成都市建成区形态动态演变及驱动机制研究
Study on Dynamic Evolution and Driving Mechanism of Built-up Area in Chengdu
摘要
Abstract
Urban morphology reflects the structure of urban functions,and it is important io study on urban morphological evolution. Four remote sensing image of 1978,1988,1997 and 2009 were collected .and the boundary of central city and adjacent suburbs of chengdu was intcrpreled, then long axis,short axis,perimeter,arcu,elongation,shape ratio and compactness were calculated from the boundary. The results showed that during 197R -2009, the average annual growth of urban areas was 7.49% ;the main direction of long axis was the northeast-southwest,and the main direction of short axis was west-east; urban renter moved around ihe Tianfu Square,and shift gradually towards the southwest; urban elongation changed first decreased and then inereaped,shape ratio changed first increased and then decreased,compactness increased continuously,and the urban developed from quantitative to qualitative. Urban morphology was influenced by natural,political,economic and cultural factors,the morphology shifts from round expansion to point-axis expansion,and center city district and surrounding counties achieved a spatial integration.关键词
