摘要： 运用主成分分析、多目标加权求和模型、马尔可夫链和ESDA方法，在GIS 技术支持下，基于吉林省中部粮食主产区24 个空间单元2000 年、2003 年、2007 年3 个时间断面的数据，探讨该区城乡综合发展水平时空格局演变特征及其动力因子。研究结果表明：① 区域城乡发展存在“俱乐部趋同”现象，城乡综合发展水平的空间差异趋于扩大；② 区域城乡综合发展水平“两极分化”明显，高水平空间单元集中在5 个地级市辖区，低水平空间单元进一步向哈大铁路沿线集聚，并在其北侧形成“哑铃”状连续分布区，该区域有可能陷于强者愈强，弱者恒弱的“马太效应”；③ 主成分分析结果表明，城乡经济实力、空间区位、居民收入等是吉林省中部粮食主产区城乡综合发展水平时空格局演变的主要动力因子。

Abstract: By the methods of Principal Component Analysis, Multi-objective Weighted Model, Markov Chains and ESDA, and based on the data of 2000, 2003 and 2007 of 24 spatial units in the major grain-producing areas of central Jilin Province, the spatio-temporal pattern change and its driving factors of urban-rural integrated development level were discussed. The results are shown as follows. First, there exists a phenomenon of “Club Convergence” in regional urban-rural development, and the spatial discrepancy of urban-rural integrated development level in the study area has become greater; Second, there was an obvious trend in the “Polarization”of urban-rural integrated development level, i.e., the higher level spatial units were concentrated in the five prefecture-level municipal districts, and the lower level spatial units were mainly in the central region along the Harbin-Dalian Railway, thus formed a “Dumbbell”-shaped continuous distribution area. It may fall into the“Matthew Effect”that the strong will become stronger and the weak will be constantly weaker. Finally, according to the Principal Component Analysis, it can be concluded that the economic strength, spatial location and income level of residents were the main driving factors of spatio-temporal pattern change of the urban-rural integrated development level in the major grain-producing area of central Jilin Province.

Key words: index of urban-rural integrated development level, Markov Chain, ESDA, driving factors, the major grain-producing area of central Jilin Province
