Embodiment 1

[0035] Embodiment 1: A method for classifying urban color with natural environmental factors, artificial environmental factors and cultural environmental factors as the main influencing factors of urban color.

[0036] Step A: Establish an evaluation index system for urban color space sensitivity: Construct four levels of evaluation levels: the target layer is "determination of color-sensitive areas in urban space", and the criterion layer is "natural environment factors, artificial environment factors and cultural environment factors" , sub-criteria layer 1 includes "vegetation, water system, land use planning, traffic use planning, etc.", and sub-criteria layer 2 corresponds to more detailed classification indicators.

[0037] Step B: Summarize the geographical information data of each factor, standardize it, and transcribe it into ArcGIS; according to the overall planning of the research city, land use map, design of key areas, urban annals and other data, compare the target...

Embodiment 2

[0043] Embodiment 2: In this example, a central urban area is taken as the research object, and the purpose is to classify the urban elements at two levels of public facility land and roads by color control.

[0044] Step 1: Establish an urban color space sensitivity analysis system, which consists of four levels of evaluation levels. The levels from high to low are target level, criterion level, sub-criteria level 1 and sub-criteria level 2. The factors of each evaluation layer are shown in Table 1.

Abstract

The invention discloses an urban color grading method, a storage medium and a device, and belongs to the field of urban color planning. The method comprises the following steps: establishing an urban color space sensitivity evaluation index system by using an analytic hierarchy process (AHP), determining the weight of each factor by using an expert scoring method, and performing consistency check; collecting geographic information data of each factor, and inputting the geographic information data into ArcG IS for standardization processing; performing weighted integration on the geographic information data of each factor according to the weight of each factor to generate a single-factor evaluation grid; performing weighted superposition on each single factor evaluation grid to obtain a color sensitivity comprehensive evaluation grid; and in combination with urban land polygon vector data and urban road center line vector data, and simplifying the comprehensive evaluation grids to obtain different-level color control grade division results .

Description

technical field [0001] The invention relates to the field of urban color planning, in particular to a method for classifying urban color levels, a storage medium and a device. Background technique [0002] Improving the overall visual image of the city has increasingly become one of the core tasks of every city. In order to improve the overall visual image of the city more efficiently, it is necessary to find the color elements and entities that play a decisive role in the overall visual environment of the city, explore the areas in the city with better color control effects, and divide the color control level accordingly. [0003] In response to this demand, researchers have proposed a comprehensive evaluation method for color sensitivity in urban areas based on spatial sensitivity analysis. However, this method can only make an overall assessment of urban color space sensitivity in the form of a grid, and cannot make more specific and multi-level evaluations for specific ...
