【摘要】 本文基于日本东京湾、伊势湾和浜名湖的调查资料，详细地讨论了海湾区海水中溶存甲烷的分布特征、成因及其来源。溶存甲烷在海湾中的分布主要受物理混合过程所控制；由河流携入和沉积物中产生是海湾区海水中溶存甲烷的两个主要来源。更多还原

【Abstract】 Baed on our investignted deta for Tokyo Bay. Ise Bey, and Hamana Lake in Japan. this poper discussed the dissolved methane distribution features, formation mechanism, and sources of methane in seawater of estuaries in detail. The distribution of dissolved methane in estuaries is mainly controlled by physical mixing processes . There are two principal sources for dissolved methane in seawater. One is the transportation of it by rivers and another is its production from sediment.更多还原
