Embodiment Construction

[0070] According to the attached figure 1 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions and characteristics of the present invention can be better understood.

[0071] see figure 1 , a method for building a spatial pattern model of urban ecological security in an embodiment of the present invention, comprising the steps of:

[0072] S1: Use the state space method to analyze the ecological space security state of the target city to obtain the first analysis result;

[0073] Specifically, step S1 further includes steps:

[0074] S11: Count the ecological land area of ​​each district and county in the target city, and obtain the statistical data of ecological land;

[0075] S12: Statistics of the ecological and environmental load data of human behavior in each district and county of the target city. The ecological and environmental load data of human behavior includes regional GDP, regional population and compreh...

Abstract

The invention provides an urban ecological safety spatial pattern model construction method. The method comprises the steps that S1, a state-space method is utilized to analyze the safe state of ecological space of a target city to obtain a first analysis result; S2, an ecosystem service function is utilized to analyze the service ability of the ecological space of the target city to obtain a second analysis result; S3, a geographic information system is utilized to analyze network performance of the ecological space of the target city to obtain a third analysis result; and S4, an urban ecological safety spatial pattern model of the target city is constructed according to the first analysis result, the second analysis result and the third analysis result. The urban ecological safety spatial pattern model construction method has the advantages of high reliability and visualization.

Description

technical field [0001] The invention relates to the technical field of ecological security, in particular to a method for constructing a spatial pattern model of urban ecological security. Background technique [0002] Since the Industrial Revolution, human activities and industrialization have seriously deteriorated the global environment. Land use changes caused by human activities lead to changes in the area, spatial distribution and pattern of various terrestrial ecosystems, resulting in a series of problems such as habitat and structure fragmentation, changes in biogeochemical cycle processes, environmental pollution, and changes in water cycle processes. From a global perspective, global ecological disasters and environmental crises are seriously threatening the survival and development of human society. A series of serious ecological and environmental problems warn that the living environment of our human society is degrading. These degradations affect the quality o...
