次级生产

传统上认为红树林输出的有机质产生巨大的能流，支持了巨大的河口和近岸水域生态系统的次级生产。

A central view of tropical estuarine ecology is that export of organic matter from mangroves represents a major energy pathway and support much of the secondary production of estuaries and nearshore waters .

次级生产能量转化效率较高（3.92%）；

The gross efficiency of conversion of animal products was higher ( 3.92 % ) .

与渤海和南黄海大型底栖动物的丰度和生物量比较，丰度和生物量均低于这两个海域，但是胶州湾大型底栖动物的总次级生产量高于渤海。

Compared with the studies on macrofauna in the Bohai Sea and southern Yellow Sea , the macrobenthic abundance and biomass in the Jiaozhou Bay were lower .

结果表明，该地区养羊牧业生态系统中初级生产中光能利用率为0.13%，次级生产中饲料转化率为2.7%，都属于偏低水平。

The results show that the utilization rate of solar energy is 0 . 13 % in the section of primary production and ratio of second production is 2 . 7 % .

次级生产饲料能、氮和磷的转化率分别为11.02%，19.19%和15.62%，由初级产品干物质转化为动物蛋白质的效率为2.58%。

The efficiency of conversion of seed energy , nitrogen and phosphorus of the livestock subsystem was 11.02 % , 19.19 % and 15.62 % , respectively , and the efficiency of conversion from dry matter of primary product to animal protein was 2.58 % .
