【摘要】 在我国农村人口城市化的过程中,城市建设占用大量耕地的同时,农村居民点也在占用耕地。城市化不仅包括人口城市化,还包括土地利用城市化和耕地非农化城市化。通过人口城市化指标来表征人口结构、土地利用城市化指标和耕地非农化城市化指标来表征土地利用结构。在分析江汉平原人口城市化、土地利用城市化和耕地非农化城市化空间差异的基础上,研究了江汉平原人口结构和土地利用结构的空间差异与耕地非农化空间差异之间的关系。研究发现:2004年,江汉平原地区耕地非农化面积较多的市县主要集中在武汉市城市圈内;耕地非农化主要流向城镇用地、交通用地和工矿用地,但各市县的情况不一;土地利用结构的空间差异是形成江汉平原耕地非农化空间差异的主要原因。更多还原

【Abstract】 Urbanization in China has resulted in loss of cultivated land.Based on an analysis of population urbanization,land use urbanization and dissimilarities in space of cultivated land conversion in Jianghan plain,this paper studies the relationship between the three factors,finding out the fact that cultivated land conversion in Jianghan plain is mostly occurring around the city of Wuhan,that a lot of cultivated land has been transformed into urban land,industrial land in rural area and traffic land in the cities or counties,and that dissimilarity in space of cultivated land conversion has mainly resulted from dissimilarity in space of land use structure更多还原
