摘　　要：为了探究城镇化与耕地破碎化空间相关特征,促进新型城镇化建设、耕地规模经营管理和土地资源的可持续利用,采用双变量空间自相关分析方法从人口、经济、生活和交通四个角度分析了不同城镇化水平下的耕地破碎化空间分异特征。结果表明:人口城镇化与耕地破碎化5个单项指标存在显著的空间负相关性;经济城镇化与耕地破碎化单项指标(景观分离指数)存在较弱的空间正相关性。人口城镇化和交通城镇化都与耕地破碎综合值存在空间负相关性。在双变量LISA图中,城镇化与耕地破碎化高-高型多分布在区域东部,而低-低型分布在西部边缘地带。In order to explore the spatial correlation characteristics of urbanization and cultivated land fragmentation （CLF）, and promote the new type of urbanization construction, cultivated land scale management and sustainable land resources use. In this paper, the population, economy, life and traffic were analyzed in different urbanization level. Then the correlation between urbanization and spatial differentiation characteristics of CLF was calculated by utilizing bivariate spatial autocorrelation method. The results showed that population urbanization was discovered to have the most significant negative correlations with five individual indicators of CLF, but economic urbanization had weak spa- tial correlation with the single index of CLF （DIVISION）. What＇s more, both population urbanization and traffic urbanization had negative correlation with CLF comprehensive value. In addition, the biva-riate LISA figures between urbanization and CLF had similar spatial characters. The high-high cluster mainly gathered in eastern area and low -low cluster distributed on the west edge.
