中国科学院组织的99-4航次通过在南沙渚碧礁泻湖和礁坪外同时成功地投放沉积物捕捉器,研究了渚碧礁泻湖和礁坪外碳、氮和磷的垂直转移过程.结果表明,以CaCO_3为主的碳酸盐是碳垂直转移的主要形式,而有机态的氮和磷则是泻湖和礁坪外的主要垂直转移形式,人为活动和因底层碎屑物质再悬浮而导致的稀释作用使无机磷成为珊瑚礁某些站位磷垂直转移的主要形式.生物对有机营养盐直接再利用的效率直接影响到该营养盐在珊瑚礁生态系中的转移形式,生物生产过程与动力、地貌等因素的综合作用决定了珊瑚礁泻湖内外生源要素垂直转移的形态及过程.
Chinese Academy of Sciences organized a 99-4 voyage by the Nansha Zhu Bijia Lagoon and Reef Ping at the same time successfully deposited Sediment traps to study the Zhubi reef lagoon and reef vertical carbon, nitrogen and phosphorus transfer process results show , And carbonate dominated by CaCO_3 is the main form of vertical carbon transfer. Organic nitrogen and phosphorus are the main vertical transfer forms outside the lagoon and reef, and are caused by anthropogenic activities and resuspension of the bottom detritus The dilution effect makes inorganic phosphorus the main form of vertical phosphorus transfer in some stations of coral reefs.The efficiency of biological direct reutilization of organic nutrients directly affects the nutrient transfer form in coral reef ecosystem, bio-production process and power, And other factors determine the coral reef lagoon inside and outside the vertical transfer of biological elements morphology and process.
