The Urban Morphology Study Based On The Policies And Regulations

The urban construction in our country develops at a rapid speed: one year sees a change in appearances; and three years a major change. Consequently the evolution of urban morphology is fast and radical, demonstrating many new features, which are dizzying even dazzling. Urban space expands at a high speed and urban planning practice develops in an unprecedented manner. In this context, to explore the genetic mechanism behind the evolution of urban morphology is of theoretical and practical significance. The exploration of such genetic mechanism not only decides how we understand the urban morphology that has taken shape; it also exerts influences upon the ways and means by which urban morphology is shaped. Meanwhile our actions today will inevitably have a profound impact on urban morphology in the future. Urban morphology is generated during the process of historicaldevelopment. Behind the evolution of forms there hide a certain order and law of growth. Cities in different historical periods and different regions cannot escape the industrial development and economic promotion, while producing a variety of urban morphology. A comparative study on urban morphology in different countries leads to a finding that the generation of urban morphology is subject to laws and regulations. National policy guidance and regulatory system play a key role in guiding and controlling the formation and evolution of urban morphology. As a result, urban morphology is not just a spatial phenomenon, but a legal one. The study of urban morphology cannot be divorced from the legal soil in which it survives.The legal construction of urban planning has been gradually improved by various countries under the influence of political and economic situations in different historical periods, with the development of urban construction and strengthening of legal systems. Due to differences in national conditions and systems, the management systems employed by countries also vary. But their common feature is a legal way to control and guide the development of the city. Since the 1990s, the evolution of urban morphology in our country has been heavily influenced by state laws and regulations as well as local policies, as a result of which it shows many features different from Western classical mode. Without the analysis of laws and regulations, institutional environment and policy behavior, almost no reasonable explanation could be given for the variety of phenomena emerged in the evolution of urban morphology.The present thesis is organized around the legal characteristics of urban planning, analyzing the regulatory factors in the development of urban morphology and exploring the influence of policies, laws and regulations on urban morphology during the process of urbanization from the perspective of laws and regulations. The paper also clarifies the control system of urban planning in China and conducts a research on urban morphology within a framework formed by the system of laws and regulations, the statutory planning system and planning management system. The results show that the evolution of urban morphology can not do without the constraints of laws and regulations and technical specifications. The causes for why city planning is out of control have been investigated from a legal point of view; what is more, reflection is triggered on the rule of law in urban planning. The present study not only establishes a close contact with the physical space that domestic urban planning is highly concerned with, but also provides theoretical foundation for legalization of urban planning.
