental characteristics application frequency power plant configuration mode Demand analysis and other aspects of the analysis using AHP analytic hierarchy process to select and evaluate the existing plants,select trees suitable for the greening of rural settlements in Chongqing,and put forward various green plant configuration models,provide certain strategies and methods and reference for the current construction of rural settlement plant landscape,the research results are as follows:(1)There are 229 species of plants in 206 genera and 100 families in 12 typical rural settlements.According to the analysis of various types of green space,the garden green space has the largest number of plant species,152.The second is the public leisure green space,the waterfront green space has the least plant species.According to the analysis of different types,there are more species of hill-base type and riparian type rural settlements,and the least species of hill-top type rural settlements.From the point of view of plant life type,the most existing herbaceous plants,followed by trees,lianas least.From the analysis of ornamental characteristics,there are 83 species of plants whose main value is flower observation,which can be divided into white,pink,red and so on.There are a total of 38 species of ornamental plants.From the plant application frequency and important value,osmanthus,camphor,yellow kudzu,citrus and other plants of higher important value.From the analysis of plant growth potential,the garden green space plant growth potential is the best,the waterfront green space plant growth potential is the worst.In the form of configuration,trees selected for various green plants are mainly fruit trees and common ornamental trees in rural areas,while shrubs and herbs are mostly commonly used in landscaping.The plant configuration forms of courtyard and public leisure green space are mostly multi-layer structure,with abundant plant community and single road and waterfront plant configuration forms.(2)By issuing questionnaires to villagers and tourists,it is found that respondents have a high satisfaction with the current rural plant landscape and generally support the construction of plant landscape;The respondents had different plant selection tendencies in different Spaces.The courtyards were mainly planted with fruit trees and vegetables,while the public space,road space and waterfront space were all tended to be dominated by trees and flowers and shrubs.Compared with the urban landscape,the villagers want to keep the local style and try their best to meet the functional needs.The respondents generally think that the problems existing in the current settlement greening are the single plant configuration and the lack of landscape features.(3)The AHP comprehensive evaluation model was used to select and evaluate the existing plants,and the ranking of factor weight in the criterion layer was as follows:growth characteristics > economic benefits > ecological benefits > ornamental characteristics > cultural connotation;There are 18 indicator layers under the criterion layer.The evaluation method focuses on fuzzy grade evaluation,quantitative evaluation and accurate description.Excellent tree species were selected according to the evaluation results.It involved 25 kinds of backbone trees,25 kinds of keynote trees,16 kinds of backbone shrubs,16 kinds of keynote shrubs,24 kinds of backbone groundcover,24 kinds of keynote groundcover and 5 kinds of backbone vines.Such as osmanthus,citrus,grapefruit,hu zhi,wax plum and other outstanding tree species.(4)The principle is the combination of protection and reconstruction,the combination of ecology and economy,the satisfaction of public needs and humanistic feelings,and the emphasis on practical functions.Three different plant allocation strategies of ornamental,mixed and economic types were proposed in the garden.The public leisure space is divided into fitness space,small amusement park and entertainment communication space.Roads are divided into main roads,secondary roads and branches.River system puts forward the configuration form of river course,canal,pond.Different optimization strategies and plant allocation patterns were proposed according to different types of green space.Taking longquan village phase I as an example,combining the results of plant investigation and species evaluation,this paper applies it to the case reconstruction,providing reference for the practice of rural construction in the main urban area of chongqing in the future.
