Application Of ARCGIS In Rural Landscape Planning And Design

Since ancient times,rural landscape has been the key carrier of Chinese landscape culture and art.However,in the current of economic development in the era of reform and opening up,culture and aesthetics gradually decline and break off in the vast rural land.In recent years,with the proposal of the strategy of "rural revitalization",the construction of beautiful countryside has brought a rare opportunity for the planning and construction of rural landscape and the improvement of rural ecological environment under the full implementation of the government.Under this background,this paper systematically summarizes the concept,theory and planning principles of rural landscape planning and design,through the analysis of the present situation of the development of rural landscape planning and design,it is concluded that there are some problems in rural landscape planning and design,such as lack of research methods,lack of science,neglect of natural ecological environment,local culture and management,etc.The construction of rural landscape urgently needs the support of science and technology and the guidance of more perfect planning methods.In view of the above problems,the introduction of geographic information system technology,its excellent spatial analysis function is applied to the landscape planning of Tanwan Village,scientific and comprehensive technical analysis as the basis for decisionmaking.First of all,through the study of the technical functions of ARCGIS,this paper summarizes the advantages and application of ARCGIS in rural landscape planning and design.The quantitative analysis function and three-dimensional visualization analysis function of ARCGIS software are used to analyze the topography and land use status of the research base,including elevation,slope aspect,slope and other terrain elements analysis,landscape vision analysis and three-dimensional visualization model presentation.It accurately and comprehensively expresses the actual situation of the site,and the analysis results improve the stability and objectivity of the early analysis of landscape planning.Secondly,combined with the analytic hierarchy process,the ecological suitability analysis and evaluation system suitable for rural landscape planning is constructed.According to the on-the-spot survey and investigation of Tanwan Village,the planning objectives and principles are put forward.Under the guidance of dominant principle,restrictive principle,stability principle,systematic principle and maneuverability principle,elevation,slope aspect,slope,architecture,river,pond and road are selected as evaluation factors for ecological suitability evaluation.Under the guidance of the overall planning objectives and principles,the functional zoning planning of the planning area is carried out,and some planning suggestions are put forward for the construction land planning,road traffic planning and plant landscape planning of Tanwan Village.The results of topographic analysis and ecological suitability analysis by using ARCGIS software are more scientific,accurate,less workload and strong maneuverability,giving full play to the advantages of the site on the premise of maintaining the balance of the site ecological environment,and making a great contribution to the sustainable development of the rural landscape.Summarize the whole article.The problems and shortcomings in the research process are discussed,and the development prospect of applied research in this field is prospected.
