Abstract Food webs capture the trophic relationships and energy fluxes between species, which has fundamental impacts on ecosystem functioning stability. Within a food web, flux distribution predator its prey species is shaped by quantity–quality trade‐offs contiguity of foraging. But among as well drivers implications remain unclear. Here we used 157 aquatic webs, contain explicit information, to examine whether predator's foraging asymmetric biased towards lower or higher levels, how these...
为揭示农户个体行为与流域农业非点源营养盐产生和控制政策之间的逻辑关系，以珠江流域为研究对象，采用系统动力学模型与多主体农户和农村环境管理模型耦合构建流域营养盐污染控制政策的情景分析方法，基于农户在化肥税和农药税组合型政策下的生产行为设计了基准情景、低化肥税情景、中化肥税情景和高化肥税情景4种具有代表性的情景方案，并在各种情景下定量描述流域营养盐对农业政策的响应和评估流域营养盐控制的优选政策方案.结果显示：从农业投入和产出的角度看，2030年低化肥税情景、中化肥税情景和高化肥税情景的化肥施用量相对基准情景分别减少了24.0%、39.8%和50.2%，农药使用量分别减少了27.6%、32.8%和37.4%，农作物产量分别减少了10.0%、16.3%和21.2%，畜禽养殖量分别增加了5.9%、7.5%和14.0%；2030年，基准情景、低化肥税情景、中化肥税情景和高化肥税情景的总氮入河量分别达到94.5、85.1、78.5和75.3万t，总磷入河量分别达到14.0、12.8、12.0和11.6万t；化肥税和农药税的组合型政策能够有效减少营养盐污染量，然而，中化肥税情景和高化肥税情景比低...
