Analysis on Characteristics and Trend of Shoreline Evolvement in the Yellow River Estuary

摘要

In recent years, the runoff and sand transportation of the Yellow River is declining, the corrosion of shoreline in the Yellow River Delta becomes more and more serious, and this brings up much hidden trouble for the inshore biological environment and engineering facilities. In this article, according to RS and GIS, we analyzed the multi-temporal RS image between 1987 and 2003, abstracted the spatial-temporal information of the shoreline using unsupervised classified method. Built the quantificational-relative model between the runoff and sand transportation and the corrosive area of shoreline based on data from Lijin Hydrology Station and statistical method, and did elementary forecast on the evaluative trend of the shoreline.
