A river/lake/stream sediment carbonized ceramsite, having a sealed micro-pore structure and a bulk density of 300-400 kg/m3. The river/lake/stream sediment carbonized ceramsite is prepared from river/lake/stream sediment cakes and a swelling agent, or is prepared from the river/lake/stream sediment cakes, a desiccant and the swelling agent. The weight percentage ratio of the swelling agent is 1-2% on the basis that the total weight of raw materials of the river/lake/stream sediment carbonized ceramsite is 100%.
