Based On Ecological Suitability Analysis Of Sanya Tropical Plants Expo Park Planning Study

With the advancement of urbanization in China,more and more mountains have been developed and become to the urban mountain parks which are the emerging leisure place of life.The urban mountain park is not only an organic part of regional ecological base,is also a very important part of driving the development of regional tourism economy.In recently,the planning of urban mountain park is traditional planning concept of subjective.Many scholars study qualitatively mountain park planning and design.However,there are little urban mountain park planning which is objective,scientific and targeted.And on the ecological protection into consideration is not comprehensive.Ecological suitability analysis as a relatively scientific and intuitive analysis method is based on the GIS technology which is a technology platform to deal with complex and multidimensional information.Ecological suitability analysis is to consider more factors based on integrated suitability and ecological sensitivity and it is the scientific basis for ecological planning of urban mountain park.This paper is based on the land evaluation theory,landscape ecology theory and sustainable development theory using GIS spatial analysis and superposition technology for the research of urban mountain parks’ ecological suitability analysis.Meanwhile the Sanya tropical plants expo park is as the object of case study to analysis its ecological suitability and based on the results to guide the related planning such as the space layout,the organization of functional zoning,road planning,scenic spot layout,supporting facilities construction planning,plant landscape planning and ecological environmental protection planning.The results of the study are as follows:(1)It comprehensively and systematically analyzes and summarizes the ecological suitability analysis of the origin,development,application field and ecological suitability assessment method at home and abroad.It elaborates the present situation of the urban mountain parks’ planning research.It emphasizes the importance and necessity of planning and constructing the urban mountain park based on ecological suitability analysis.(2)Through the study on the basic theory of GIS technology and the related research in the field of application,based on the functions and features of the GIS platform,data and spatial analysis,the ecological suitability analysis method of the urban mountain park is studied.(3)This paper regards Sanya tropical plants expo park as the object of case study and selects 12 ecological suitability evaluation factors besides slope,aspect,degree of relief,ecological sensitivity,vegetation types and land use type,the density of road buffer,the scenery resources and vision.Then it gets 9 indexes of single factor maps and single factor suitability classification figure.And analytic hierarchy process(AHP)is used to determine the factor weights were 0.0727,0.0781,0.0852,0.1822,0.1767,0.0795,0.0507,0.1415,0.1334.Next it applies Arcgis 10.2 weighted superposition of 9 indicators and gets Sanya tropical plants expo park’s ecological suitability value of 1.433 to 1.433.According to the interval value study area is divided into a most suitable area,suitable area,basic suitable area,not suitable areas and badly suitable area,the area are 33.56hm2,82.11hm2,132.14hm2,195.29hm2,143.16hm2 and 586.33hm2 what percentage of the total area of the study area are 5.72%,14.00%,22.54%,14.00%and 22.54%.(4)It is based on ecological suitability analysis of Sanya tropical plants expo park and regards the result of ecological suitability analysis as the basis of quantitative guidance planning.According to the requirement of the master planning,the target and principles of planning and other relevant planning,combining qualitative analysis and quantitative analysis,it do some planning researches of Sanya tropical plants expo park such as the space layout,the organization of functional zoning,road planning,scenic spot layout,supporting facilities construction planning,plant landscape planning and ecological environmental protection planning.To sum up,with the deepening of the landscape ecological evaluation and planning research,and GIS technology being popular in landscape planning,many considerable progress have been made.Applying GIS for ecological suitability analysis in urban mountain park is needed.It is a kind of inevitable development trend to regard the ecological suitability analysis as the guidance of urban mountain parks’ planning and construction.And it is more scientific,objective and reasonable.
