Geografía
Curso del río
El río Anning nace en la cordillera Xiaoxiang meridional, en el condado de Mianning , provincia de Liangshan. Desde allí, fluye hacia el sur entre las montañas Daxue meridionales y la cordillera Xiaoxiang, atravesando la llanura del río Anning, y se une a su afluente izquierdo más grande, el río Sunshui , en Luguzhen . Desde su nacimiento, el Sunshui constituye el cauce principal del Anning. Siguiendo hacia el sur, la llanura del río Anning se ensancha, propiciando una mayor actividad humana. La capital de Liangshan, Xichang , se encuentra en la parte más ancha del valle, al este del río. [ 2 ]
El río Anning nace en la llanura fluvial del mismo nombre, en el condado de Dechang , y fluye hacia el sur-suroeste hasta unirse al río Yalong en el condado de Yanbian , en Panzhihua. La longitud total del río es de 320 km (200 millas) .
Llanura del río Anning
Unlike other larger river valleys in the region, including those of the deeply-incised Yalong and Jinsha Rivers, the Anning River has a relatively flat valley known as the Anning River Plain (Chinese:安宁河谷平原).[3] For the 125 km (78 mi) section of river between Mianning and Dechang, the valley stretches between 4 km (2.5 mi) and 10 km (6.2 mi) wide. The Anning River Plain is the largest valley plain in southwest Sichuan with an area of 1,800 km2 (690 mi2) and its fertile soils support a variety of agricultural activities. The plain, and in fact the entire Anning River's course, follows the tectonically active Anninghe Fault where a southeastern portion of the Tibetan Plateau abuts the Yangtze Plate.[2]Qiong Lake is found on the eastern edge of the Anning River Plain, approximately 10 km (6.2 mi) from the Anning River.
History
There is evidence of human activity in the Anning River basin since the Neolithic Age.[4] Burial tombs from this era have been uncovered. In the last 3,000 years, the Anning River basin developed as the heartland for the Yi People who migrated from the Tibetan Plateau and supplanted or assimilated with the original inhabitants. In the 2nd century BCE, the Anning River basin was incorporated into Han dynasty China as it provided a crucial direct route between the Sichuan Basin and the annexedDian kingdom in present-day Yunnan. Qiongdu (now known as Xichang) was the primary settlement in the region and was a territorial garrison of the Han. The Anning River valley drifted in and out of Chinese administration through subsequent dynasties until its control by the Chinese was solidified in the Ming dynasty.
In addition to being a major source of agriculture for the region, the Anning River and its valley has served as a major transportation corridor in southwest China, particularly between the major cities of Kunming and Chengdu. The Chengdu–Kunming railway, completed in 1970, and the G5 Expressway, completed in 2018, both follow the course of the Anning River.[3]
Several dams have been constructed along the Anning River's length, including the Chengnan Dam, Qianjinqu Dam, and Xiaosanxia Dam.
