摘　　要：开展土地整治投资的时空分异研究,对把握其投资强度、空间格局以及发展态势,提高资金投入产出效益具有重要的理论和现实意义。该文基于2006-2012年农村土地整治监测监管数据,以县域为评价单元,分析了"十一五"以来中国土地整治项目投资强度、区域构成和投资类型,而后结合重心分析和空间自相关模型,研究了投资重心转移和空间格局演变特征,得出以下结论:在空间分布上,土地整治投资呈沿海高于内地、经济发达区高于欠发达区、低纬地区高于高纬地区,中、东部地区是土地整治投资的重点活跃区;在投资类型上,土地整治项目由开发投资主导,开发、整理以及复垦投资型县区空间集聚特征显著,而综合投资型县区空间分布较为零星、分散;在重心转移方面,土地整治投资重心偏向东部沿海,南北向未发生显著变化,东西向呈现从东部沿海往中西部内陆转移的趋势;在空间关联上,土地整治投资在空间分布上存在显著正相关性,长江下游、洞庭湖平原和四川盆地东部是整治投资的高-高集聚区,南疆、青海、西藏、川西、滇南和蒙东为整治资金的低-低集聚区。该研究可为宏观层面制定土地整治规划、引导土地整治资金投向、开展绩效评价等提供决策参考。As the basis for realizing the objectives and tasks of land consolidation, land consolidation projects investment is not only the precondition for implementing the land consolidation projects, it is also an important standard to measure the development level of regional land consolidation. Studies of the spatio-temporal differentiation of land consolidation investment have revealed important theoretical and practical significance in grasping its investment intensity, spatial pattern, and development trend, effectively increasing capital input and output efficiency. Based on the data acquired from the dataset of a consolidation project from 2006 to 2012 by the Ministry of Land and Resources, this paper first analyzes the development trend of land consolidation from investment intensity and regional structure to the type of investment in China. Then, by combining a gravity center model with a spatial autocorrelation model, ArcGIS and Geoda software was used to analyze the gravity center and spatial correlation of land consolidation and produced a LISA cluster map. The results showed that：1） In terms of spatial distribution, land consolidation investment at the county level in the southeast coastal area ranks higher than that of the Chinese inland, developed areas rank higher than less developed regions, low latitudes areas rank higher than their counterparts, and the investment is mainly focused in the eastern and central region of China, where is an active area of socio-economic development. 2） In terms of investment types, the percentage of the county that is defined as land development investment was in a dominant position and fluctuated inconspicuously year after year. To be more specific, in the counties that are defined as land development, the arrangement or reclamation investment type has remarkable characteristics of spatial agglomeration. However, the counties which are defined as land comprehensive investment type is not obvious in the spatial agglomeration, but is considerably scattered throughout
