Divided field water, also known as Huanglong water belt, is 22.7 kilometers long, with huanglongdai reservoir with a total storage capacity of 94.58 million cubic meters in the middle. The rainwater collection area is 100.5 square kilometers, and the average river bed gradient is 1/46. The river originates from Jinnao (the mountain name) at the junction of Dongming and Fogang County, and its source is divided into two tributaries, both of which flow north and south. First, it originates in the northwest of the foothills, flows 4 kilometers along the city boundary in Fogang County, then enters Conghua and flows directly into the Huanglong Belt; The other originates from the southeast of the foothills and flows through Dongming, Changji and Shu Mei. Two streams meet at the end of the huanglongdai reservoir, forming water for dividing fields. After leaving huanglongdai reservoir, the river flows through the canyon between Huanglong Mountain and Huangniushan, joins the upstream flow of Liuxi River released by liuxihe reservoir, and flows to the middle and lower reaches of Liuxi River. There are Dongming District and huanglongdai reservoir Management Office in the sub-field basin, and the cultivated land is about 1.3 million mu. The population is about 9000.
