Embodiment Construction

[0120] In order to describe the technical content of the present invention in detail, the following will be described in conjunction with the embodiments and accompanying drawings.

[0121] Taking the block division of the Hankou area of ​​Wuhan as an example, the first step is to divide the Hankou area of ​​Wuhan into 462 minimum division units, such as figure 2 As shown, and calculate the area of ​​each minimum division unit, and normalize, the maximum value after normalization is 1, and the minimum value is 0.1767;

[0122] In the second step, use formula (1) and formula (2) to calculate the relative population size, such as image 3 Shown, and use the formula (3) to normalize it, the maximum value after normalization is 1, and the minimum value is 0.1952;

[0123] The third step is to use POI data and formulas (4) and (5) to calculate the functional mixing degree of each smallest segmentation unit, such as Figure 4 As shown, and normalized, the maximum value after norm...

Abstract

The invention relates to the technical field of spatial region planning, in particular to an intelligent division method for urban blocks. The method comprises the following steps: (1) dividing a city into a plurality of minimum segmentation units, and calculating the area; (2) estimating the population number of each minimum segmentation unit; (3) calculating the function mixing degree of each minimum segmentation unit; (4) constructing block constraint conditions, dividing the city into a plurality of blocks, and classifying each minimum segmentation unit into each block; (5) constructing a block area balancing objective function, a block population balancing objective function, a block function mixing degree maximization objective function and a block boundary compactness highest objective function; and (6) constructing a comprehensive objective function. According to the method, the urban space is divided into the blocks by using an intelligent division method, the population quantity balance and the area relative balance of each block can be ensured, the internal functions of the blocks are relatively perfect, and the method has important significance in the fields of urban space optimization, refined treatment and the like.

Description

technical field [0001] The invention relates to the technical field of spatial area planning, in particular to a method for intelligently dividing urban blocks. Background technique [0002] A block is a place surrounded by urban road networks with a certain scale and scale. It is the basic unit of the city and an important carrier of people's daily life. Block optimization can improve the living environment and improve urban governance capabilities. Blocks contain rich urban morphology and cultural connotations, and are also the basis for the continuation of urban culture and urban life. At present, streets and communities are mainly used as basic human settlement management units and census units in China, while urban communities and streets are generally based on evolutionary planning, and there are problems such as unreasonable spatial structure settings and insufficient supply of public products and services. In the final analysis, the main reason is that the spatial ...
