摘要
运用空间自相关、空间马尔科夫链方法对1987～2014年内蒙古自治区县域农业比重数据的时空分布及时空演变特征进行了研究。结果表明：①内蒙古自治区农业比重空间自相关性强且空间聚集现象明显；②农业比重存在区域趋同趋势，“低”水平县域趋同趋势有所加强，“高”水平县域趋同趋势有所减弱；③县域自身及其邻域同时向上转移的地区主要集中在蒙东以及蒙西的乌兰察布且呈收缩态势，县域自身或邻域有一方或双方均向下转移的区域绝大多数位于蒙西；④农业比重水平转移显著受到时间和区域背景的制约，区域趋同趋势在时间和空间上表现出不稳定与不独立的特征；⑤1987～2001年，农业比重低水平地区和高水平地区的区域背景对水平转移均起到了负面影响；2001～2014年，农业比重低水平地区的区域背景对水平转移起到了负面影响，而高水平的区域背景则产生了正面影响。这为内蒙古自治区不同时期、不同区域的区域趋同趋势存在及差异提供了空间上的解释。
Abstract
The spatial patterns and spatial evolution of agriculture share at county level were researched in Inner Mongolia Autonomous Region from 1987 to 2014, using spatial autocorrelation and spatial Markov chains.The results showed that the corresponding results demonstrated a strong spatial autocorrelation and an obvious spatial accumulation of agriculture share in Inner Mongolia Autonomous Region.The agriculture share had the tendency of region convergence, which was strengthened in low level counties and weakened in high level counties.The upward-ly transferring areas including the county as well as the neighborhood were mainly centralized the east regions of Inner Mongolia Autonomous Region and Wulanchabu ,the western city of Inner Mongolia Autonomous Region with a Shrinkage trend .The majority of the regions where ei-ther one of the county and the corresponding neighborhood or both transfer downward were located in the west of Inner Mongolia Autonomous Region.The transfer of the agriculture share was remarkably restricted by time and regional background and the trend of regional convergence behaved unstably and dependently in terms of time and space.During 1987 and 2001, negative effects on the level transfer resulted from re-gional background could be found in regions with both high and low agricultural share.The regional background of the region with low agricul-ture level negatively affected the level transfer, whereas active effects were generated from that of high level.This research provided adequate spatial explanation for the existence and difference of regional convergence of Inner Mongolia Autonomous Region in different periods and re-gions.
