Research On Spatial Distribution Pattern And Change Of Wuhan Employment

With the development of productivity and the progress of science and technology, the city’s modernization constantly to further promote, the type and scope of urban social and economic activities also expanded. The urban space structure which is the spatial carrier of urban social and economic development, in order to adapt to the new development situation, is constantly changing.Wuhan is the central city of national and is important to support the development of central China. Researching the employment spatial structure of Wuhan, learning the employment population spatial distribution form, summarizing the characteristics of urban spatial structure of Wuhan city at present, and discussing the the evolution of employment population spatial pattern in Wuhan city from1982to2010in order to look for the evolution and evolution mechanism of urban spatial structure of Wuhan city, is necessary for the urban planning and development of Wuhan city.As to research methods, based on sorting and summary the data, ArcGIS software displays the location quotient of employment and employment density. It adopts the isoline method combining with spatial autocorrelation analysis tools to identifies the determination of job centers and predicts the trend the linear regression in statistical trend prediction. While we analyze the evolution of the spatial form of employment by means of mean center and standard deviation ellipse in ArcGIS software. We use various statistical analysis methods and tools to show the employment space distribution pattern of Wuhan city as totally and accurately as possible.In this paper, the conclusions as following:(1) Wuhan have a large employment population and the employment structure is reasonable increasingly. Tertiary industry employment population continues to grow, the space form of employment present a pattern of single center, different regions have different employment structures and employment density gradients. The employment center of Wuhan between the Yangtze river and hanjiang river, employment density decreases gradually from center to the surrounding regions.(2)Different industries have different employment spatial distribution patterns. Manufacturing employment appeared a trend to outer suburb sand the third industry employment population is mainly concentrating in the central city, which is closely related to the urban development and the industry characteristics.(3)The evolution of employment space distribution pattern, based on cluster development of the center and appears to edge-axial of the center at the same time.Innovation of this paper lies in:(1) Identifying the urban employment center under the background of Wuhan which is constituted of three towns:with the methods of employment density contour, spatial autocorrelation, linear regression, mean center and standard deviation ellipse in ArcGIS software.(2)Analyzing the evolution of different spatial pattern between1982and2010, it is validity and authenticity because of the larger time span and the credibility of research data.
