Embodiment Construction
[0035] The technical solution of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.
[0036] The development of the three-life space is carried out through the exchange of materials and energy between spaces, and can be carried out through various indicators of the development status of the three-life space. Considering the availability of data, the present invention selects from the statistical yearbook to reflect the three-life space. The index sets of the respective changes in the subspaces are represented by the following formula:
[0037] M={P, L, E} (Formula 1)
[0038] In the formula, M represents the three life space index sets, P represents the various indexes reflecting the changes of the production space, L represents the various indexes of the living space changes, and E represents the various indexes of the ecological space changes. Various indicators are obtained from the Statistical Yearbook. B...

The invention provides a regional three-generation space coupling quantitative measurement method. The method comprises the steps: carrying out the three-generation space division: dividing the regional land utilization type into three-generation spaces according to a two-stage leading function, and building a space weight matrix, wherein the three-generation spaces comprise an ecological space, aproduction space and a living space; Formulating and processing three-generation spatial change indexes: selecting an index set reflecting three-generation spatial change through a principal component analysis method, and performing standardization processing to obtain a standardized index set; Defining a variation coefficient as a ratio of a standard deviation to an average value for measuring arelative difference level of development of a certain index in the region; And constructing a coupling quantitative measurement model to realize extraction and judgment of the coupling degree of thethree-generation space. The method can automatically and quantitatively reflect the coupling degree of the ecological space, the production space and the living space of the research area, is high inefficiency and accurate in analysis, and has important significance for evaluating the harmony of the development of the three-generation space of the area and diagnosing the imbalance of the area space.
Description
technical field [0001] The present invention relates to the technical field of three-life space automatic analysis, in particular to a quantitative measurement method and system for regional three-life space coupling. Background technique [0002] "Coupling" (coupling) refers to the relationship between two or more systems that rely on each other, coordinate with each other and promote each other through various interactions. For reference, please refer to the literature: Shi Jiaying and Wang Yun, Central Park, New City, Yangtze River Delta Region Research on Coupling Relationship with Urban Space. Journal of Shanghai Jiaotong University (Agricultural Science Edition), 2018(03): pp. 27-32+52. According to the dominant function of the land, an area can be divided into ecological space, production space and living space. The three spaces are interlaced and interdependent, coordinated and promoted through the exchange of materials and energy between spaces during the developmen...
