一、获得盐业遗址资料的田野工作方法与考古发现包含黄河三角洲和莱州湾的渤海南岸地区,滩涂平坦、盐碱充斥、地下卤水丰富、芦苇茂密、碱蓬丛生、淡水匮乏、旱涝灾频发、潮水倒灌、河水泛滥,虽宜于盐业生产,但非常不适合古代人们长期居住和农耕活动~([1])。与高度开发的内陆农业区相比,这里的遗址延续时间短,不同时期遗址重叠者也少,而且,古代盐业遗址保存相对较好。因此,在这里进行田野考古工作就比较容易发现遗址,也容易把握盐业遗存的分布、规模、堆积厚薄、性质及遗址群内部结构等情况。自上世纪50年代起,当地政府为开发滨海平原的土地资源,组织人员疏浚河道,修挖排水工程,排涝除碱,并修建防潮大坝,阻止海潮内侵。现在的农耕活动为挖沟取土,抬高地表,迫使咸水下流,再用淡水冲压,盐碱地通过多次洗碱后才改良为耕
First, access to information on the site of the salt industry site work methods and archaeological discoveries include the Yellow River Delta and Laizhou Bay, the Bohai Sea south coast, flat beach, saline flood, rich underground brine, reed dense, basal tufts, lack of fresh water, droughts and floods Hair, tidal intrusion, river flooding, although should be produced in the salt industry, but is not suitable for long-term living and farming activities of ancient people ~ ([1]). Compared with the highly developed inland agricultural areas, the ruins here have a short duration and few overlapping sites in different periods, and ancient salt sites are relatively well preserved. Therefore, the field archeology here is easier to find the site of the archaeological work, but also easy to grasp the distribution of the salt industry, the size, accumulation thickness, nature and internal structure of the site group. Since the 1950s, the local government has been trying to develop the land resources of the coastal plains by organizing personnel to dredge the river channels, digging and draining drainage works, draining water and removing alkali, building damp-proof dams and preventing the tidal intrusion. Current farming activities are digging ditches to borrow soil, elevating the surface of the earth, forcing the salt water to flow downwards, and then ramming it with fresh water.
