Research On Coastal Dynamic Geomorphic Evolution Along The South-western Of Laizhou Bay In The Past40Years Based On RS

With a profound impact on the Yellow River and the amount of runoff andsediment variations and human activities, Laizhou Bay West-southern coastline isundergoing significant change, the evolution of the coastline dominated by thepresence of water into the ocean’s role-based phenomena and human activities basedon multi-source information for a long time with much of remote sensing data, chartdata, terrain data as the data source, designed to shoreline change the perspective bysedimentology, time series analysis, regression analysis, and3S techniques andmethods to qualitative and quantitative analysis of the Laizhou Bay West-southerncoastline evolution studies, the establishment of40-year evolution of the coastlinescale model, not only for coastal land management, provide the basis for managementof the Yellow River Delta, but also for the Shandong Peninsula blue Economic YellowRiver Delta region as well as the implementation of efficient ecological economic zoneto provide services, the main draw the following conclusions:Evolving to Qingtuozi coastline is bounded on the evolution of the presence ofsignificant differences mode. Temporal evolution of the coastline is not synchronized,coastal landforms spatial and temporal evolution of inconsistency, Laizhou Bay in theWest Bank of the Yellow River estuary-delta changes did not result in significanteffects on the south bank of morphological evolution and the evolution of the coastline.The south bank of the West Bank and the magnitude of the spatial variation of thecoastline there is a gap bigger, there are also differences in the evolution of form. WestCoast shoreline changes are mainly affected by the evolution of the Yellow RiverEstuary, a significant change in the magnitude of the south bank of the Yellow Rivermouth coastline basically unaffected, while significantly affected by human activities,and the magnitude of the variation is much smaller than in the West Bank, the directionof migration and the West Bank, there are also differences;West and south coast of Laizhou Bay shoreline evolution has staged. West Bank:fast accretion period (1973to1983); stable period (1983-2014), with2003as theboundary Delta estuary silting regional presence. South Bank: eclipse-off period (1973to1983); rapid advance period (1983to1992); promoting stable period (1992to2014).Landform evolution and transformation, mainly evolution, net conversion direction and rate differences. Control of the West Bank by the formation and evolutionof the Yellow River delta, the landforms conversion significantly, mainly in the beachwater again for the rapid conversion of the delta plain, there is also converting tidal flatand exhausted to the sea and even the disappearance of the tidal flat; because atSouthbank in the Gulf hydrodynamic Bay Top weaker and fewer sources of sedimentalong the river brought their morphological evolution is relatively stable, mainly in theconversion tidal flats, salt plains and breeding pool.
