Polycentric city development boundary demarcating method

Abstract

The invention discloses a polycentric city development boundary demarcating method. The method includes the following steps: calculating the economic output value, the ecological services value and the social security value of agricultural land resources of a city, establishing scarcity correction coefficients and a polycentric city attraction inertia index model to improve the three values of theagricultural land resources, conducting automatic interpolation and balanced judgment on the more scientific and reasonable economic output value, ecological services value and social security valueof the agricultural land resources as well as the price of construction land of the city through a computer, and finally demarcating an ideal boundary, a moderate boundary and a limit boundary for development of the polycentric city. Through comprehensive utilization of scarcity and attraction inertia model, scientific demarcation of common polycentric city development boundaries in the process ofcity expansion can be carried out in a more reasonable manner, breaking limitations of demarcation of monocentric city development boundaries in the prior art.

Description

technical field [0001] The invention belongs to the fields of urban and rural planning, urban planning and land planning, and relates to an urban planning method, in particular to a method for demarcating the development boundary of a polycentric city. Background technique [0002] With the continuous acceleration of the urbanization process in our country, problems such as accelerated spatial sprawl, traffic congestion, environmental pollution and ecological damage, and social isolation highlighted in the rapid development of cities have become increasingly serious. How to scientifically and effectively curb the evolution of these unhealthy trends has become an important issue for the government. The focus of common attention with the academic community. As a complex giant system, a city is affected by many factors, and the interaction of various elements within the urban system has obvious spatial conflicts. The demand for construction land in the city continues to increas...

Problems solved by technology

[0003] Many achievements have been made in the delineation of urban development boundaries. After reviewing the existing research, it can be found that most of the existing research perspectives, technologies and methods focus on the delineation of single-center urban development boundaries, and fail to answer the question of urban development from a logical perspective. Theoretical basis for the delineation of development boundaries, and most of them ignore the impact of the more common polycentric phenomenon on urban development boundaries in the process of urban development, so that it is impossible to scientifically and rationally solve the problem of delineating the boundaries of polycentric cities, resulting in the existing technical methods for urban development. The delineation results of the development boundary are quite different from the actual regional development. Therefore, it is necessary to further explore the logical basis for the delineation of the urban development boundary, especially the technical methods for the delineation of the multi-center development boundary.
