Embodiment 1

[0092] The present invention aims at the multi-category land use change simulation problem and integrates the advantages of the biodiversity model. Through the combination of the intelligent algorithm and the uncertainty model, the method can more accurately mine the relationship between the driving force factor and the land use change, and is more accurate. It truly reflects the process of land use change, and can more accurately simulate land use in future scenarios; and then quantitatively evaluates the impact of land use on biodiversity in future scenarios through ecosystem service models, species distribution models, and biodiversity index models. To determine whether the target requirements in different scenarios are met.

[0093] Based on the above purpose, the implementation process of the present invention will be explained below in conjunction with specific implementation data.

Abstract

The invention discloses a change scene simulation method based on an FLUS model and a biodiversity model. The method integrates the advantages of an old land utilization simulation model, eliminates error transmission, and improves parameters with indefinite practical significance in the model. A neural network algorithm introduced into the FLUS model is used for calculating the distribution probability of various types of land, and then a roulette mechanism is used for introducing competition of land utilization types, so that combination of an intelligent algorithm and an uncertainty mechanism is realized, and meanwhile, the method is applied to future land utilization scene prediction; finally, a simulation result with the accuracy higher than that of the old land utilization simulation model is obtained with less data, fewer parameters and higher speed; an ecological system service model, a species distribution model and a biodiversity index model in the biodiversity model are used for calculating each index, so that the influence of land utilization on biodiversity in a future scene can be quantitatively evaluated; by setting target requirements under different scenes, land utilization meeting scene targets can be obtained through simulation.

Description

technical field [0001] The invention relates to the technical fields of geographic information science, urban planning and ecological environment, and more specifically, relates to a method for simulating changing scenarios based on a FLUS model and a biodiversity model. Background technique [0002] Changes in human activities and natural factors drive changes in land use, which has a huge impact on the ecological environment. Therefore, how to assess the impact of land use change on biodiversity has gradually attracted attention. Indicator assessment, model simulation and scenario analysis are three common methods in biodiversity assessment. Scenario analysis methods are used to formulate questions and hypotheses. Model simulation methods are used to analyze how and why biodiversity changes under the assumptions set by the scenario analysis. The indicator evaluation method is used to express the analysis results and changing trends of the model. In recent years, the sp...
