| 摘 要： | 基于多源遥感数据提取投入产出数据，采用考虑非期望产出的超效率EBM模型对2000—2015年山东省县域生态效率进行测度，在此基础上采用核密度估计、空间自相关等方法对山东省县域生态效率的时空特征进行分析。研究表明：①山东省县域生态效率呈现波动式发展趋势；高值区与低值区存在显著空间分化，胶东半岛与济南都市圈构成高值集聚区，鲁西北、鲁西南、鲁南地区形成低值连绵带；②山东省县域生态效率无明显的两极分化现象，处于高值区、低值区的县域生态效率值变化较大，生态效率空间非均衡性逐渐扩大；③山东省县域生态效率存在显著空间正相关，且空间集聚性呈现增强态势；县域生态效率存在空间俱乐部趋同特征。 |

| Abstract: | Input-output data are extracted based on multi-source remote sensing data,we used undesirable-output super efficiency EBM(Epsilon-based Measure)model to measure eco-efficiency of the country from 2000 to 2015 in Shandong Province.On this basis,we used kernel density estimation,spatial autocorrelation method to analyze spatial-temporal characteristics of county eco-efficiency in Shandong Province.The results shows:(1)Eco-efficiency of the country shows a fluctuating development trend in Shandong Province;There is obvious spatial disequilibrium in eco-efficiency of high value area and low value area,Jiaodong peninsula and Jinan metropolitan area constitute high-value cluster area,and low-value continuous zone is formed in the northwest,southwest and south of Shandong Province.(2)There is no obvious polarization in county eco-efficiency in Shandong Province,eco-efficiency of the county in high value areas and low value areas vary greatly and spatial agglomeration has an increasing tendency,spatial disequilibrium of eco-efficiency is gradually expanding.(3)There is an obvious positive spatial correlation in county of eco-efficiency in Shandong Province;Eco-efficiency of the country has characteristics of spatial club convergence. |
| Keywords: | eco-efficiency county unit Super-EBM model multi-source remote sensing data Shandong Province |
