摘要：长江三峡库区是我国最重要的生态敏感区之一,受三峡水利工程和相关人类活动影响,其生态环境变化显著.揭示三峡库区生态系统结构、功能和生态过程的变化对于维护库区生态安全具有重要意义.生态环境遥感为此提供了关键途径,并在三峡库区生态环境研究中受到重视.现有的三峡库区生态环境变化遥感研究往往存在较大差异,难以有效反映生态环境变化和响应特征,加之生态本底和人类干扰活动的复杂性,三峡库区生态环境变化遥感研究仍面临诸多挑战.本文对库区环境变化遥感研究的发展阶段、研究尺度、遥感数据和方法等进行了系统总结,并从土地利用/覆盖变化、植被变化、水土安全、生态服务价值评价、生态系统健康与生态规划5个方面对库区生态环境变化遥感研究进展进行综述,在此基础上探讨了当前三峡库区生态环境变化遥感研究存在的问题,并提出未来研究中需重点关注的主要科学问题,以期为三峡库区生态环境管理和类似地区生态环境变化遥感研究提供参考.
The Three Gorges Reservoir area （TGR area）, one of the most sensitive ecological zones in China, has dramatically changes in ecosystem configurations and services driven by the Three Gorges Engineering Project and its related human activities. Thus, understanding the dynamics of ecosystem configurati ons, ecological processes and ecosystem services is an attractive and critical is- sue to promote regional ecological security of the TGR area. The remote sensing of environment is a promising approach to the target and is thus increasingly applied to and ecosystem dynamics of the TGR area on mid- and macro-scales. However, current researches often showed controversial results in ecological and environmental changes in the TGR area due to the differences in remote sensing data, scale, and land-use/cover classification. Due to the complexity of ecological configurations and human activities, challenges still exist in the remote-sensing based research of ecological and advances in remote sensing of ecological and environmental changes in the TGR area. The status, challenges and trends of ecological and environmental remote-sensing in the TGR area were further discussed and concluded in the aspect of land-use/land-cover, vegetation dynamics, soil and water security, ecosystem services, ecosystem health and its management. The remote sensing of ecological and environmental changes were proposed management of the TGR area.
