摘　　要：长江经济带是全国粮食主产区,研究长江经济带耕地利用生态效率与空间格局对于保障国家粮食安全具有非常重要的现实意义。论文运用超效率SBM模型、Malmquist指数模型以及空间自相关分析等方法对长江经济带地区整体及各地级市的耕地利用生态效率进行评价并分析其区域差异特征。研究结果表明:(1)长江经济带整体生态效率平均值为0.73,在投入和产出方面的表现处于中等水平,没有达到最有效的状态,具有较大的提升空间。同时各地级市耕地利用生态效率水平大致呈现出“东低-西高”的分布格局,具有一定的区域差异性。(2)长江经济带耕地利用生态效率在空间上具有弱正自相关性,存在着集聚效应,高效率值地区辐射在带动周边地区耕地利用生态效率的提高。通过加强与邻近地区的交流与合作、提升农业生产经营管理水平、减少农业生产污染可有效提高长江经济带耕地利用生态效率。The Yangtze River Economic Zone(YREZ)is one of the main grain producing areas in China.The study of the ecological efficiency and spatial pattern of cultivated land utilization in the YREZ is of great practical significance for securing national food security.This paper used the super-efficiency SBM model,Malmquist index model and spatial autocorrelation analysis to evaluate the ecological efficiency of cultivated land use in the YREZ and in each prefecture-level city.Results revealed that:(1)The average ecological efficiency value of the YREZ was 0.73,which was at a medium level in terms of input and output.This value had not yet reached the most efficient state,with considerable room for improvement.Meanwhile,the ecological efficiency level of cultivated land use in each prefecture-level city generally showed a distribution pattern of"low in the east and high in the west",with certain regional differences.(2)The ecological efficiency of cultivated land use in the YREZ had weak positive spatial autocorrelation,and there was an agglomeration effect.Areas with high-efficiency had effects in radiating an increase in ecological efficiency of cultivated land use in surrounding areas.Through strengthening exchanges and cooperation with neighbouring areas,the ecological efficiency of cultivated land use in the YREZ could be effectively improved,via upgrading the level of agricultural production and management,and reducing the pollution of agricultural production.
