Embodiment Construction

[0055] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0056] For ease of understanding, the theoretical basis is first explained:

[0057] Morphological Spatial Pattern Analysis (MSPA) is an image processing method that uses a series of morphological transformation graphics principles such as Vogt and others to segment, identify, and classify graphics by using erosion, expansion, opening operations, and closing operations. It divides the binary image into seven non-overlapping types: Core, Islet, Bridge, Loop, Edge, Perforation and Branch ). This method only relies on a single data (binary map) to obtain a reclassification map that emphasizes structural connections and accurate landscape structure types. It was earlier used in the study of forest landscape patterns and other aspects.

Abstract

The invention provides an ecological space network optimization method considering the rationality of planning layout and part configuration. Based on a GIS spatial analysis technology, in combination with spatial analysis software such as SPSS, GuidosToolbox and coneform 2.6, a binary Logistic regression model is utilized to analyze the effect of social and economic factors in the evolutionary process of the urban ecological space. And social economic factors are introduced into ecological space ecological network construction, and the territorial space ecological network is constructed based on the social economic factors, the ecological landscape type and the land utilization type in combination with the ecological part connectivity of the ecological space. According to the method, economic development level and population density factors are introduced, the influence effect of the factors in the spatial layout and quantity structure evolution process of territorial space ecological parts is analyzed, the factors serve as important influence factors of ecological network construction, and the territorial space ecological network is reconstructed; therefore, decision suggestions are provided for realizing space optimization layout and optimizing the territorial space ecological safety pattern for territorial space planning.

Description

technical field [0001] The invention belongs to the technical field of land space planning and land space governance space optimization, and mainly relates to an ecological space network optimization method of land space. Background technique [0002] Ecological space provides great support for the expansion and progress of the city and the ecosystem services of the city in the development of the city. Deconstructing the regional ecological space structure is an important part of optimizing the network layout of land space ecology-agriculture-urban space. With the development of urbanization, areas with concentrated population and rapid social and economic development have become important places for human economic activities, and the continuous strengthening of economic construction and land use has made the dependence on ecological space constantly strengthened. This also puts forward higher requirements for further optimizing the original spatial structure of the ecologi...
