摘要
///The Yellow River channel boundary and beach land use within Kaifeng City were mapped in detail by using 2007 SPOT 2.5 imagery,field surveys,and ArcGIS and ERDAS software.The river channel flood fringe lines of a typical 7-year period between 1992 and 2007 (less than 8 000 m3/s) were generated from Landsat TM images of annual largest flood peak between 1992 and 2007, in conjunction with hydrological data along the Yellow River.Additionally,the submerged Yellow River beach areas with certain regular flood flows within Kaifeng City were created overlaid with background data. Certain levels of large floods and their potential submerged areas were calculated within the Yellow River beach in Kaifeng (especially over 8 000 m3/s) based on the mathematical model of the ’downstream runoff and sediment of Yellow River’ together with data obtained from a large cross section of the river channel after 2004.According to land resource management and safety requirements for flood transit within the channel,the current issues regarding the lower Yellow River are discussed,including the increased threat of floods in low beach villages,the infrastructure of agricultural development,the living condition of farmers within this Yellow River beach area.
