【摘要】：大型底栖动物是海洋生态系统的重要组成部分,在生态系统物流和能流中占有重要地位。定量估算海洋大型底栖动物次级生产力在其功能研究中具有重要意义。本文综述了海洋大型底栖动物次级生产力估算模型研究的3个阶段:起步阶段(1979-1990)、发展与完善(1990-2001)、成熟并广泛应用(2001-至今)。国内关于海洋大型底栖动物次级生产力估算基本都采用Brey(1990)经验公式,采用经验公式的方式可分为3类:逐种计算、按站位计算和按类群计算,逐种和按类群计算最符合Brey(1990)给出的参考步骤。不同方法估算同一海域次级生产力结果不同,同一估算方法估算不同生境不同群落次级生产力结果偏差也不同。今后的工作应注重种群次级生产力研究,积累大量基础数据,以便建立适宜我国特定海域的大型底栖动物次级生产力估算模型。
[Abstract]:Macrobenthos are an important part of marine ecosystem and play an important role in ecosystem logistics and energy flow. Quantitative estimation of secondary productivity of marine macrobenthos is of great significance in the study of its function. In this paper, three stages of the estimation model of secondary productivity of marine macrobenthos are reviewed: the initial stage (197 ~ 1990), the development and perfection (1990 ~ 2001), and the maturity and wide application (2001-present). Brey (1990) empirical formula is used to estimate the secondary productivity of marine macrobenthos in China. The empirical formula can be divided into three categories: one by one, by station and by group. The calculation of species by species and by group is most in accordance with the reference steps given by Brey (1990). The results of different methods to estimate the secondary productivity in the same sea area are different, and the deviation of the results of the same estimation method to estimate the secondary productivity of different communities in different habitats is also different. In the future, attention should be paid to the study of secondary productivity of populations and a large number of basic data should be accumulated in order to establish an estimation model of secondary productivity of macrobenthos suitable for specific sea areas in China.
