Problems solved by technology

Since the living circles defined by each public service facility or each community are different, it is also impossible to determine the total number of community living circles and their boundaries at the urban scale; method (3), that is, the demarcation of the boundaries of the living circles based on residents’ daily activities The method is the measurement method closest to the original intention of the community life circle. However, the current application of this method mainly relies on GPS data, which is costly and has limited samples. full view of the circle
In summary, the existing methods still have technical problems such as insufficient measurement accuracy, high cost, and low efficiency.

Embodiment 1

[0043] This embodiment provides a community living circle boundary measurement method, such as figure 1 As shown, the method includes the following steps:

[0044] 1) Divide the research object into several plots with the centerline of the road as the boundary, and calculate the distance between the plots. The distance between the plots is the boundary distance between the plots, and the distance between adjacent plots is zero.

[0045] 2) Obtain the contact matrix between each block based on the mobile phone location service data LBS, based on the contact matrix, the corresponding contact network N can be obtained through the network analysis software; then according to setting multiple distance constraints d 1 、d2 、d 3 ... d n , and get multiple effective contact networks N 1 , N 2 , N 3 ...N n .

[0046] The mobile phone location service data is the mobile phone location service track data of all users on a working day.

[0047] The contact matrix is ​​obtained thr...

Embodiment 2

[0062] This embodiment provides a community life circle boundary delineation system, including plot division and distance calculation module, effective contact network screening module and result generation module, wherein, the plot division and distance calculation module is bounded by the center line of the road The research object is divided into several plots, and the distance between the plots is calculated; the effective contact network screening module obtains the contact matrix between the plots based on the mobile phone location service data, and through the setting of multiple distance constraints, multiple Effective contact network; result generation module, based on the complex network algorithm, clusters the contact strength of the effective contact network, selects the clustering results that match the set requirements, and obtains the boundary measurement results of the community life circle. All the other are with embodiment 1.

Embodiment 3

[0064] This embodiment provides a computer device, including a processor and a memory for storing a program executable by the processor. When the processor executes the program stored in the memory, the method for measuring the boundary of the community living circle as described in Embodiment 1 is implemented.

Abstract

The invention relates to a community life circle boundary measurement method and system, computer equipment and a storage medium. The community life circle boundary measurement method comprises the following steps of: 1) dividing a research object into a plurality of land parcels by taking a road center line as a boundary, and calculating the distances between the land parcels; 2) acquiring a connection matrix among the land parcels based on mobile phone position service data, and screening to obtain a plurality of valid connection networks through a plurality of set distance constraints; and3) clustering the connection strength of the valid connection networks based on a complex network, and selecting a clustering result matched with a set requirement to obtain a boundary measurement result of a community life circle. Compared with the prior art, the community life circle boundary measurement method and the system can effectively improve the boundary measurement accuracy, and have the advantages of high efficiency, low cost, wide application range and the like.

Description

technical field [0001] The invention relates to the field of quantitative measurement of community life circles, in particular to a method, system, computer equipment and storage medium for boundary measurement of community life circles. Background technique [0002] People's life circle is mainly the community. The community is the basic unit of residents' life. The configuration of its service facilities directly affects the quality of life and lifestyle of residents. It is an important spatial unit in the process of urban stock renewal and the focus of community planning. The boundary delineation of the living circle is the key point and difficulty in the study of the community living circle. On the basis of accurately delineating the boundary of the living circle, it is possible to allocate community public service facilities more reasonably and improve the living experience of residents. [0003] The existing boundary delineation methods are based on administrative boun...
