How water use can be sustained

Here's how to achieve sustainable use of water resources:

1. Vigorously develop greening and increase forest area to conserve water sources. Forests have the functions of conserving water sources, reducing ineffective evaporation and regulating microclimate, which has the significance of reducing water. It is of open source significance that forest areas and forest margins have the potential to increase precipitation.

2. Improve the comprehensive utilization of water resources, and water has the characteristics of comprehensive utilization in the same space. The reservoir can store floodwater, and can also breed aquatic animals and plants, the large water surface can be navigable, and some water bodies can also be opened up for tourism. The water used for hydroelectric power generation can be used for irrigation.

3. Urban development and utilization of sewage resources, development of water treatment, sewage reuse technology. After being treated and purified, the high-quality miscellaneous waste water generated by some industrial production and life in the city can reach a certain water quality standard, and can be used as non-potable water for greening, sanitation and other aspects.

4. Develop and promote water-saving appliances. According to incomplete statistics, China currently has nearly 40 million sets of toilet water tanks and a large number of other sanitary appliances, and hundreds of millions of cubic meters of water are lost every year due to toilet tank leakage.

Introduction to the sustainable use of water resources:

In order to ensure the sustainable development of human society, economy and living environment, the principle of sustainable use of water resources is implemented. The idea of sustainable development was put forward in the 80s of the 20th century in the search for a way out of the contradiction between environment and development, and the issue of sustainable use was raised accordingly in the field of renewable natural resources.

The basic idea is to pay attention to the balance between the environmental detriment caused by the development and the expected social benefits in the development of natural resources.

In the development and utilization of water resources, in order to maintain this balance, the principle of protecting the productivity of water sources and land for drinking, the principle of protecting biodiversity from disturbance or the balanced development of ecosystems, and the principle of not overexploiting and polluting renewable freshwater resources should be observed.

Therefore, in the development and utilization of water resources, the life support systems and ecosystems on the earth must not be harmed, and the water resources required for sustainable social and economic development must be guaranteed, and the water requirements of all walks of life must be met and the water supply must be sustained.

The rational development and utilization of <> water resources includes the scientific dispatch of multiple water sources, the comprehensive utilization of surface water, groundwater, precipitation and soil water, the treatment and utilization of waste water and the mixed utilization of brackish and fresh water, and the anti-seepage treatment of reservoirs and reservoirs.

Carry out a comprehensive evaluation of water resources, put forward an optimal allocation plan that can make full use of water resources and give full play to the maximum benefits, and carry out the development and utilization of water resources.

Using the theory of system engineering and fuzzy mathematics, the optimal scheduling model is established, and computer management is adopted to improve the utilization rate of water resources, give full play to the benefits of water resources, realize water saving and increase production, and maintain a benign balance of water resources in irrigation areas.

In the hilly and mountainous areas where there is drought and water shortage, the slopes, pavements, roofs, or places that have been compacted and impermeable are selected to have a certain capacity for flow production as rainwater collection areas, and the rainwater is stored in water cellars or water kilns with a low location, and after purification treatment, they are used for drinking water for rural people and livestock and for crop irrigation.

In areas where groundwater is used as an irrigation water source, the exploitation intensity should be determined and groundwater should be used rationally under the premise of maintaining the ecological balance of groundwater. The machine well is tested and modified to improve the water output efficiency and device efficiency of the machine well and reduce energy consumption. In the irrigation area where wells and canals are combined, when the irrigation season is not in the season, the canal can be used to attract water or the drainage ditch can be used to store the rainfall in the rainy season, and the groundwater can be recharged by human infiltration.
