ModelLing of the impact of land planning and development on regional ecological environment

In order to clarify the impact of land planning and development on regional ecological environment, a modelling study on the impact of land planning and development on regional ecological environment is conducted. The spatial comprehensive change index of land planning and development is determined, and the regional ecological security evaluation index and weight is calculated, so that the sensitivity of the regional environment in the process of land planning and development is determined. According to the sensitivity analysis results, the impact model of land planning and development on the regional ecological environment is built. The input of the model is the land investigation and statistical data, and the output is the impact degree score. The experimental results show that the accuracy of ecological security analysis in the sample area is always higher than 90%, and the error of regional ecological security is controlled below 5%, which verifies the advantages of this model.
