在许多水生生态系统中，如水污染和赤潮，浮游植物的富营养化导致生物多样性丧失。这种现象似乎相似，但不同于通过营养相互作用（例如，捕食者-猎物系统）致富的悖论。我们在此提出了利用多重接触过程（晶格Lotka-Volterra竞争模型）诱导竞争相互作用的富集悖论。模拟结果表明，富营养化如何在竞争性生态系统中引发更多竞争，从而导致生态时间内浮游植物多样性的丧失。这一悖论在局部相互作用下得到强化，表明浮游植物的有限扩散极大地降低了种间竞争。因此，当富营养化破坏生态系统时，要么通过营养水平内种间竞争的加剧，要么通过营养相互作用的不稳定，就会出现富集悖论。除非停止人类活动造成的富营养化，否则世界水生生态系统将处于危险之中。
The biodiversity loss of phytoplankton with eutrophication has been reported in many aquatic ecosystems, e.g., water pollution and red tides. This phenomenon seems similar, but different from the paradox of enrichment via trophic interactions, e.g., predator-prey systems. We here propose the paradox of enrichment by induced competitive interactions using multiple contact process (a lattice Lotka-Volterra competition model). Simulation results demonstrate how eutrophication invokes more competitions in a competitive ecosystem resulting in the loss of phytoplankton diversity in ecological time. The paradox is enhanced under local interactions, indicating that the limited dispersal of phytoplankton reduces interspecific competition greatly. Thus, the paradox of enrichment appears when eutrophication destroys an ecosystem either by elevated interspecific competition within a trophic level and/or destabilization by trophic interactions. Unless eutrophication due to human activities is ceased, the world's aquatic ecosystems will be at risk.
