摘　　要：中国北方中生代热河生物群的生物量和生物多样性超过了同时期的其他陆地生物群,早白垩世热河生物群的辐射可能是对华北克拉通峰期破坏过程的响应,然而,克拉通破坏的深部过程和陆地生物群演化之间的内在联系尚不清楚。磷是生命所必需的营养元素,火山产物(包括熔岩和火山碎屑岩)中的磷可通过风化作用供给陆地生态系统。中国北方中生代连续的火山-沉积序列记录了火山磷供给、生物生产力和物种丰度的变化,为研究地球深部过程、火山作用与陆地生物群的协同演化提供了关键证据.火山磷供给与生物群演化之间的耦合关系表明,在华北克拉通峰期破坏期间,大量火山产物的风化作用为陆地生态系统供给了丰富的营养物质,创造了有利于热河生物群繁荣的陆地环境。与华北克拉通破坏初期相对应的侏罗纪燕辽生物群的演化也反映了上述火山-生物之间的耦合机制。The Mesozoic terrestrial Jehol Biota of northern China exceeds the biomass and biodiversity of contemporaneous Lagerstätten.From 135 to 120 Ma,biotic radiation may have responded to the peak destruction of the North China Craton.However,the direct mechanistic link between geological and biological evolution is unclear.Phosphorus(P),a bio-essential nutrient,can be supplied by weathering of volcanics in terrestrial ecosystems.The middle–late Mesozoic volcanic-sedimentary sequences of northern China are amazingly rich in terrestrial organisms.Here we demonstrate episodic increases in P delivery,biological productivity,and species abundance in these strata to reveal the coevolution of volcanism and terrestrial biotas.A massive P supply from the weathering of voluminous volcanic products of craton destruction thus supported a terrestrial environment conducive to the high prosperity of the Jehol Biota.During the nascent stage of craton destruction,such volcanic-biotic coupling can also account for the preceding Yanliao Biota with relatively fewer fossils.
