Landscape Evaluation And Functional Analysis Of Linear Green Space

With the continuous development of social economy,the urban population concentration and the change of people's living leisure,urban green space cannot satisfy the needs of urban daily recreation,large park green space is often crowded of people,more and more people in the city's linear green space as choice because of its convenient,thus effectively disperse the bearing capacity of the large parks.Urban belt park is an important part of urban green space system,has the certain length and width,as well as the linear green vegetation coverage.It has a good connectivity and extensibility,able to connect to a variety of green space types,crosses,extends to the city streets,in every corner,make urban residents enjoy nearby green public space,it is a kind of multi-scale economical compound green.In this paper,based on the green landscape belt function evaluation,so as to further perfect its functions and better for the future excavation and exert its benefits to provide the reference.This article first reviewed from the research of landscape evaluation at home and abroad,using the analytic hierarchy process(AHP)and fuzzy mathematics method,from the ecological benefit,social function,visual effect three aspects: the selected evaluation criterion to establish urban zonal greenbelt landscape function evaluation model system,and combining the field survey and the interview way using statistical method by Excel tool for information to the public of the collected data were analyzed.It is concluded that the shortage of the ribbon on the function of green space and the optimization strategy of specific research conclusion is as follows:(1)Using software yaahp,the comprehensive function through software can objective and convenient to obtain the weight of index factor,combined with expert judgment and the function of group decision making,effectively reduce the artificial calculation error of the past.Evaluation criteria,the ecological factors accounted for64.7%,green function in the ecological function of the main,followed by the social function and visual effect.In evaluating factor layer,green crown density,plant diversity,stay,green quantity,accessibility etc factor weight is higher,combined,more than 50%,these factors are also green ecological and social service value of another form.(2)The linear green space usage of questionnaire and interview results show that the zonal greenbelt service radius are mainly composed of nearby residents,into the green space of convenience is the main choice of their work;On the green land use purpose is given priority to with sports fitness,leisure,recreation,dating,chatting,walking,communication space and other activities is the main content,points out that is very popular in zonal greenbelt role is different from other green space forms an important aspect.Population results in the activity,is a major consumer of green land in the elderly,is coming to the age group with highest frequency of the green space.In the interview,the needs and requirements of the urban residents of recreation space space is large,reflecting the lack of a objective of urban green space.(3)The evaluation results show that: the linear green space of Wenlao road use efficiency is higher,which D section(Cultural park)part of the highest value as a whole,of which the east riverside green space and water landscape is the best,in central square in the west of the vegetation coverage is less,the square area is too large,comfort level is low;Section C of catalpa park(Xuezi park),one of the central and western landscape quality is poor,poor east,south and henan institute of finance and economics into the campus green space;Section B(Huiyin square)the overall landscape quality in general,the poor quality of the local landscape,needs further reform to improve;A period of only trees and green fence,by dismantling the side of the road or building back illegal buildings,increase the width of green space,enrich the plant community structure.Each function of green space still has room to improve.Finally,through the analysis of comprehensive evaluation and the research results obtained,linear green space need to improve and perfect the following aspects:the internal space of the optimization of green space and improve the form beauty;Pay attention to cultural connotation of injection and implant;Pay attention to the service function,people-oriented;Strengthen the management level of green space,fully tap the green land in all kinds of benefits,and provide the reference and guidance for future urban construction.
