| 摘 要： | 综述自IPCC-AR4(联合国政府间气候变化委员会第四次评估报告)以来,华南沿海海平面变化研究的新进展,结果显示:1)7100―3500calaBP时期华南沿海的海平面较今高1.5~2.5m;2)1970―2010年的海平面上升率为2.5mm/a,高于同时期全球平均上升率2.1mm/a,原因与西太平洋暖池直接影响有关;3)采用新的全球冰川均衡调整(GIA)模型分析得出,华南沿海各验潮站的GIA效应值为-0.18~-0.30mm/a;4)实施"海平面观测与影响评价标准"(HY/T134-2010)行业推荐标准,提高了影响评估的科学性。

| Abstract: | Progress in the study of sea level changes along the coastal area of South China since IPCC-AR4 is reviewed.It is found that:1)During the period of 7100-3500cal a BP,the sea level along the area was 1.5～2.5m higher than today’s.2)From 1970 to 2010,the rise-rate of sea level was 2.5 mm/a,higher than that of the global average(2.1 mm/a)at the same period,that was related to the direct effect of the west Pacific warm pool.3)Analysis with the new GIA model shows that the GIA value is-0.18 mm/a～-0.30mm/a for the tide-gauge stations in South China.4)The scientific solidity of the evaluation is improved,as Sea Level Observation and Effects Evaluation Standards(HY/T134-2010)are implemented. |
