? Beijing is the ancient capital of the Six Dynasties, and there are moats around Jinzhong and Yuanda. Today, Tuchenggou outside Deshengmen is the Yuandadu.
The remains of the moat in Beijing. 1368 (the first year of Hongwu in Ming Dynasty), after the Ming army captured the Yuan Dynasty, it moved the north wall of the Yuan Dynasty to the south in 137 1 year, with Gaoliang River and Jishuitan (a part of Taiping Lake) as the north moat. 14 19, the south wall of the Yuan Dynasty moved south and a new moat was dug (the first three moats). As for the east moat and the west moat of the Yuan Dynasty, they were still in accordance with the old system of the Yuan Dynasty, but only extended to the south and connected with the first three moats respectively. After that, when the outer wall was built, the outer city moat (now the south moat) was excavated, and the water of each moat was collected at Dongbianmen, passed through Datong Bridge and entered Tonghui River. From then on, a moat pattern matching the wall of Beijing was formed, and in the following 500 years, it gradually became an important symbol of the old Beijing city.
According to the calculation in 1953, the total length of the moat in Beijing is 4 1. 19 km. Among them, the northwest Huhe (from Songlinmen to Xizhimen) is 1.84 km long, the northeast moat (from Songlinmen to Dongbianmen) is 10.9 1 km long, the west moat (from Xizhimen to Xibianmen) is 5.22 km long, and the first three moats (from Xibianmen to Dongbianmen) are 7. Before the founding of the People's Republic of China, the water source of Beijing moat mainly came from Yuquan Mountain and Xishan Spring, which flowed into the moat through the long river and Yuyuantan, and then into the urban rivers and lakes through the moat. Beijing moat is also a drainage channel for urban rainwater and domestic water, which has played a great role in flood control and drainage in Beijing in history.
? At present, there is only a section of the northern moat and the southern moat in the outer city in Beijing, with a total length of only half of the original.
? It is said that Beijing is expensive in the west and rich in the east. From historical research, it is better to look at the moat. At present, the city scenes of Fuchengmen's Financial Street, Dongzhimen to Yonghe Palace and Andingmen's East Moat are incomparable with those of Xuanwu Caishikou and Chongwen Jingtai Bridge. One hour at noon today, I went to the cultural news of the Ministry of Culture and others. The scenery around the moat is the deepest.
