Problems solved by technology

[0003] In the existing planning technology, the division of functions is generally determined by the multi-factor spatial overlay method. The theoretical basis is mainly based on Gadis’s “survey-analysis-planning” proposition, and the operation is derived from McHarg’s "Design combined with nature" mode, that is, in the planning operation process, the analysis method of transparent superposition of multi-factor diagrams is used to determine the spatial impact result

Embodiment

[0078] In this embodiment, taking the North Bund area of ​​Shanghai as an example, a method for functional zoning of urban blocks based on spatial clustering of principal factors is provided. The North Bund area starts from Dalian Road / Qinhuangdao Road in the east, Henan North Road in the west, Huangpu River / Suzhou Creek in the south, and Zhoujiazui Road in the north, with a total land area of ​​3.66 square kilometers. like figure 1 As shown, it specifically includes the following steps:

[0079] (1) Definition of spatial impact factors

[0080] Guided by the development orientation of the region, drawing on international experience and combining the specific conditions of the region, the main influencing factors of the spatial development framework of the North Bund area include waterfront shorelines, industrial clusters, rail transit stations, historical and cultural heritage, and large open spaces.

[0081] like figure 2 As shown, according to the morphological characte...

Abstract

The invention discloses a city block function zoning method based on multi-factor spatial clustering. The city block function zoning method comprises the following steps of firstly determining influence factors of a region spatial development framework, and then zoning influence ranges of the influence degree and the range attenuation mode on surrounding regions by each factor; carrying out correlation analysis on spatial influence factors, and judging whether spatial correlation relationship of different factors meets the conditions of space dimensionality reduction or not; then carrying out dimensionality reduction on multi-element data, and summarizing the various influence factors into a plurality of main factors which are spatially and regularly distributed through calculation; finally, judging basic characteristics of each region type according to standard deviation multiple of an average value of the main factors and initial spatial influence factors in each region type and a total average value of the main factors and the initial spatial influence factors in a target region, and determining city block function zoning. According to the city block function zoning method disclosed by the invention, summarizing and extracting on land use arrangement are carried out by taking objective evaluation as a basis by virtue of commonly-used metering analysis methods such as correlation analysis, main factor analysis and clustering analysis, and thus the city block function zoning can be more reasonable.

Description

technical field [0001] The invention relates to the technical field of urban and rural planning compilation, in particular to a multi-factor spatial clustering method for functional zoning of urban blocks. Background technique [0002] The normal operation of a city depends on the rational layout of various elements in space. "Book of Changes: Xici Xia": "Japan and China are the city, to the people of the world, to gather the goods of the world, to trade and return, and everyone gets what he wants." In modern society How to carry out the spatial layout of urban functions is the basic work of urban planning. [0003] In the existing planning technology, the division of functions is generally determined by the multi-factor spatial overlay method. The theoretical basis is mainly based on Gadis’s “survey-analysis-planning” proposition, and the operation is derived from McHarg’s "Design combined with nature" mode, that is, in the planning operation process, the analysis method o...
