摘要土地利用/覆被变化(LUCC)是全球环境变化研究的重要组成部分，同时是引起全球环境变化的重要原因和区域生态环境与气候变化的主要驱动因子。研究LUCC对于理解人与地耦合关系，分析全球气候变化特征机理、探求区域全球环境问题的原因等有着重大意义。本文以上海市为主要研究区，系统总结了近10年来国内外LUCC模型在理论、方法，利用1995年、2005年以及2015年的LANDSAT卫星遥感数据，采用监督分类中最大似然分类的方法，实现了LUCC 自动分类与精度评价；完成了上海市土地利用与覆被变化的三期遥感影像制图。在此基础上，分析了上海近20年来的LUCC时间变化与空间变化特征，探讨了引起上海市LUCC 变化的主要驱动力因子。71146

研究结果表明：（1）上海市LUCC 在时间过程上建筑用地增加了368.42%，，耕地面积减少了64，58%，林地面积增加了169.72%，水域增加了30.82%，未利用土地减少了87.46%；（2）空间上1995年到2015年建设用地总面积，平均斑块面积变小，水域面积和林地面积均增加，耕地面积和未利用地面积缩减，大量的耕地和未利用地用来发展为建筑用地以及水域和林地；（3）驱动力因素主要是自然、人文和经济三大因素。

Study on land use / Cover Change (LUCC) and its driving mechanism in Shanghai City

Abstract Land use / Cover Change (LUCC) is an important part of global environmental change research, and it is also the main cause of the global environmental change and the main driving factors of regional ecological environment and climate change. The study of LUCC is of great significance for understanding the coupling relationship between human and earth, analyzing the mechanism of global climate change and exploring the cause of regional global environmental problems. The in Shanghai as the main study area, summarizes the nearly 10 years of LUCC model at home and abroad in the theory, method, using the 1995, 2005 and 2015 Landsat satellite remote sensing data, using maximum likelihood classification of supervised classification method, the realization of the LUCC classification and accuracy assessment; completion of the Shanghai City land use and cover change on three periods of remote sensing image mapping. On the basis of this analysis, the characteristics of LUCC time and spatial variation in Shanghai in recent 20 years were analyzed, and the main driving force factors of LUCC in Shanghai city were discussed. 

The results of the study show that: (1) Shanghai LUCC in time in the process of building land increased 368.42%, cultivated land area reduced by 64, 58%, forest area increased 169.72%, waters increase the 30.82% and unused land reduced 87.46%; (2) space in 1995 to 2015 the construction of land with a total area of, average patch area small, water area and forest area increased, area of cultivated land and unused land reduced, a large number of cultivated land and use used to develop for the construction and water and forest; (3) driving force factors mainly is natural, cultural and economic factors.
