| 摘 要： | 根据涠洲岛珊瑚礁普查(Reef Check)历史资料和涠洲岛海洋站实测海表温度(SST)历史资料,采用对比分析与相关分析方法,分析1966―2010年该岛珊瑚热白化的SST指标变化特征,结果显示:1)涠洲岛珊瑚热白化的最热周平均SST值为31.6℃或最热日平均SST值为32℃;2)1966―2010年涠洲岛的逐年最热月月均SST、最热日日均SST、年极端最高SST及最热周平均SST呈准同步变化,彼此间的相关系数为0.71~0.89,4种珊瑚热白化SST指标没有显著上升趋势;3)最热月月均SST和最热周平均SST的变化趋势与全球变暖在统计上存在显著相关关系。

| Abstract: | Based on the historical records of ecological surveys (Reef Check) and sea surface temperature (SST) from Weizhou Island Station, the variation characteristics of coral hot bleaching-SST index were studied with comparative and correlation statistical analyses. The results show that: 1) Maximum Weekly Mean (MWM) SST 31.6oC or Maximum Daily Mean (MDM) SST 32oC was the threshold temperature for local coral bleaching; 2) Synchronous variations and significant correlations (r=0.71~0.89,p<0.05) were found among M... |
