| 摘 要： | 潮滩是淤泥质海岸最主要的地貌类型之一,淤泥质潮滩特征在很大程度上代表了所在海岸带的性质,查清其性质和分布对于合理开发潮滩资源和研究现代海岸带动态变化具有重要意义.本文以星载多源遥感技术为主要研究手段,结合常规调查资料和野外调查工作,以长江口崇明东滩为研究区,利用淤泥质潮滩水边线提取技术和潮位站实测水位高程进行潮滩地形反演,确定潮滩坡度及其淤积或侵蚀速度,为长江口潮滩资源合理开发利用和环境保护的长远规划提供重要的参考依据.

| Abstract: | The tidal flat is one of the silt coast geography types.Understanding its characteristics and distributions clearly is important for developing tidal flat resources and researching tidal flat dynamical variety.The Chongming east tidal flat in the Changjiang Estuary was taken as research areas.The gradient and velocity of deposition or erosion are calculated by applying waterside line elevation inversion technology based on multi temporal satellite remote sensing images and field investigation data.The resul... |
