Management of waterlogged area based on a three-dimensional agricultural model of ponds and dry land

The development of underground engineering caused a large area of waterlogged area, resulting in damage to farmland and inability to cultivate. An innovative three-dimensional agricultural management strategy was proposed in this study to enhance land management in the affected regions. Three-dimensional models are based on the root characteristics of different crops, and these models are often used to guide planting in the waterlogged area. This strategy combined deep digging and shallow padding techniques, integrating soil management and paddy field coordination to advance modern agriculture. Changes in the area of waterlogging were estimated for various diving levels using field measurements and simulation analysis. The results of the numerical simulation for the area of waterlogging were used to assess the viability of the three-dimensional agricultural model, which included detailed dynamic soil volume changes and groundwater level variations. Furthermore, various crop combinations were examined to determine their rationality within this multilayered agricultural system. The results indicated that the most cost-effective and practical approach involved planting corn in the upper layer, planting lotus roots in the middle layer, and cultivating loaches in the lower layer. This multitiered strategy significantly accelerated the restoration of waterlogged area, offering a more sustainable approach for agricultural practices in challenging environments. The research results are also of great significance for the prevention and control of surface waterlogged area in underground engineering in reclaimed land zones.
