Analysis and Dynamic Prediction of Coupling Law between Land Use and Ecological Environment Based on Grey Model——Taking Baoji City as an Example
The grey model has the advantages of low data requirements,high accuracy,simple operation,wide applicability,and good prediction performance,and the GM(1,1)model is currently the most widely used grey model.Taking Baoji city as an example,the evaluation index system is established,and the GM(1,1)model is used to analyze the coupling coordination between land use and ecological environment in the study area from 2005 to 2020,and the coupling coordination between the two is predicted from 2021 to 2025.The results indicate that from 2005 to 2020,the coupling coordination degree between land use and ecological environment in Baoji city showed an upward trend,and the type of coupling coordination gradually shifted from moderate imbalance to good coordination.According to predictions,from 2021 to 2025,the comprehensive index of land use and ecological environment in Baoji city will continue to rise,with the former still higher than the latter,but the development of ecological environment lags behind.The research results help clarify the coupling law between regional land use and ecological environment,thus providing important support for scientific decision-making to promote high-quality regional development.
