摘要
在长江三峡库区移民工程中 ,我们采用 ETM+、SPOT、IKONOS等多源、多时相、多分辨率航天、航空遥感数据组合 ,监测移民工程的动态变化 ,通过对库区奉节 -巴东段移民搬迁建与安置、新开发用地分布、土地利用与土地结构变化、地质灾害及衍生地质灾害与防治、库区环境及生态平衡与改善经济结构以及移民工程遥感动态监测等 ,取得突破性进展 ,获取了一批重要成果。为三峡移民工程进一步全面、安全地实施、改进规划管理工作及库区经济可持续发展 ,提供了科学依据和决策性建议。
Having made the most of '3S' advantages, it is the first time during the construction of Three Gorges Project to monitor the dynamic changes of settlement along the Three Gorges Reservoir area of the Yangtze River by utilizing the combination of space and aerial borne data such as ETM+, SPOT, IKONOS with characteristics of multi-data, multi-temporal and multi-resolution. In addition, through the project of dynamic monitoring on settlement in the Three Gorges Reservoir area ( Fengjie-Badong), great strides towards the movements and settlement of population, distribution of newly-developed land, change of land use and land structure, prevention of geological hazard including its derived geological hazard, protection of environment and ecology as well as improvement of economic structure in the area have been made, indeed. Also,many basic data and achievements of scientific research have been collected and attained due to the construction of this project. Particularly, it can be regarded as the first achievement attained during the application of remote sensing technology using the high resolution satellite and aerial borne data received from those satellites of the latest generation launched in 1999. The outcome of research can provide an assistance while the final decision is to be made scientifically in terms of implementation of settlement planning, administration and sustainable development of the Three Gorges Reservoir area. Based on such a practice, it shows that the application of remote sensing in dynamic monitoring settlement is of success in the project. It can be regarded as a technology that is updated and accurate as well.
