Abstract
The invention discloses an analysis method of ecological process change, which determines regional data through remote sensing images, solves the technical problems of insufficient data collection and insufficient model input source data in the prior art, and determines the influencing factors in combination with environmental factors to solve the problems in the prior art The input data does not take into account the technical problems of the surrounding environmental factors in the desert area. In the process of deduction using cellular automata, the seed cells and ordinary cells are determined first, and then the positive and negative growth probabilities are determined. The desert ecological process is deduced, and the deduction results are obtained, and the spatial analysis and evaluation of the simulation results of the desert ecological process deduction is realized by using cellular automata.
Description
technical field [0001] The present invention relates to the technical field of desert ecological process deduction, in particular to an ecological process change analysis method, device, medium and terminal equipment. Background technique [0002] Desert, also known as desert, refers to arid areas with scarce vegetation or lack of water; desert ecology refers to the ecological environment of desert areas. Generally, the average annual precipitation in desert areas is below 250 mm. The lack of water limits the growth of green plants and all animals and microorganisms that directly or indirectly depend on green plants for a living, resulting in sparse distribution of plants, which can survive in desert areas. The plants are almost all xerophytic species. [0003] The deserts in our country are mainly distributed in the Northwest and Inner Mongolia. In order to improve the ecological problems of deserts, the government and the private level have organized personnel to go to de...
