Research On The Scale And Morphology Of Urban Land Expansion

In recent years, the scale of urban construction and the urban land have been substantially enlarged with the quickening pace of economic growth and urbanization. So how to by scientific and rational enlarged the urban land, accelerate the social prosperity and sustainable growth of our society is pop of scholar's researches. The scale of urban and the urban morphology are of great significance part of the urban system, so the scale of urban and the urban morphology is a whole, we should analyze and forecast it synthetically. It offers scientific gist for making rational scale of urban and harmonious space morphology, still have very high theoretical value and reality instruction significance.This paper on the basis of literature review, makes analyze on the scale and morphology of urban land expansion of Jiangbei district. It includes eight parts:Part one is preface, includes the background of the article and the significance of study, study process about the subject, and the target, content, method of study.Part two introduce essential theories of urban land expansion.Part three is analyzing urban land expansion the scale and morphology of urban land expansion. On the basis of the scale of Jiangbei district urban land, exercise GIS technique, exercise diversified correlative indexes, make quantitative and integrative analyze on the scale and morphology of urban land expansion. By more analyzing on these indexes, make scientific evaluation on the actuality of urban land expansion, find out its traits and problems, and analyze the reasons.Part four is analyzing modes of urban land expansion. On the basis of summarizing four modes of urban land expansion, discuss the mode of Jiangbei urban land expansion, educe the primary mode now, and according as urban developing situation, forecast the intending mode of urban land expansion.Part five is analyzing the influencing factors of urban land expansion. The influencing factors of urban land expansion include natural factor and social economical factor. On the basis of factors, concretely analyze diversified influencing factors of Jiangbei urban land expansion.Part six is forecasting the urban land expansion. This paper discuss the forecasting methods of urban land expansion qualitatively and quantitative. Especially on the quantitative forecast aspect, forecast the urban land expansion by method of factor forecasting, method of trend extrapolating and method of CA model from different angle. On the basis of actual complexion in the forecast area, choose appropriate forecast methods, and make quantitative forecasting for the scale and morphology of urban land expansion of Jiangbei district.Part seven is the strategy of Jiangbei urban land expansion. On the basis of anterior parts, it summarizes the principle and conceiving of future Jiangbei urban land expansion, and puts forward pertinent policy and suggestion for actualize ensuring urban land expansion orderly.Part eight sums up study conclusions and productions, namely quantitative and synthetical evaluating and forecasting the scale and morphology of urban land expansion, and puts forward several problems for more studying.
