根据涠洲岛珊瑚样品资料和涠洲岛海洋站实测雨量、盐度、pH、潮位、最大波高及珊瑚普查历史资料,分析气候变化、海平面上升对涠洲岛珊瑚礁的可能影响.结果显示:1)涠洲岛的多年平均雨量为1388 mm,多年平均盐度为32.1,目前海水pH值为8.0~8.23,均在珊瑚生长合适范围内;2)用P-Ⅲ型算式得出涠洲岛的水文要素百年一遇极值为:年雨量2313 mm,最高潮位514 cm,最大波高6.1 m;3)涠洲岛珊瑚生长率(6~8 mm/a)大于海平面上升率(2.2 mm/a),涠洲岛最大潮差为450~500 cm,夏季白天遇低潮时,会增加珊瑚白化概率;4)若未来海平面上升30 cm,遇上512 cm高潮位与580 cm最大波高,不会对涠洲岛珊瑚礁造成毁灭性破坏.

@@@@Based on historical records of rainfall, salinity, PH, sea level, Max wave height and ecological surveys (Reef Check), we analyzed the effects of climate change and sea level rise on the coral reef in Weizhou Island. Our results suggest that 1) The rainfall, water salinity and PH are in the coral growth suitable range in Weizhou Island with an average annual rainfall of 1388mm, water salinity of 32.1 and PH of between 8.0 and 8.23; 2) Once-in-a-century hydrological extrema obtained from P- formulaⅢ are that, annual rainfall 2313mm, Max sea level 514cm and Max wave height 6.1m;3) the skeletal extension rate of Porites coral is 6~8mm/a, heigher than sea level rise rate (2.2mm/a) in Weizhou Island. The maximum tide range is 450~500cm, when the minimum tide occurs in the aestival daytime, coral bleaching will ascend in frequency. 4) If 512cm of maximum tide hight and 580cm of maximum wave height both occur when the sea level rise 30cm in the future, the corel reef in Weizhou Island will not be destroyed thoroughly.
