受潜水、黄河过境水和潮水影响,三角洲盐渍土的区域特征是:多层位的积盐剖面;面积大而集中;空间分布呈水平动态;资源呈量变动态.除水稻之外,各种作物产量低于全省平均水平.开发利用应注意统一规划,资金统筹安排,稻田开发要适当集中,旱作物要调整结构.发展畜牧业应建立在改良草场的基础上,养殖业应限制在海岸线以内的滩地上进行. Influenced by the submersion, the Yellow River transiting water and the tidal water, the regional characteristics of the delta saline soil are: the salt accumulation profile of the multilevel position; the area is large and concentrated; the spatial distribution is horizontal and dynamic; the resource is in a variable state. Crop production is below the provincial average. Development and utilization should pay attention to a unified planning, funding arrangements, paddy field development should be properly concentrated, dry crops to adjust the structure. Development of animal husbandry should be based on improved grassland, aquaculture should be limited to Beach land within the coastline.
