摘　　要：硅是地壳中的第二大组成元素,且作为水生态系统中重要的营养元素,在全球气候变化及地表物质循环中发挥着关键作用。硅在海洋中以产生可溶性硅的形式进行循环,而溶解硅(DSi)产生的方式主要是通过生物硅(BSi)的溶解和成岩硅(LSi)的风化,这对海洋生态系统起到重要作用。因此,了解海洋中的硅循环对于理解更广泛的问题(如海洋生物泵的碳固存)至关重要。Silicon is the second largest element in the earth's crust,and as an important nutrient element in aquatic ecosystem,it plays a key role in global climate change and surface material cycle.Silicon circulates in the ocean in the form of soluble silicon(DSi),which is mainly produced through the dissolution of biogenic silicon(BSi)and weathering of diagenetic silicon(LSi),which plays an important role in the marine ecosystem.Therefore,understanding the silicon cycle in the ocean is crucial for understanding broader issues such as carbon sequestration in marine bio-pumps.

关 键 词：海洋生态系统 硅循环 溶解硅 生物硅
