Analysis and control method of urban form based on three elements of plane pattern and fractal calculation

Abstract

The present invention discloses an urban morphology analysis and controlling method based on three elements of the plane pattern and fractal calculation. The method comprises: obtaining city map research data, dividing a plurality of typical research areas, decomposing the three elements of the plane pattern to carry out fractal calculation respectively so as to obtain the fractal dimension and obtain the histogram of the fractal dimension of the three elements of the plane pattern in different research sub-areas; summarizing fractal dimension features of the three elements of the plane pattern in the research area; putting forward optimization suggestions; and carrying out reasonable control on the urban plane pattern in the urban planning design and management. According to the method disclosed by the present invention, the three-element framework of the plane pattern is combined with the fractal calculation method, and reasonable control is carried out on the urban plane pattern by using the quantized data of the fractal dimension; and at the same time, by combining the traditional urban morphology research method with the new technical means such as the GIS, the operation process is simplified, the workload is reduced, the research efficiency is improved, and the calculation results are efficient and accurate.

Description

technical field [0001] The invention belongs to the technical field of urban planning and urban management, and in particular relates to an urban form analysis and control method based on three elements of plane pattern and fractal calculation. Background technique [0002] The study of urban morphology originated from Western human geography. By observing and studying the organic growth mechanism of cities, morphological methods are used to analyze the social and physical environment of cities. A holistic view of urban form". Its development process from the initial town plan as a research subject, experienced the update of urban morphology theory before and after World War II, and finally developed into different schools of morphology. Early studies on urban planar patterns were limited to considering only streets or street spaces, and the internal structure of blocks was usually ignored, as well as the various phenomena that were covered up in the process of urban expans...

Problems solved by technology

[0004] Using fractal calculation as a quantitative method can describe the growth, self-similarity and self-organization characteristics of the city. It has been used in the study of urban form in the 1990s. However, it is too abstract and mechanical to simply use this method to analyze the urban form.
