Check whether the water quality is normal, whether the river bank is built randomly, and whether the domestic sewage is directly discharged... This is the routine work of He Qiyin when he patrols the river every week. He Qiyin is the secretary of the Party branch of Changjiang Village, Panjiang Town, Guiding County, Qiannan Buyei and Miao Autonomous Prefecture, Guizhou Province, and also a village head of the Jiashubao section of the Luobei River under the Wujiang River system. In his free time, he always opens the "River Captain App" on his phone, clicks "Start River Patrol", and walks along the river bank to record. The river section I am responsible for is 1.5 kilometers long, and I walk at least once a week to handle any problems on site. If problems cannot be solved on site, they will be registered and tracked for improvement one by one. "He Qiyin said that since the beginning of this year, he has patrolled the river nearly 30 times, with a total distance of over 40 kilometers. The water environment of the Jiashubao section is generally maintained in good condition. In Guizhou, there are over 20000 rivers like He Qiyin. As an important ecological barrier in the upper reaches of the Yangtze River and the Pearl River and one of the first batch of national ecological civilization pilot areas, Guizhou took the lead in building a five level river length system covering provinces, cities, counties, townships and villages in 2017. There are 22755 rivers (lakes) in 4697 rivers (lakes) in the province. Every river that the common people can name is under the responsibility of the river chief, "said Yang Song, the person in charge of the river and lake chief system workstation in Qianxi City, Guizhou Province. River governance involves a wide range of problems, and since the implementation of the river chief system, all levels have compacted the responsibility for river protection, changing the" Nine Dragons Water Control "state and forming a work pattern of joint management. Ma Lu River is one of the municipal rivers in Bijie City. For a period of time, due to the influence of coastal coal mine wastewater, urban domestic sewage, agricultural non-point source pollution, etc., the quality of the river water on the roads gradually deteriorated, and some places appeared black and odorous water bodies. After the implementation of the river chief system, Bijie formed a "five level river chief" relay linkage. The road and river management followed the "four single joint handling" model of "placing orders" by the river chief, "receiving orders" by the responsible unit, "handling orders" by the street and township, and "supervising orders" by the assessment department. The existing problems were eliminated and rectified one by one, achieving a steady improvement in water quality. Yang Song introduced that the river chief system has promoted the formation of a river and lake management work pattern with party and government responsibility, departmental coordination, and implementation at each level. Especially with the introduction of a series of related supporting policies, we have further compacted our responsibilities and promoted the "long-term governance" of the river. Huawu Village, Xinren Miao Township, Qianxi City, was built along Liuchong River, the first tributary of Wujiang River. In the past, cage fish farming in the village once polluted Liuchong River. In 2017, Qianxi City strengthened the environmental control of Liuchong River. "Under the leadership of the river chief of Huawu Village of Liuchong River, nearly 50 cages were removed and more than 40 fishing boats landed in Huawu Village." Wang Xijin, director of Qianxi Water and Soil Conservation Monitoring Center, introduced that in order to harness Liuchong River, the local government has formulated a "one river, one policy" plan, and promoted the rectification of problems according to the inverted schedule of the list of problems. "The river leader system is an effective measure to solve complex water problems and maintain the health of rivers and lakes." Wang Xijin said that the removal of cages and the prohibition of fishing are only a small part of Liuchong River governance, and water quality monitoring, shoreline protection, water ecological restoration and other work should be implemented. Ai Xing, a village cadre in Huawu Village, introduced that Huawu Village insisted on shore treatment of water problems, improved Forest cover by implementing slope to ladder and Grain for Green, built more than 110 domestic sewage treatment facilities, and developed
