山东省昌邑县地处渤海湾以南,县城周围多是黄土地层,底部夹有黑土,再深即为砂土,因受渤海的影响,春、冬风力常在5～7级,阵风为8～9级。据史志记载,昌邑县早在宋代即建造邑址。历经几百年的拆建变迁压缩,沿至现今。城址土质多为风积土夹碎砖,部分为坡积土,浅则3米,深则6米左右,再深层为砂土。该土质范围东西长约2400米,南北约1500米,范围面积约360万平方米。
Changyi County in Shandong Province is located in the south of Bohai Bay. There are many layers of yellow earth around the county seat, with black soil at the bottom and deep sand. Due to the influence of the Bohai Sea, the spring and winter wind power is often between 5 and 7 and the gust is 8 to 9 levels. According to historical records, Changyi County was built as early as the Song Dynasty. After hundreds of years of demolition and construction changes, it has been reduced to the present day. Most of the soil at the site is eolian soil, and some of them are slope soils, which are 3 meters shallow and 6 meters deep, and then the deep layer is sandy soil. The soil range is approximately 2400 meters long from east to west, approximately 1,500 meters from north to south, and has a total area of approximately 3.6 million square meters.
