| 于1983年11月 - 1985年11月利用黑白瓶测氧法研究了胶州湾东南部的初级生产力及其与各环境因子的关系。结果表明，调查区内初级生产力的变化范围是0.10 - 2.82 g/(m2?d)碳，年初级生产量的平均是206 g/m2碳，夏半年（5 - 10月）的初级生产量平均占全年生产量的73.45％，浮游植物的光合作用对有效太阳辐射能的平均利用率是0.64％，初级生产力与水温、日太阳辐射能等均呈明显的正相关，胶州湾的初级生产力及其季节变化规律与其它典型的温带内湾类似。 |

| Abstract: |
| Primary production was determined by oxygen exchange method over a 25 month period (November 1983 to November, 1985) at two stations (1:120° 14.60’E, 36° 04,00’N; 2:1200 16.54’E, 36° 04.46’N) in the inlet of Jiaozhou Bay, Qingdao, China. On a seasonal basis the water column primary production varied significantly from 0.10 to 2.82 g/(m2 ? d) carbon corresponding with the winter and late summer. The annual production was 206 g/m2 carbon andcompares favourably with those from temperate coastal waters, embayments and estuaries. More than 73% of the annual primary production was contributed during the Summer-Fall months (May - October). The photosynthetic energy efficiency [% of photosynthetic active solar radiation (PAR) assimilated during photosynthesis, kcal/(m2 ? h)] was 6.64% on the average. The primary production was significantly `correlated with the PAR (r = 0.56, p < 1%, n = 25), water temperature (r = 0.56, p < 1%, n = 25), chlorophyll a concentration (r = 0.52, p < 1%, n = 25) and phosphate concentration (r = 0.55, p < 1%, n = 25). |
