江苏省里下河地区水网沼泽地带经人工堆叠形成了一种高出水面的台田，当地称为垛田。垛田土壤物质来源主要为长期黄淮冲积形成的湖积物质，土壤的理化性质已不同于堆叠前的河泥，在利用上主要按照基塘理论实行农林复合农作制，才有利于垛田土壤生产力的持续发展。
Jiangsu Province, the Lixiahe water network marsh by artificial stacking to form a surface above the water table, locally known as the piled field. The main source of soil material in the piled field is the lacustrine sediments formed by the long-term Huanghuai alluvial sediment. The physical and chemical properties of the soil are different from the river mud before stacking. Sustainable development of soil productivity.
