A Study On The Application Of GIS Technology In The Planning Of Mountainous Scenic Area

With the the arrival of big data,construction of digital city and smart city.GIS as the information technology,more and more are well known and used by planners.It can effectively aim at the complexity and particularity of mountain scenic area,becomes an essential technical means for the planning of mountain scenic area.In order to improve the planning method of scenic area and increase the planning effect,this paper uses the GIS comprehensive analysis method to studies the application of GIS in the planning of mountain type scenic area from of theory and Practice two aspects.In theory aspect,this paper summarizes the existing problems of traditional planning methods in scenic area,and expounds the necessity and feasibility of applying GIS technology in scenic area.In the empirical aspect,Taking Chaoyang Lantau Peak scenic area as an example,introduces the application of GIS in the planning of mountain scenic area from three aspects of the preliminary investigation and research,the protection cultivation plan and the route selection design.First,in the preliminary investigation.First of all,GIS can collect,store and analyze the basic data,and can carry out macro analysis of the planning area location,terrain,vegetation conditions,hydrological conditions and so on.It also can provide reference for planning route personnel on-site reconnaissance,and be able to field exploration with GPS.The results show that the preliminary investigation and research with the help of GIS technology can greatly improve the efficiency and depth of research,and lay a solid foundation for the later stage of landscape planning.Second,protection and cultivation planning.The protection and cultivation plan is affected by the distribution of landscape resources,ecological sensitivity,land suitability and comprehensive value.Selection of human and natural landscape distribution to analysis the distribution of landscape resources.Ecological sensitivity was analyzed by five factors:elevation,slope,aspect,NDVI vegetation index and surface runoff.Land suitability was analyzed by six factors,such as topographic relief,ecological sensitivity,distance from protected water,distance from cultural relics,unit distance,distance from villages and towns,and land use.Three factors including cultural security pattern,ecological value and visual distance effect were selected to evaluate the comprehensive value.Comprehensive analysis results were conducted to protection and cultivation planning classify,classified protection and realize the 3D coordinate display of the protection zoning boundaries.The results show that the planning method of Conservation Cultivation Based on GIS can ffully consider the factors influencing the protection regionalization,define the protection boundaries,realize more reasonable protection of the scenic area and achieve the unity of protection and development.Third,the tour line selecting design.Selected elevation,slope,sight and visual sensitivity factor to establish the tour line cost based GIS data set,the computational cost of distance and direction,select tour line optimal path,and the traditional method of line selection results were analyzed.The results show that the diversity and accuracy of GIS method are better than those of traditional methods.The purpose of this study is through the application of multi-disciplinary integration to find out more scientific and rational planning methods.It can be used as a reference for the further research of scenic area planning theory and technology,and the application of GIS in scenic spot planning.
