摘要
珠江三角洲是我国沿海经济高速发展的地区，但因其地势低平、河网纵横、人口密集、城镇集中，成为我国未来海平面上升影响的主要脆弱区之一。本文利用ＧＬＳ技术和沿海数字高程模型，计算和编绘了在不同海平面上升情景和不同防潮设施情况下，海水可能淹没范围的专题数字图件，并给出了珠江三角洲主要市县的可能淹没面积及脆弱性分析。同时对未来海平面上升对珠江三角洲的影响和主要对策进行了初步探讨。
The economy of Pearl River Delta has developed very fast recently, but the delta is one ofthe most vulnerable areas among the Chinese coastal zones because it is vast with lowelevations,crisscross network of river courses,concentration of population,cities and towns.Inthis paper,by means of GIS technology and coastal DEM,the special data and maps of probably inundated areas by sea water have been computed and drawn for different sea一level rises andcorresponding defence-installations,and the probable inundating area and vulnerability analyses of main cities and counties in Pearl River Delta have been provided.Moreover,this paperpresents the preliminary research results of impacts of soa level rise on Pearl River Delta,and ofresponse strategies.
