Embodiment Construction

[0044] The specific technical solutions of the present invention are described in conjunction with the examples.

[0045] The frame diagram of the "three life" space optimization method adopted by the present invention is as follows: figure 1 shown.

[0046] This example takes Puge County, a national key ecological function zone, as an example, and takes 2030 as the time node, and simulates the spatial quantity structure and pattern of its "three life" according to the above method.

[0047] 1. Simulation of "Three Lives" spatial quantity structure

[0048] According to the equivalent table of ecological service value per unit area of ​​China's terrestrial ecosystems, combined with the actual situation of the region, connect each spatial type with its closest ecosystem type. Then, using the main food crops in Puge County from 2010 to 2014 to calculate the functional service value of food production per unit area of ​​agricultural production space, the ecological economic val...

Abstract

The invention belongs to the technical field of ecological functional areas, and particularly relates to a three-generation space optimization method based on external ecological function positioning,which comprises the following steps: (1) simulating a three-generation space quantity structure, wherein the three-generation space quantity structure is constructed by taking maximum ecological system service value as a target according to national key ecological function area requirements, and is obtained through a gray linear programming model; (2) configuring a three-generation space pattern;constructing a MLP-CA model by combination of multi-layer neural network and cellular automaton,wherein the model comprises two modules, namely a training module and a simulation module; in the training module, the trained network is utilized to automatically obtain internal conversion rules, the external conversion rules are superposed, and then the conversion rules are input into the simulationmodule to complete the three-generation space simulation operation process. According to the method, three-generation space optimization under ecological function positioning is highlighted, and synchronization of three-generation space quantity simulation and pattern configuration is realized.

Description

technical field [0001] The invention belongs to the technical field of ecological function zones, and in particular relates to a space optimization method for "three life" based on external ecological function positioning. Background technique [0002] As an important carrier of all social and economic activities of human beings, the use of land is essentially the transformation of the earth's surface by human beings, which determines the state of the ecological system environment, economy and social functions, and is related to the improvement of human well-being and sustainable regional development. It is an important content of land science research. From a functional point of view, land functions include three types of functions: production, life, and ecology, covering biophysical processes, direct and indirect production, and satisfaction of spiritual, cultural, leisure, and aesthetic needs. product of coupling. Each function has its corresponding space, which are pro...
