Study On Ecological Sensitivity Evaluation Of Paoling Mountain Park In Shanghang County Based On GIS

Mountain Park is an important part of urban green space,and it has important significance in the construction of ecological civilization.According to its concept,Mountain Parks have multiple attributes of"Ecological Restoration,Function Satisfaction and Culture Transmission”at the same time,so as to coordinate the balance between the development,construction and protection of Mountain Parks and realize the optimization of economic,ecological and social benefits,which is the key to the sustainable development of mountain resources.This study in Shanghang County Paoling Mountain Park as the research object,from the perspective of ecological sensitivity evaluation research,closely related with many factors,evaluation methods,trying to build evaluation index system of Mountain Park,it is concluded that the ecological sensitivity analysis,functional area according to the results,and puts forward corresponding Suggestions,provides the countermeasures for the park’s planning and design,to realize the sustainable development of urban ecological civilization.The centents are as follows:(1)This study systematically summarizes and analyzes the development of Mountain Park at home and abroad,the related concepts and theories,and research related theory and practice of ecological sensitivity,contrast evaluation objects,dimensions,selecting the factors,evaluation methods of similarities and differences,and expounds the sensitivity of the advantage of GIS technology in Mountain Park,determine to GIS Weighted Superposition method and Analytic Hierarchy Process(AHP)to give priority to the Ecological Sensitivity Evaluation Method.(2)Based on the ecological sensitivity analysis of factors affecting of Mountain Park,the selection rule of the five layer factor:the topography,natural conditions,vegetation conditions,human activities,landscape resources,and 12 indicators layer factor:elevation,gradient,slope direction,soil type,water,buffer,air negative oxygen ion concentration,vegetation types,canopy density,biomass accumulation,road buffer,the types of land use.,landscape resource level to establish Ecological Sensitivity Evaluation Index System of Mountain Park,and established the weighting factor.(3)Paoling Mountain Park in Shanghang county for practical cases,the data collection and field investigation,to deal with the collected data to establish the GIS database,ecological sensitivity factor is evaluated,the single factor sensitivity classification figure 12 index layers,and through the Analytic Hierarchy Process(AHP)to determine the weights of evaluation factor,then used GIS weighted superposition method of weighted superposition comprehensive ecological sensitivity analysis are obtained.(4)Based on the ecological sensitivity evaluation results,in combination with the practical situation of Paoling Mountain Park and the need of planning and construction,the park ecological function zoning,established the ecological conservation areas,ecological buffer,the development of these areas(landscape construction I,landscape construction II),the data of area are 107.41hm2、262.35hm2、91.79hm2(landscape construction I area 31.81hm2,landscape construction area Ⅱ 58.98hm2),The percentage of the total area of the park is 23.32%、56.96%、19.72%(6.91%for landscape construction area I and 12.81%for landscape construction area Ⅱ),and put forward the corresponding countermeasures and suggestions.The research results will provide scientific basis for the planning and design of Paoling Mountain Park in Shanghang County and realize the sustainable development of urban ecological civilization.
