【摘要】:利用Aqua衛(wèi)星搭載的MODIS傳感器數(shù)據(jù),分析了慢速移動(dòng)的強(qiáng)臺(tái)風(fēng)"鯰魚(yú)"(Megi,2010)對(duì)中國(guó)南海北部海表面溫度(SST)、海表面葉綠素a濃度(Chl-a)、初級(jí)生產(chǎn)力(PP)和漁業(yè)資源的影響。結(jié)果顯示在研究區(qū)域內(nèi),SST平均值從臺(tái)風(fēng)前的28.8℃下降到臺(tái)風(fēng)后的25.6℃,SST最大下降5℃;Chl-a平均值從臺(tái)風(fēng)前的0.099 mg?m 3上升到0.731 mg?m 3,增長(zhǎng)6.4倍。應(yīng)用初級(jí)生產(chǎn)力垂向歸納模型反演PP,結(jié)果表明臺(tái)風(fēng)"鯰魚(yú)"極大的提高了研究區(qū)域的PP,臺(tái)風(fēng)過(guò)后8 d內(nèi)PP為1001.5 mg?(C?m2?d) 1,比2001—2009年間平均值增加684.9 mg?(C?m2?d) 1;根據(jù)臺(tái)風(fēng)后8d PP估算此次臺(tái)風(fēng)額外固碳1.01 Mt。應(yīng)用營(yíng)養(yǎng)動(dòng)態(tài)、Tait和Cushing模型估算臺(tái)風(fēng)引起的漁業(yè)資源增量為10.1×104 t。表明慢速移動(dòng)的強(qiáng)臺(tái)風(fēng)對(duì)于漁業(yè)資源生產(chǎn)量有較大影響。
[Abstract]:Based on the data of MODIS sensor carried by Aqua satellite, the concentration of chlorophyll a (Chl-a) on the sea surface temperature (SST),) in the northern South China Sea (SCS) was analyzed by slow moving typhoon "Megi,2010" (catfish) in the northern part of the South China Sea (SCS). Primary productivity (PP) and the impact of fishery resources. The results showed that in the study area, the average SST decreased from 28.8 鈩,
