Water saving refers to increasing the supply of water resources by protecting and restoring natural ecosystems. Mainly includes the following three aspects:

Forest protection: Forest is an important ecosystem for water conservation. Trees and vegetation can prevent soil erosion and soil erosion, thus increasing the storage and supply of water resources. Protecting forests and maintaining forest ecosystems will help protect the quality and supply of water sources.

Reservoir construction: under the condition of tight water supply, the construction of water conservancy projects such as reservoirs can accumulate rainwater in rainy season for use in dry season. Reservoir construction needs to comprehensively consider the local climate, topography, water resources and other conditions, as well as the impact on the surrounding ecological environment.

Water resources management: Water resources management is also one of the important means to save water. Through reasonable planning and dispatching, waste and over-exploitation of water resources can be avoided. For example, by installing water-saving appliances, water meters and other measures, water waste can be reduced; At the same time, rainwater collection and utilization technology can be adopted to increase the available water resources.

In a word, saving water is a necessary means to protect people's lives and ecological environment. By taking scientific and reasonable measures to protect and restore the natural ecosystem, establish and improve the water resources management system, improve the efficiency of water resources utilization, ensure the needs of human survival and development, and make positive contributions to ecological environment protection and social sustainable development.
