黄河三角周地区,是我们的母亲河黄河携带大量泥沙填海造陆形成。它形成的时间大约150多年。所以黄河三角洲是一个非常年轻的土地。根据对其地质情况的勘探,包括:1、现代河流冲积层,主要构成:砂壤土,颗粒均匀,粘性小,含水量大;粉细砂,土质不均匀,局部杂砂壤土。2、海陆交互相沉积层,主要构成:粉细砂,土质不均匀,局部杂砂壤 The Yellow River Delta region, is our mother River Yellow River carrying a large amount of sediment reclamation land formation. It formed about 150 years ago. So the Yellow River Delta is a very young land. According to the exploration of its geological conditions, including: 1, modern river alluvium, the main components: sandy loam, uniform particles, viscous, water content; fine sand, uneven soil, local Zaosha soil. 2, sea and land interaction phase sedimentary layer, the main components: fine sand, uneven soil quality, local zaosi
