Layout Study And Application Of Rural Residential At Pan-Chaohu Lake Basin Based On GIS

Pan Chaohu Lake Basin is facing many economic,social and environmental issues,especially the development of the imbalance between urban and rural regional economic development,living standards and infrastructure is relatively backward.In this paper,the layout of rural residential category type research as a starting point,the main objective was to analyze the pan in Chaohu Lake Watershed land use on the basis of the status quo of rural residential area classification type of layout to study and calculate the correlation factors derived Evaluation score.Finally,rural residential layout corresponding optimization suggestions according to the special environmental conditions in the region's counties and districts in hopes of providing some advice for consolidation planning rural residential area of the layout,in order to better promote the coordinated development of urban and rural areas.Firstly,the ArcGIS platform,based on the spatial data engine,integration of geospatial data and attribute data to establish a basis for spatial database.On the basis of the database based on the use of common land use to analyze the neighborhood,such as diversification analysis,centralized method of analysis and a combination of the type of analysis to analyze the status of land use background areas;in this context,such as the use of neighborhood analysis,buffer analysis,vector analysis and spatial analysis methods superimposed grid overlay analysis,the layout of rural residential area classifying the type studied by calculating the impact of the comprehensive score factor based on the corresponding composite score and the score the range of near zone type division,identified by type of urbanization,urban joint type,developmental,developmental and migration restrictions with type five kinds of comprehensive layout type.Finally,build the system demonstration platform based on ArcGIS API for JavaScript.In summary,this paper work are the following aspects:1.The establishment of a space base on ArcSDE database.First introduced the study area and data the data sources,and then introduce the Spatial Database Library Technology,on the basis of the structure of the database infrastructure design,and finally the establishment of spatial database infrastructure.2.The use of spatial analysis methods to carry out research on rural settlements in space layout category type.Describes the entire watershed land utilization status background,in this context,mentioned some of the commonly used methods of spatial analysis and analysis model was constructed based on ArcGIS modeling tools,the final layout of various factors affecting rural settlements were spatial analysis,comprehensive scores of settlements to classify and give some development proposals.3.Based on the WebGIS ArcGIS API for JavaScript technology,design and realization of the presentation system.In a simple analysis based on demand,we introduce WebGIS technology,design and main function modules of the system architecture,the final realization of these functional blocks.In this paper,more quantitative analysis rather than qualitative analysis of the results of such analysis is more persuasive,using information technology tools to demonstrate geographic and attribute data,more intuitive and clear.By analyzing the basin of rural residential layout classification types,the urban system planning area,planning and rural residential finishing has certain research value and practical significance.
