摘　　要：研究目的:探索耕地细碎化与耕地集约利用水平之间的空间相关关系。研究方法:采用Jenks自然断点法分析耕地细碎化程度与耕地集约利用水平的空间分异特征,运用空间自相关法分析两者之间的空间聚集状态并对其进行空间耦合分析。研究结果:(1)耕地细碎化的空间聚集状态与耕地集约利用呈现相反分布趋势;(2)斑块面积指数、形状指数与耕地集约利用的各项指标均有一定的耦合关系,而斑块分散指数与集约利用指标的耦合相关性不强;(3)耕地细碎化与耕地集约利用的耦合关系在不同区域表现不同:西南山区集约利用受细碎化影响较大,而中部江汉平原地带的空间耦合关系不强。研究结论:山区耕地应多加强耕地细碎整治,而江汉平原地带应当严格管制耕地,防止耕地弃耕抛荒现象,从而提高耕地集约利用程度。In order to explore the spatial relationship between land Province, this paper investigates spatial differentiated characteristics fragmentation and intensive use levels in Hubei of land fragmentation and intensive use levels by using spatial measurement method, gains landscape indicators of land fragmentation from the results of 2014 land use change survey in Hubei province, and discusses the correlation among different land fragmentation forms and intensive utilization degrees by using spatial autocorrelation method. The land fragmentation is opposite to the level of land intensive use. research indicates that： 1）the spatial concentration of 2）The patch area index and shape index have certain coupling relation with each index of intensive use of cultivated land, while the correlation between patch dispersion index and intensive use index is not significant. 3）The coupling relationship between land fragmentation and intensive use of cultivated land is different across the regions. The intensive use of the mountainous areas in the south-west of Hubei Province is greatly influenced by the fragmentation, while the spatial coupling is not strong in Central Jianghan Plain. In conclusion, cultivated land in mountainous areas should be prevented from fragmentation, while Jianghan Plain area should be strictly controlled to prevent cultivated land abondent, so as to improve the degree of intensive use of cultivated land.
