The invention discloses a black and odorous river regulating and recovering method which includes the following steps that firstly, dirt stopping and discharging of a river are performed; secondly, desilting of the river is performed; thirdly, paying-off is measured; fourthly, slope surface finishing is performed; fifthly, a plant pad is paved; sixthly, irrigation is performed; seventhly, the river is managed and maintained by manual work for one year. The black and odorous river regulating and recovering method can effectively regulates the conditions that the river is black and odorous and a water body is deteriorated, the quality of water is purified fundamentally, and a novel water body ecological system is formed. In addition, the water body can have self-growing and self-purifying capacities, and the water body can reach the standards of water of the fourth kind. Meanwhile, stability of slope bodies of the two sides of the river and conservation of water and soil are achieved, the environment is effectively renovated, after manual management and maintenance are removed, the functions of the black and odorous river regulating and recovering method can be continued, the functions of discharging dirt, preventing flood, ensuring navigation, draining flood and the like are not affected, and greening and beautifying of the urban landscape can also be effectively enhanced.
