基于CA-Markov模型和景观格局的生态保护红线评估效果分析

Spatio-temporal analysis of ecological redline optimization effect based on CA-Markov model and landscape pattern indicators

针对生态保护红线对城镇开发建设的约束效果,应用CA-Markov模型预测2020年、2025年、2030年重庆市江北区土地利用类型分布情况,构建了景观格局评价指标体系,计算并分析了各年份景观格局指标结果,并应用熵权法计算进行了综合评价,结果表明生态保护红线优化评估效果将在2025年初见成效,从长期角度出发,优化后的生态保护红线优于现行红线。

By coupling CA-Markov model and landscape pattern indicators,this study revealed the optimization effect of the ecological redline.Contrasted with non-optimized redline with entropy weight method.The results indicated:the optimization effect will be achieved in 2025,and from a long-term perspective,the optimized ecological redline is superior to non-optimized redline.
