摘　　要：提升土地利用效益是当前建设"美丽国土"和全面建成小康社会的必然要求。从社会、经济、生态和环境四个准则层出发构建岳阳市土地利用效益评价指标体系。运用熵权TOPSIS法和障碍度模型,利用2001—2010年岳阳市土地利用效益相关数据,对岳阳市土地利用效益及其障碍度进行分析。经分析显示:2001—2010年岳阳市土地利用效益在上下浮动中表现出较强的上升趋势,研究时间段后期年增长速度显著加快。岳阳市土地利用效益走过了较差(2001—2002年)、中等(2003—2007年)和良好(2008—2010年)3个阶段,其中中等阶段(2003—2007年)经历时间最长。总体来说,经济效益和生态效益对岳阳市土地利用效益的影响程度比较大,2010年以前地均财政收入是降低岳阳市土地利用效益的最大障碍因子,2010年造林面积则跃升为首要障碍因子。Improving the efficiency of land use is a mandatory requirement for building ＂Beautiful land＂ and a all-round well-off society way, For the sake of evaluating the land use efficiency in Yueyang, index system has been established from four layers：social benefit, economic benefit, ecological benefit and environmental benefit. Based on the data of land use efficiency during 2001 - 2010 ,this paper analyzed the land use efficiency and the obstacles of land use in Yueyang with the entropy TOPSIS method and obstacle degree model. The result of study showed that： the land use efficiency of Yueyang fl＇om 2001 to 2010 demonstrates a strong escalating trend. The average annual growth rate has reached nearly 6.71% , and the growth rate accelerated significantly in the late stage. From 2001 to 2010, the land use efficiency of Yueyang could be divided into 3 stages. In the first stage （2001 -2002）, the efficiency was pretty low. In the second stage （2003 -2007）, the efficiency was medium, but this stage last longest. In the third stage （2008 -2010）, the efficiency was the highest. Comprehensively speaking, the econom- ic benefit and ecological benefit bad a significant impact on the land use efficiency of Yueyang, and before the year of 2010, the average finan- cial income was the most important factor for the land use efficiency of Yueyang, but the planting area became the primary factor in 2010.
