摘 要:运用熵权TOPSIS法和ArcGIS空间分析等方法,对四川省21个省市(州)2005—2014年的土地生态经济系统稳定性状况进行评价,结果表明:1)在2005—2014年间,四川省各市(州)的土地生态经济系统稳定性都逐渐提升,省平均水平由2005年的0.293增长到2014年的0.579;2)各市(州)土地生态经济系统稳定性绝对差异有所增大,但相对差异逐渐减小,且空间自相关性不明显;3)四川省土地生态经济系统稳定性空间分布格局在不断演变,由2005年川东一个高值区演变为2008年川东和川南2个高值区,且以川南为首.The improved TOPSIS and ArcGIS spatial analysis methods were used to evaluate the stability of the land eco-economic system of 21 cities in Sichuan Province from 2005 to 2014. The results showed that: 1) from 2005 to 2014,the stability of land eco-economic system in Sichuan had risen,the average level increased from 0. 293 to 0. 579; 2) the absolute difference between the cities had increased a little,but the relative difference had decreased,and the spatial autocorrelation had been weak; 3) The spatial pattern of the land eco-economic system in Sichuan province has been constantly changing. In 2005,Sichuan had only one high-value area which lied to the east of Sichuan. Since 2008,Sichuan has added a high-value area which lied to the south of Sichuan and became the top one.
