Study On Landscape Planning Of Eco-Sightseeing Agricultural Garden Based On GIS Analysis

With the arrival of economic development,the material living standard of human beings is constantly improving.Various urban problems also produces immediately: traffic congestion,environmental pollution,the imbalanced urban-rural development,the increase of survival pressure and more and more urban residents all long to return to nature.At the same time,it’s difficult to support the operation of the economic development of towns and villages around the city by only depending on traditional agricultural production.The sustainable development of agriculture is at stake.The state has begun to focus on the issue of the sustainable development of agriculture and developed many guiding documents,in which its development direction in the future is also planned.Based on the above,the ecosightseeing agricultural garden which is based on sightseeing,recreation,production,popularization of science and experiences has quickly received widespread favor.The ecosightseeing agriculture garden has beautiful natural scenery and lively local atmosphere.There is a huge tourist market and development space,which can not only satisfy the longings of urban residents for a better living environment,but also can be used as an agricultural management mode under the new situations.With the rise of the ecological touring-agriculture garden,there is no unified conclusion on its concept to this day,which also causes many problems including inaccurate positioning,lack of creativity and weak sustainable development in latter part and so on.To sum up,before planning the sightseeing park,we should collect a lot of information about the site and make a scientific,objective and reasonable analysis of it.However,most of the existing eco-sightseeing agriculture gardens are planned under the guidance of the idea of human subjectivity.Some of them are confused with other scenic spots and parks,and most of them lack the utilization of the existing resources of the sites.They are developed under the slogan of ecology without the premise of "ecological protection",only focusing on pursuing interest.In order to solve the above problems,this paper introduces the geographic information system(GIS)to carry out the preliminary ecological assessment of the sightseeing garden.Based on the GIS technology,the complex topography of the planning site and the status quo of ecology landscape of the siteare analyzed,which is a necessary prerequisite for the planning of the eco-sightseeing agriculture gardens,and provides a scientific basis for the ecological protection and rational development and utilization of the garden in the late period.In this paper,the landscape planning of eco-sightseeing agriculture gardens based on GIS analysis is studied as follows:(1)This paper introduces eco-sightseeing agriculture gardens and the research background,the objective and significance,the content and method of and its development at home and abroad.At the same time,it introduces the concept and design concept of ecosightseeing agriculture gardens in detail,and sums up the existing problems of sightseeing parks in China.According to the analysis of a series of problems,it can be concluded that the application of GIS technology in ecological suitability assessment can be used for providing a scientific basis for its development and construction.(2)This paper takes eco-sightseeing agriculture gardens as the main research object,and Danjiangkou Haoping eco-sightseeing agriculture garden as the design practice.Through the methods of field investigation,data collection,information data collection and literature review,the basic information and related data of the study area are obtained.According to the systematic analysis of the planned land,seven factors are selected:elevation,slope,slope direction,road,river,lake and building.Delphi method and analytic hierarchy process(AHP)are used to define the above factors in the factor layer of analysis of ecological suitability assessment.And the index of the factor layer is marked in pairs through their comparisons.The values of 9,7,5,3 and 1 represent the most suitable,high suitable,medium suitable,low suitable and unsuitable grade values respectively.The intermediate values of 2,4,6 and 8 are the transition values of the appropriateness.The scoring results are classified to conclude the judgment matrix,and determine the weight of each index value.The analysis diagram of suitability assessment grades is made by a single influence factor in stages.Finally,arcGIS is applied to vector superimposition of index factors,and a new data layer is obtained.After overlaying raster,a general grade analysis diagram that is a comprehensive evaluation map is obtained to analyze the suitability of the planned area.Through the analysis of the comprehensive evaluation map,the landscape ecological function zoning map was made and analyzed to guide the later planning of agricultural sightseeing garden.(3)Based on the summary of the comprehensive situation of the site and the results of ecological suitability assessment,the planning strategies of Haoping Eco-Sightseeing Agricultural Garden in Danjiangkou are determined,including the design objectives,design principles and planning methods.Finally,the overall layout,the distribution of functional zones,traffic system planning,plant landscape design and ecological environmental protection are determined.Various feasible suggestions were put forwardfor the planning scheme of Haoping Eco-Sightseeing Agricultural Garden in Danjiangkou.Hope that through this study can introduce the ecological suitability assessment of GIS into the planning of agricultural sightseeing parks,providing a feasible basis for later planning.Based on the ecological suitability assessment and analysis of the planned area,this paper puts forward the rational use of land in the planning of eco-agricultural sightseeing park,so as to achieve the goal of planning and construction,such as maintaining the ecological environment of the site,giving full play to the geographical advantages of the site,avoiding large-scale excavation and filling,and achieving the goal of sustainable development of the park.
