| 摘 要： | 于１９８８－１９９１年，对长江三角洲附近沿海潮滩和湿地进行较全面的调查，利用高程－面积法、沉积速率法，并引进未来冲淤趋势参数，对全区１４个典型潮滩断面进行海平面上升影响的估算。结果表明，当海平面上升０．５ｍ和１．０ｍ时，全区潮滩面积分别比１９９０年的减少９．２％和１６．７％；湿地面积减少２０％和２８％，并发生高级类型向低级类型的逆向演替。各岸段损失率相差悬殊，以侵岸段较大，淤涨岸段将减缓淤涨，甚至

| Abstract: | A comprehensive investigation on the tidal flat and coastal wetland in the Changjiang River Delta and its adjacent area was conducted from 1988-1991 for studying the impact of sea level rise. The elevation-area, sedimentation rate and parameter estimate of future scourage-siltation tendency are used to calculate the impacts of sea level rise in 14 typical cross sections of the tidal flat. The result shows that if sea level rises by 50 and 100 cm, the area of tidal flat will decrease by 9.2% and 16.7% respectively of that in 1990 and the areas of coastal wetland decrease by 20% and 28% respectively. At the same time, wetlands will also retro-gress from advanced forms to original ones. Judged by the whole area, the damage rates vary in the different coastal section, and are high in the erosion coasts and low in the accretion coasts. Sea level rise will result in reduction in sedimentation rate or even turn accretion into erosion. |
