遥感技术在长江江苏段防洪减灾中的应用

The Application of Remote Sensing Techniques to Preventing and Mitigating Flood Hazard in the Jiangsu Section of the Changjiang River

应用遥感多时相分析方法对长江岸滩变迁进行动态调查，研究河床的时空演变规律，结合河床边界条件分析及江岸崩坍灾害调查，进行江岸稳定性评价，为长江江苏段治理及防洪减灾提供基础资料和科学依据．结合长江流域生态环境变化的研究，提出长江长治久安的意见和进一步开展遥感工作的建议．

A remote sensed multi-temporal analysis was applied to monitoring the changes of banks and sandbars in the Jiangsu section of the Changjiang River.Through the research work in the law of the channel evolution, the boundary condition of the riverbed, and riverbank collapses ,combined with the data of water depth and hydrologic survey and revetment constructions, an assessment of river bank stability was made for preventing and mitigating the hazards in the Changjiang River The environmental changes ,such as deforestation, soil erosion ,and river and lake silting revealed by remote sensing were also introduced.
