| Since 2015,four central documents have been proposed to develop agri-tourism vigorously.Agri-tourism has become a major trend in the transformation of agriculture.The best allocation of agricultural resources can be achieved through the developing potential of agricultural resources in depth and adjusting the agricultural structure.Agritourism plays an important role in the strategy of rural revitalization,and it is the great potential industry in the development of agriculture.But behind the vigorous development of leisure agriculture,there are also a series of problems.For example,the lack of quantitative evaluation and analysis of resource factors makes the distribution of resources unreasonable;the spatial pattern of leisure agriculture is chaotic,resulting in waste of resources.The reasons are as following: the planning and designs of agri-tourism are mainly based on subjective experience;planning and analysis methods are not scientific and the planning means are not advanced.Therefore,the application of digital technology in the planning of agri-tourism is of great practical significance.It can provide scientific and reasonable technical support for the planning and design of agri-tourism.By reading the research of digital technology in agricultural planning at home and abroad,this paper selects the ShunPing Pangu manor as the research area based on the theory of digital planning,location and landscape ecology.We use the application of digital technology for planning and design.The main content and results are as follows:(1)By the unmanned aerial vehicle(UAV)low altitude remote sensing technology,the data of research area is collected.We can get the real-time data of DOM and DEM.The problem of the time difference caused by the traditional satellite remote sensing image and the image scanning image is solved.The situation of the topography,land use,vegetation cover,traffic and water conservancy in the study area is more accurately understood.We can find it laying a good foundation for analyzing.(2)According to the characteristics of agri-tourism in the study area and the principle of index selection,select nine evaluation factors to construct a agricultural suitability evaluation system.The nine factors include elevation,slope direction,slope,vegetation coverage,situation of land utilization,soil thickness,road accessibility,water resources and visibility.Weight the evaluation factors,and divide the tourism suitability of each evaluation factor into 5 grades.Through the weighted superposition function of GIS,the results of suitability evaluation of the whole agricultural tourism park were obtained,which were divided into highly suitable area,moderate suitable area,general suitable area,basic suitable area and unsuitable area.According to the evaluation results,the research area is divided into suitable space layout by means of digital analysis.The transformation from qualitative to quantitative is realized,which makes the planning scheme more scientific and reasonable.(3)The computer aided design technology is used for detailed planning;use AutoCAD software for plane planning and design;a three-dimensional space model is established by SU software;the plane drawing is processed with PS software,and then,the corresponding analysis chart is obtained.Finally,the rendering of the scene is displayed with the Lumion software.The achievement of planning achievement from plane to stereo,from static to dynamic is realized.Form realistic,immersive visual feelings. |
