黄河三角洲拥有丰富的土地资源,土地总面积81万hm~2,耕地面积24.6万hm~2,待开发的宜农荒碱地40万hm~2,但因涝洼、盐碱、淡水缺乏,使巨大的开发潜力难以发挥.经过5年努力探索,终于找到了一条“挖池筑台,以台治洼,以池调水改碱”的“上农下渔”种养模式.该模式通过池塘丰蓄枯供,有效地解决了种养用水与黄河季节性断流的矛盾,是融种养和蓄水为一体的荒碱地改良新模式.
The Yellow River Delta is rich in land resources with a total land area of 810,000 hectares and a land area of 246,000 hectares and a land area of 400,000 hectares to be developed. However, due to waterlogging depression, lack of saline water and fresh water, So that a huge potential for development is difficult to play.After five years of hard exploration, finally found a “digging pool to build Taiwan to Tai Chi depression, a pool of water to Alkali” and “agriculture under the fishing” planting and breeding mode.This model by Pond abundance of dry supply, effectively solve the contradiction between planting and raising water and the Yellow River seasonal cut off, is the integration of farming and storage of water as one of the new model of improvement.
