摘要: 对长江口海平面上升动态及其对沿海潮汐特性的影响进行了简析。结合长江口崇明三岛地区除涝安全面临海平面上升的影响和威胁,分别建立了基于海平面上升的上海市崇明三岛水系一维平原感潮河网水动力模型,深入开展了海平面上升对三岛地区除涝安全影响的模拟研究。结果显示,至2030年,长江口海平面上升10~16 cm,崇明三岛片区的面平均除涝最高水位、局部除涝最高水位均呈上升趋势,其中,崇明岛片受影响最大,对应水位将分别上升3~5 cm、4~6 cm;长兴岛片受影响次之,对应水位将分别上升3~4 cm、3~5 cm;横沙岛片受影响相对最小,对应水位均将上升1~2 cm;长江口海平面上升对崇明三岛的除涝安全影响在可控范围内。

Abstract: The dynamic state of sea level rise in the Changjiang Estuary and its impacts on tidal characteristics were summarized and analyzed. Then three series of 1-D river-net tidal hydraulic model based on sea level rising in the Changjiang Estuary, respectively for Chongming island, Changxing island and Hengsha island in Chongming county, were established. Thereafter impacts of waterlogging-controlling safety on Chongming county under sea level rise were studied respectively and deeply. Up to the year of 2030, when the sea level may rise up by 10-16 cm in the Changjiang Estuary, both of the mean regional waterlogging-controlling highest water level and the mean local highest water level within Chongming county will present uprising situation. The impact on Chongming island is the most, the two above mentioned water levels will rise up by 3-5 cm and 4-6 cm respectively; for Changxing island, its impact is minor, the water levels will rise up by 3-4 cm and 3-5 cm respectively; for Hengsha island, its impaction is the least, both water level will rise up by 1-2 cm and 1-2 cm respectively; but all impacts due to sea level rise on Chongming county?waterlogging-controlling safety will be under control.

Key words: Chongming county, sea level rise, waterlogging-controlling safety, 1-D river-net hydraulic model
