Problems solved by technology

[0004] However, previous studies on the identification of urban fringe areas have limitations in terms of scope of application, identification efficiency, and subjective factors affecting the results.
Moreover, the previous research on the identification of urban fringe areas could not separate the noise generated by the mutation points, which would have a certain impact on the identification results.

[0118] 1. Research Methods

[0119] 1.1 Selection of indicators and determination of scale

[0120] 1.1.1 Index selection

[0121] The selection of indicators is mainly divided into two categories: single indicator and multiple indicators. Among them, multiple indicators can interpret the characteristics of urban fringe areas from various aspects, but there will inevitably be correlations between indicators, which will affect the scientific nature of the indicator system. The single index is not affected by the correlation. ...

Abstract

The invention provides a method for identifying and verifying an urban marginal area by using cloud data. The method comprises the following steps: S1, selecting characteristic indexes capable of reflecting the urban marginal area; s2, finding mutation points and connecting the mutation points so as to determine the range of the urban marginal area; and S3, verifying the obtained spatial distribution range of the urban marginal area. According to the method, the influence of subjective factors can be reduced, noise can be effectively eliminated, and the spatial range of the urban marginal area can be accurately identified. Compared with a conventional verification method based on data analysis of night light, vegetation indexes and the like, the result obtained by selecting a certain number of sample points for verification is more reliable.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to a method for identifying and verifying urban fringe areas using cloud data. Background technique [0002] The purpose of urbanization is to promote the integrated development of urban and rural spaces in order to achieve the common progress of urban and rural people. However, urbanization will have an impact on the ecological environment, resource allocation and many other aspects. At present, a large number of studies have focused on urban and rural land cover change and regional climate, but neglected the importance of urban fringes. In 2019, China proposed to improve the system and mechanism of urban-rural integration development, and the topic of how to promote the high-quality development of urban-rural integration in the new era has attracted more attention. And the urban fringe area is also the fusion area of ​​the city and the countryside, and it will also have i...
