Study On The Information Extraction And The Spatial Distribution Of Resident In Puge

Under the background of big data,using of multiple data sources remote sensing data,quickly and accurately extracting information of residential area,it is an important significance for town construction,urban planning,urben digitalize and GIS land use data updating.The residential information layout optimization study can improve the ecological environment,promote economic and social development,enhance land management ability,perfect land utilization efficiency and keep land sustainable ability.In this paper, the method of object-oriented can extact residential information to lay good foundation for residents’ synthesize development strength evaluation and optimize the residents’ layout.The main research results are as follows:(1)In the analysis of multiple data sources remote sensing data,the vegetation and non vegetation information can be distinguished by spectral analysis. Through the analysis of texture features,the information of farmland and non farm fields can be distinguished. By shape analysis,road and non road information can be distinguished.With object-oriented classification,the extraction model of threshold of spectral feature,shape feature and texture feature can extract residential area.(2)Through the study,we got to know that residents of the entire county in Puge County have a trend of aggregated distribution.In the topographic index interval(0~0.35),it is the dominant area of the residential area. Within the 500 m range of the river,residential area density is relatively high.(3)The residential comprehensive development strength of each evaluation factor is quantified and calculated weight.Then the county’s comprehensive strength score can be obtained by the method of weighted index summation.The entire county can be divided development of low strength,development of middle strength capacity and development of high strength.(4)By the study of residential optimization layout,the residential layout and township layout area ratio of development level of each strength can be known.The region should develop mode is the two axis,main and six points. The spindle for the county is the wood River Basin and the other axis is the West Luohe River Basin.A main township is the Pechiney town.Six points refers to the six towns,namely Luojishan Town,Luowu Village,Qiaowo Town,Jiatie Village,Huashan Village,Wudaoqing Village.
