基于熵权TOPSIS和耦合协调模型的四川省土地利用效益耦合协调关系及时空演变特征

Shuitu Baochi Xuebao
[目的] 从社会、经济、生态环境3个方面评价区域土地利用效益及其耦合关系有利于实现土地资源的合理配置及优化用地结构。[方法] 以四川省21个地市州为研究对象,利用熵权TOPSIS法和耦合协调度模型,构建了2010—2020年四川省土地利用效益的综合评价体系,并基于GIS技术,分析了土地利用的社会、经济、生态环境效益及其耦合协调关系的时空演变特征。[结果] (1)四川省各地市州的土地利用综合效益整体上呈上升趋势,空间上具有"西北高东南低"的空间格局;土地利用的经济、生态环境效益整体上具有上升趋势 ...

關於二元樹上一階馬可夫平移之條型熵研究

Petersen 和Salama(cf. [1], [2]) 證明d 維樹平移中拓樸熵的存在性, 之後獨創條型法取最左邊的分支作為基礎, 估算黃金平均規則在d 維樹上的條型熵, 並發現條型熵會收斂至拓樸熵的性質。本篇論文運用條型法, 將黃金平均平移轉換為其高次區塊平移, 去計算在二元樹上沿著任意路徑的條型熵 ...
