中文摘要：

以2007年和2013年两期ETM＋影像,并结合相关辅助信息,进行长沙市市区的土地利用空间格局变化研究。采用动态度、土地利用转移矩阵等方法,揭示了长沙市城镇区域生态环境格局特点与土地利用变化的过程,并对所研究的驱动力进行分析和探讨。结果表明：耕地的减少和建设用地的增加是长沙市区土地利用变化的总体特征;矿产资源的分布影响长沙城市用地格局,城市建设用地扩展空间异性逐步增强;长沙市区土地利用格局和环境生态变迁的演化是由其自身的自然条件、生态环境变化、矿产资源分布、城市道路规划、经济因素限制等多种因素综合作用的结果。

英文摘要：

In this study, ETM＋ images of 2007 and 2013 and relevant ancillary data were used to monitor land use pattern change of Changsha. With methods such as the dynamic degree and land use transition matrix, the paper revealed the characteristics of regional ecological environmental pattern and the process of land use change in Changsha, and analyzed and discussed the driving forces. The results showed that the increase of construction land and the decrease of arable land was the main characteristic of land use change of Changsha. The distribution of mineral resources affected urban land use pattern of Changsha, and the expansion anisotropy of construction land gradually increased; the evolution of land use pattern and environmental ecological shift of Changsha was the combination results of natural conditions, ecological environmental change, mineral resource distribution, urban road planning, economic factor limitation, etc.
