利用ZooScan图像扫描技术, 建立胶州湾浮游动物优势种中华哲水蚤和强壮箭虫体长、面积和体积与干重之间的回归关系。比较了不同季节、不同参数之间的差异。结果表明, 不同月份的回归关系之间无显著差异, 在三个体型参数中, 面积拟合生物量的程度最好, 是利用图像方法估算生物量最佳参数。中华哲水蚤和强壮箭虫体型-生物量转换关系可以分别表示为: lgDW=1.61lgA+ 1.69, lgDW=1.54lgA+1.32。 |

Abstract: |
This study estimates regressions between shape parameters that contained length, area and volume were obtained from image scanned by ZooScan, and dry weight with dominant zooplankton of Calanus sinicus and Sagitta crassa in Jiaozhou Bay. This study intends to reveal the differences of regressions established by various parameters in several seasons. The results show that there are no significant difference in regressions of different months and area, which is recommended as the optimum parameter in image method. The regressions of shape parameter-biomass of C. sinicus and S. crassa are: lgDW=1.61lgA+1.69, lgDW=1.54lgA+1.32. |
