摘要
[目的]研究阿克苏地区土地集约利用的时空动态。[方法]以阿克苏地区8县1市为研究区,从社会-经济-生态3个层面选取12项指标构建SEE模型,结合变异系数法和主成分分析法确定指标综合权重,进而研究2012—2017年阿克苏地区土地集约利用时空动态变化,并对“社会-经济-生态”协调性水平进行分析。[结果]时间尺度上,阿克苏地区在2012—2017年的土地集约利用水平有显著的波动上升,由2012年土地粗放利用到2017年基本都实现土地中度集约利用;空间尺度上,地区土地集约利用水平具有空间差异性和聚集性,其中阿克苏市土地实现高度集约利用;土地集约利用综合水平和协调度水平2组数据的线性走势有极大的一致性,得到其Pearson相关性系数为0.664,两者相关性显著。[结论]阿克苏地区可以结合各县市的实际情况,采取不同的土地利用管理措施,提高社会、经济、生态三者间的协调度,进一步加强地区土地集约利用。
[Objective]To study spatial-temporal dynamic of land intensive use in Aksu area.[Method]Aksu region was taken as the research area and it has 8 counties and 1 city,12 indicators were selected from the three levels of social-economy-ecology to build the SEE model,and comprehensive weights of indicators were determined by combining the coefficient of variation method and principal component analysis,so as to study the spatial-temporal dynamic changes of land intensive use in Aksu region from 2012 to 2017,and to analyze the coordination level of“social-economy-ecology”.[Result]In terms of time scale,the level of intensive land use in Aksu region fluctuated significantly from 2012 to 2017,and the extensive land use in 2012 to 2017 basically achieved moderate intensive land use.On the spatial scale,the regional land intensive utilization level has spatial difference and aggregation.The linear trend of the two sets of data of comprehensive level and coordination level of land intensive use shows a great consistency,and the Pearson correlation coefficient is 0.664,indicating the correlation is obvious.[Conclusion]Aksu region can take different land use management measures according to the actual situation of each county or city,improve the coordination among society,economy and ecology,and further strengthen the intensive use of land in the region.
