底栖动物次级生产力研究的理论与方法

摘要

Zoobenthos are one of the major ecological groups in fresh waters. They play an important role in nutrient cycling and energy flow in ecosystems, and are very useful food resources for fish. Zoobenthos are also used as biological monitors of the environmental health of lakes and rivers. Theories and methods of the secondary production of zoobenthos were reviewed with emphasis on the calculation of secondary production, P/B coefficient and factors to affect secondary production. In addition, this paper also presents new advances including modelling of the secondary production and construction of benthic food web.%底栖动物是淡水生态系统的一个主要组成部分，在渔业和环境科学上均有重要的理论意义和广泛的应用前景本文综述了国外在底栖动物次级生产力研究中的理论和方法，重点阐述了底栖动物次级生产力的计算方法、P/B系数、生产量以及影响次级生产力的因素，并总结了目前该领域的一些新进展，以期为国内相关研究提供参考和借鉴。
