摘要
滩涂围垦、水产养殖、防波堤建设和航道疏浚等往往涉及潮滩冲淤变化的研究。冲淤变化是一种复杂的物理过程,它包括许多自然因素和人类诱发因素。该文使用MSS、TM、ETM及SPOT四类数据源,共计24个时相,时间跨度为1976—2002年,利用多时相卫星遥感图像水边线高程反演技术,确定了温州地区不同部位淤泥质潮滩岸线的变化,计算不同部位潮滩坡度及淤积、侵蚀速度,为温州地区潮滩的开发建设提供了理论依据。
The problems of beach dynamical physiognomy are usually related with beach inning, aquiculture, jetty construction, and sea - route dredging and so on. The deposition and erosion of tidal flat is one of the important fields in those problems. The change of deposition and erosion is a complicated physical processing. It includes many natural factors and human being factors. This paper applied data resources such as MSS, TM, ETM and SPOT, which amount to 24 time series and span from 1976 to 2002. It determined the shoreline variation of Wenzhou tidal flats at different locations, and calculated velocity of deposition, by applying waterside line elevation inversion technology based on multi - temporal satellite remote sensing images. The research conclusion built the theoretical foundation for the development of tidal flat at Wenzhou area.
