Therefore, to build a livable water environment in villages and towns, it is necessary to ensure the ecological circulation of water resources in villages and towns.

[0003] The site selection and plane layout of villages mostly depend on the trend of water sources. On the one hand, it is necessary to prevent flood erosion, and on the other hand, through the spatial division of the water system, settlements are formed. Therefore, the rural water ecological circulation is jointly completed by the natural water cycle and the artificial water treatment system. The natural water cycle refers to the process of natural rainfall, and through biological action or the infiltration and evaporation of surface runoff, the cycle process of re-rainfall is completed; the artificial water treatment system is the cycle process of human water intake, water conveyance, water use, and drainage. The water ecological circulation in villages and towns is a process of meeting the production and domestic water needs of villagers, and during the water cycle process, the stability of the ecosystem is also maintained.
