Residence Spatial Expansion And Its Human Settlement Environment Problems Of Dalian

The urban residential space is basic spatial type of urban society and important function space. With the development of the metropolitan suburbanization, the Expansion of Residential Space receives more and more scholar's attention. Since the reform, with the rapid development of Dalian's economy, the city size expands; the urban space form develops gradually into the polycentric group structure, land use structure is also adjustment and optimization along with it, the step of urban space expansion speeds up, the phenomenon of the housing suburbanization is obvious. Along with the further advancement of Dalian urban construction and the implementation of strategic that expansion towards the West and North, it will certainly cause the space and time evolution of residential land in new turn. The article summarizes and measures the housing space expansion of Dalian, and on the base of this has discussed the factors and the function mechanism that influence the housing space expansion, the housing plot construction, finally proposes coordinate direction and the countermeasure.For the core of urban space expansion measurement, the article carries on research from macroscopic and the microscopic two stratification planes. Firstly, attempting to use fractal theory math methods, this article studies on the distribution of residential land to quantitative portrays the evolved characteristic of residential area from time and the spatial angel since the 80's of the 20th century, and discuss the basic laws of residential spatial expansion. Next, along with the reform of the urban housing system deepening gradually and the vigorous development of real estate, the spatial-temporal complexity of housing plot is prominent day by day, and Residents' concept for housing and housing location in Dalian has unceasingly changed. Therefore, in the foundation of the macroscopic housing space, based on the existing statistical data and combined with the correlation data of housing plot during 1998 to 2006, which have collected by on-the-spot investigation and telephone inquires, utilizes the GIS formidable space analysis function, further promulgates the chronicle and spatial development order and distribution characteristics of housing plot for ten years from the microscopic stratification plane. The result indicated the phase characteristics of the housing plot's construction. In the spatial structure, housing plot spread along the old urban to the fringe area with the circle level shape and meantime expand into the interior center along with the main traffic road by fan shape as well as form relative centralism group spatial structure. The distribution of housing plots display four distribution characters that conclude the urban fringe layout, traffic road layout, and layout approaching hi-tech garden and natural resources as well as near university layout .At last, the article discusses the problem of human inhabitation environment and relative countermeasure during the housing spatial expansion.The urban residential space is the important context of urban geography and urban planners. This research is not only the important significance for the urban plan, innovation and integrative development, but also has the big guidance significances for the real estate developer and housing consumer.
