Rural Settlement Space Pattern Based On 3S Technology And Influencing Factors

The rural settlement is a place where the local residents live,produce and live in a non-urban area.Its early formation and development after its formation are affected by a series of factors.Among the various influencing factors,natural and human.The impact of influencing factors on rural settlements is obvious.This paper takes Zhenyuan County of Guizhou Province as the research object.Through field research,the remote sensing image of the research area is remotely interpreted by using visual methods.After the field investigation,the sign of remote sensing interpretation is established and once again out of the field.The review is carried out to interpret the remote sensing image indoors,and the data of rural settlements and influencing factors are extracted according to the content of the interpretation.The spatial pattern of the research area(Zhenyuan County)and its influencing factors are studied,and the altitude is analyzed.Natural factors such as slope and water system,as well as the influence of economic and social factors such as social development,traffic roads,population structure and urban and rural planning on the spatial pattern of rural settlements.It provides reference for the optimization of rural settlements in Zhenyuan County of Guizhou Province and the development of urban and rural integration.The main contents of this paper are as follows:(1)A detailed introduction to domestic and foreign research on rural settlements and the frontier developments in rural settlements in recent years,and the significance of research in the context of rural revitalization.(2)It mainly introduces the geomorphology,climate hydrology,the status of land resources and the demographics of different structures in the socio-economic profile of the study area,the economic development of Zhenyuan County,and the second land use.In the case of land use in Zhenyuan County,a preliminary understanding of the basic situation of the study area(Zhenyuan County)was carried out,and a preliminary exploration was made on the development of the current rural settlement in the study area(Zhenyuan County).The data is to provide accurate data for the study,so accurate interpretation is needed to lay the foundation for the next interpretation.(3)Preparing for remote sensing interpretation,combining 3S technology to conduct field investigation,establishing interpretation marks and completing map interpretation,and obtaining the basic conditions and image features of remote sensing images.The images to be used are the resources independently developed by China.The remote sensing image taken by the surveying and mapping satellite(ZY3)is based on the previous pre-processing stage provided by the project.The clarity and precision of the image have met the needs of the research on rural settlements.For remote sensing images,only the geographic coordinate system needs to be redefined,and the data and images are geographically corrected and registered.After the target is clearly understood,the establishment of remote sensing interpretation marks is an important part of the field investigation work and specific operations.A step of.After preparing for the preliminary preparation,extracting and researching the land use profile information and natural attributes of the study area,using the visual interpretation to interpret the data and extracting the data of the rural settlement,the type of interpretation mark established by the field investigation is The main reference,followed by field field verification to verify the accuracy of the interpretation data and modify according to the results of the interpretation,so that the data can meet the needs of rural settlement research,and finally obtain a classification map of land use types.Through the information data of the geospatial data cloud,combined with the vector boundary map of the study area and using the ArcGIS 10.2 mask tool to extract the DEM data needed for the research,generate an altitude classification map,and then generate a slope classification map by calculation.On this basis,according to the land use type classification map,elevation grade map and slope grade map generated by remote sensing interpretation,the rural construction land data in the land use type data is extracted,and the spatial analysis function of ArcGIS is used for superposition analysis to study Zhenyuan The county’s rural settlement spatial pattern and the research area of the influencing factors laid the foundation for data and theory.(4)Through the pre-processing of data,using ArcGIS 10.2 to process the data,analyze the spatial pattern characteristics of rural residential areas in the study area(Zhenyuan County),and analyze the spatial distribution characteristics,scale characteristics and discrete characteristics of rural settlements.Scale characteristics,spatial distribution characteristics and discrete features of settlements.From the basic scale characteristics,there are 4552 plaques in Zhenyuan County in 2018,with a total area of 2971.6hm~2,accounting for 1.6%of the county’s total area,with an average plaque area of 0.65hm~2 and a maximum of 18.7hm~2,which is less than the average.A total of 3166,accounting for 69.6%,1386 than the average,accounting for 30.4%,so we can know that the number of rural settlements in Zhenyuan County is large,small-scale rural settlements exist as the main form,and the number of large-scale rural settlements is small;From the perspective of spatial distribution characteristics,there are great differences in the distribution patterns of rural settlements in different areas of Zhenyuan County.The estimated spatial density of rural settlements generally shows a downward trend from northwest to southeast.The total number of rural settlements in Zhenyuan County is "intensive in the northeast and sparse in the southwest".The distribution of the valleys of the two large rivers is concentrated,with a large number and high density.From the perspective of discrete characteristics,the rural settlements in Zhenyuan County are presented in the spatial distribution.Significant spatial agglomeration features.(5)Based on the analysis of remote sensing image data and access data,according to the regional nature of Zhenyuan County,spatial superposition analysis,nuclear density analysis and multi-ring buffer analysis methods are used from two aspects:natural condition factors and socio-economic impacts.Investigating the influencing factors of elevation,slope,water system,social development,traffic road,population structure and urban and rural planning,and analyzing the impact of various influencing factors on the spatial pattern of rural settlements,quantitative analysis of natural conditions Factors such as elevation,slope,water system factors and traffic factors in socioeconomic factors.
