中文摘要：

以重庆市南岸区2000年、2004年、2007年、2010年、2014年的Landsat TM遥感影像作为数据源,在利用Arc GIS对城镇建设用地进行提取的基础上,运用象限分析法和扩展指数分析城镇建设用地在时空上的扩展特征;建立DEA模型,利用Mat LAB计算城镇建设用地扩展的经济效益;利用一元线性回归和DEA预测2026年南岸区城镇建设用地扩展的经济效益。结果表明：2000—2014年南岸区城镇建设用地面积在空间上扩展的大小关系是：西南〉东北〉正西〉西北〉正东〉正南〉正北〉东南方向,期间面积增加1938.29hm2;2000年和2014年城镇建设用地经济效益有效,2004年、2007年和2010年城镇建设用地经济效益为无效,预测出2026年南岸区城镇建设用地经济效益有效。研究结果为南岸区和重庆市的可持续发展、城镇建设用地的合理扩展和经济效益的有效发展提供了理论基础。

英文摘要：

Taking 2000,2004,2007,2010,2014 Landsat TM of the Nan＇ an District of Chongqing City as the data source, this paper based on us- ing the AreGIS to extract the urban construction land, using the quadrant analysis method and the expansion index to analyze the urban construction land in temporal propagation characteristics, establishing the DEA model and using MatLAB to analyze the urban construction land expansion economic benefits, using the method of linear regression and DEA to predict the effective value of the economic benefit of urban construction land expansion in the Nan＇ an district in 2026. The results showed that in 2000 - 2014 period, by quadrant analysis method to realize Nan＇ an District urban construction land relationship between the magnitude of the expansion area in space was southwest 〉 northeast 〉 west 〉 northwest 〉 east 〉 south 〉 north 〉 southeast direction,urban construction land area increased 1938.29 hectares, urban construction land of 2000 and 2014 with valid values were efficient, in 2004,2007 and 2010 were invalid. It was predicted that the economic benefit of the urban construction land of the Nan＇an District in 2026 were effec- tive.The research results provided the theoretical and practical support for the sustainable development of the Nan＇ an District of Chongqing City, the rational expansion of urban construction land and the effective development of economic benefits.
