东太平洋海隆热液活动区原位观测数据的小波分析和热液指标的周期性变化
Wavelet analysis of in-situ observation data and explanation on its periodicity of seafloor hydrothermal fluid, EPR

摘要: 洋中脊热液流体供养了特殊的生物群落.热液扩散流中的生物群从流体中汲取基本代谢组分(如H2S,CH4,CO2,O2等),将它们供给共生菌,通过共生菌将它们转化成机体能够利用的有机质[1-2].热液中的硫化氢一方面提供营养给化学自养菌,另一方面对许多海底生物又具有毒性[3-4],因此热液中溶解硫化氢的浓度是制约生物群空间分布和组合特征的重要因素[5-8].
