稻田生物群落的能流参数

为了从能流动态来研究稻田生物群落,本文用田间调查和实验室测定等方法,取得了晚稻田生物群落的物种数量、生物量、热值、呼吸量、生产力、同化效率、摄食量等数据。据此,进一步估算了晚稻田生物群落的能量流动参数。根据其能量收支,用能量金字塔总结了晚稻田生物群落各类种群间的能量关系。

Parameters of energy flow in paddy field community

In this paper, communities in paddy field were studied on the basis of combination of field survey with laboratory analysis from the view point of dynamics of energy flow. Data of species number, biomass, heat value, respiration loss, productivity, assimilation efficiency and ingestion of communities in late rice field were obtained. According to above data, parameters of energy flow of communities in late rice field were evaluated.
