政权转移通常与浅湖淹没植物的损失有关；然而，这对整个湖泊初级生产力的影响仍然知之甚少。本研究比较了两个植物群落结构不同但养分浓度相似的浅富营养化湖泊的年初级生产总值（GPP）。日GPP速率在含有沉水植物的湖泊（58623gCm（-2）年）明显高于仅浮游植物和周围植物的湖泊(40823gCm（-2）年（-1）；P
Regime shifts are commonly associated with the loss of submerged macrophytes in shallow lakes; yet, the effects of this on whole-lake primary productivity remain poorly understood. This study compares the annual gross primary production (GPP) of two shallow, eutrophic lakes with different plant community structures but similar nutrient concentrations. Daily GPP rates were substantially higher in the lake containing submerged macrophytes (58623gCm(-2)year(-1)) than in the lake featuring only phytoplankton and periphyton (40823gCm(-2)year(-1); P
