摘　　要：对安徽省17个地市1996—2005年的耕地集约利用水平进行评价,分析其时空变化特征,为安徽省耕地资源的集约利用提供政策依据。研究结果表明:①耕地集约利用水平与耕地投入强度、利用程度和利用效益有关,其中耕地利用效益对其影响较大;②"十五"时期和"九五"时期相比,全省大部分地市耕地集约利用水平有所上升。其中,耕地投入强度有所加大,而利用程度和利用效益有所下降;③全省耕地集约利用水平空间差异显著。耕地投入水平南高北低,耕地利用程度和利用效益与之呈相反的规律,南低北高。This paper evaluated the cultivated land intensity of 17 cities in Anhui province from 1996 to 2005 and analyzed the features of the spatial-temporal in order to provide reference to cultivated land intensive use. The results indicated： 1） cultivated land utilization intensity was related to the investment degree, the utilizing intensity and benefit. It was prone to be influenced more by the benefit of cultivated land use, 2） cultivated land use intensity increased in most of cities from ＂Ninth Five Year Plan＂ period to ＂Tenth Five Year Plan＂ period, and the investment degree increased while the utilizing intensity and benefit decreased, 3） the spatial variance of the intensive use was remarkable, the investment degree reduced from south to north, while the utilizing intensity and benefit showed the opposite effects.
