聊城地区位于鲁西黄泛冲积平原,耕地面积为895万亩,其中盐碱地92万亩,占耕地面积的10.3%。本区盐碱地主要有三种类型:油碱(硫酸盐氯化物盐土)、面碱(氯化物硫酸盐盐土)、瓦碱(苏打盐土)。其分布规律是:沿河成线,靠洼成片,二坡地上多盐碱。形成这些盐碱土的原因,主要是由于地势低洼平缓,地下水位高(埋藏深度2—4
Liaocheng area is located in the Yellow River flood plain alluvial plain, arable land area of 895 mu, of which 92 mu of saline land, accounting for 10.3% of the cultivated land area. There are three main types of saline soils in the area: oil alkali (sulphate chloride salt), surface alkali (chloride sulphate salt), tile base (soda ash). Its distribution is: into the river along the line, by depression into pieces, more saline on the second slope. The reason for the formation of these saline-alkaline soils is mainly due to the gentle low-lying terrain and the high groundwater level (burial depth 2-4
