于1994年4月8－30日运用14C，15N同位素示踪法现场观测东海的初级生产力和新生产力。结果表明，初级生产力变化在200-2770mg／（m2·d）之间，高值出现于开阔深水区和近海富营养区，低值出现于近岸浑水区和外海贫营养区；东海初级生产力的主要限制因子是营养盐可得性和光照条件，在不同海区二者的作用地位有所不同。新生产力的变动范围在15－1372mg／（m2·d）山之间；剧烈的波动主要取决于氧化态、还原态氮的供给比例。f比变化在0．05－0．70。
On April 8-30, 1994, 14C and 15N isotope tracing methods were used to observe the primary productivity and new productivity of the East China Sea on the spot. The results showed that the primary productivity varied between 200-2770mg / (m2 · d), the high value appeared in the open deep water area and the coastal eutrophication area, the low value occurred in the coastal muddy water area and the outlying sea poor nutrient area; the East China Sea primary productivity The main limiting factor is the availability of nutrients and light conditions, and their roles in different sea areas are different. The range of new productivity varies between 15-1372mg / (m2 · d) mountains; the sharp fluctuations mainly depend on the oxidation state and the proportion of reduced nitrogen supply. f than the change in the 0.05-0.70.
