Renovation/Maintenance: AR can be used to overlay locations of subsurface electrical, telephone, gas, and water lines onto real-world views.
Monitoring water quality levels in natural water bodies and artificial lakes, monitoring of the pollution levels can be done effectively by using AR.
Soil Mechanics: AR can be used in locating infrastructures for public supply networks (water, sewage, telephone, electric power) in order to avoid damage when intervention to the subsoil is necessary.
Many research works have been given emphasis to the implementation of Augmented Reality for practical applications like manufacturing, medicine, architecture, education and professional training.

The design unit also should use their own professional knowledge make the efficient use of the resources, space and energy and actively using the new construction technology, environmental protection materials and environmental protection technology to provide better design for the urban complex base on the sustainable development.
The construction units should reduce the adverse effects on the environment for construction and production and in the construction water, material selection, waste treatment process using water saving, energy saving, materials saving ideas. 2.4The cost control of urban complex in the operation and maintenance stage In the operation and maintenance phase should focus on strengthening the management of the urban complex maintenance costs, but because of the special nature of the urban complex should also be more control of its operating costs.
This can be done by orderly management system, energy conservation and carbon reduction, and the serial management, solid waste collection and processing, the management of the indoor environment, environmental health management, water saving and energy saving management to the practice of continuous effectively.
Through the timely transformation of water and energy conservation to the urban complex, rational planning replaced the removed materials, rationalize the use of resources, avoid adverse impacts on the environment.

The product was then cleansed with distilled water to remove unreacted chemicals.
Each sample, weighing 2 grams, was submerged in distilled water at room temperature, and the change in water volume was measured.
Furthermore, we assessed water absorption following the ASTM D570 standard [31].
The proportion of water adsorbed by the bio-composite specimens was determined by evaluating the change in sample weight before and after placing in water.
In order to assess the significance of a particular matter, professionals are consulted in order to obtain their expert opinions and insights.

As the B factor, the correct result about choosing the second level or the third level can not get only by mathematical analysis[3], to get realistic excellent combination which requires professional knowledge and experience.

Because of the lack of water and renewable resources, the proportion of non-fossil energy is clearly lower than other domestic cities.
Among them transport emissions grew rapidly and the water transport emissions toke a larger proportion. 1.3 Carbon sequestration reserves Carbon sequestration reserves of Qingdao are not abundant which mainly come from forestry.
We should accelerate the construction of shelterbelt network for coastal area, farmland, road, river together with water source, and the urban forest system.
Qingdao shall establish a public transport-oriented transport system and firmly advocate the development of water carriage, rail transport at the same time.
According to different situations and demands, the related training should be offered respectively including entrepreneurs, senior management personnel, professional and technicist.

Introduction China is the world's gas accident-prone countries, therefore, professional research institutions, universities and research institutes of coal system have invested a lot of manpower and material resources to carry out reaches about coal seam gas emission law, mine gas distribution law, burst danger zone and control technology [1,2].
