生物量无显著的时间差异，但总丰度的时间差异显著。次级生产力也存在显著的时间差异。

No apparent difference was observed in the biomass , whereas the total abundance and secondary productivity show remarkable temporal differences .

除B3站外，其它站位次级生产力都较高。

Except B3 , the secondary production of the others is very high .

整个海区100m以上水体的次级生产力平均为72.9mgC·m-2·d-1。同时计算了初级生产力与浮游动物的次级生产力的营养传递的效率，平均转化效率为18%。

The average transformation efficiency estimated from primary productivity and second productivity was 18 % .

蝗虫的次级生产力为5.18kJ／m2·a，是地上净初级生产力的0.18%。

The net production of the grasshoppers is 5.18 kJ · m - 2 · a - 1 that accounts for 0.18 % of the above ground primary production .

海区次级生产力较低的站为1号站、4号站和8号站，均少于50mgC·m-2·d-1。

The secondary productions at station 1 , 4 and 8 were low , less than 50 mgC · m ~ ( - 2 )· d ~ ( - 1 ) .

次级生产力的值为14.80g／m~2（去灰干重），明显小于驴驹河的。

The mean secondary production was 42.02g / m ~ 2 ( AFDW ) .

次级生产力的定义是异养有机体的新生物量的生产速率。

Secondary production is defined as the rate of production of new biomass by heterotrophic organisms .

浮游动物物种组成、生物量和次级生产力的变化会改变生态系统的结构和功能。

The variations of zooplankton species composition , biomass and secondary production will change the structure and function of the ecosystems .

初级生产力到浮游动物次级生产力的转化效率在9.29～69.66%之间，平均为31.31%。

The average transformation efficiency from primary production to secondary production was 31.31 % and the transformation efficiency was from 9.29 % to 69.66 % .

与历史资料比较，同安湾浮游动物的次级生产力水平比1995年的有所上升，但恢复得较慢。

Furthermore , it showed that secondary zooplankton productivity in Tongan Bay had arisen a little than that in 1995 by historical data , but it restored slower .

在河口和海岸区域，泥沙的再悬浮是一种非常重要的物理过程，再悬浮会影响水体中泥沙输运的通量、次级生产力以及污染物扩散等等。

In the estuary and coastal environment , sediment resuspension is an import process , which makes influence on the sediment mass flux , secondary productivity , pollution dispersal and so on .

五地红树林区红树植物群落类型的差异造成它们之间沉积物性质的差别，而沉积物中有机质、砂粒、粉粒含量等环境因子的差别影响了大型底栖动物的次级生产力。

The sediment characteristics were different among different mangrove communities . And the difference of the environment factors such as the concents of organic matter , sand and slit affected the the secondary productivity of the macrobenthic fauna in the mangrove wetland .

盐沼湿地的初级生产力通过潮汐涨退和生物输移运送到河口与近海生态系统，从而可能成为维持这些生态系统食物网中次级生产力的重要的能量基础。

It is a general accepted view that the primary productions of saltmarshes could delivered to the adjacent estuary and offshore ecosystem through tide dynamic an biological migration and might become main energy resource maintaining the secondary productivity of the food web in these ecosystems .
