However, compared to other traditional building materials (e.g. concrete or fired clay) as discussed in Table 2, untreated raw earth has several limitations and disadvantages as its low resistance to compression and tensile loads, vulnerability to water erosion, low resistance to dynamic loads, and high cracking during the drying process [7,8,9].
The earth-based composites are a combination of earthenware powder, aggregate (sand), fiber (straw), earth binders, and water.
The developed earth-base composite (earthenware-based Eco-clay) relies on studied ingredients as the percentage of the binder to the earth and water should be 1:3 whereas the optimum percentage of the earth binders to reach the best extrudable test (1-3) g also the general cracking amount after drying time (1- 4) days as shown in figure.2.As a future work perspective, this study will include a methodology of enhancing earth-based material performance structurally & functionally through the printing process of the shell system by developing an optimization algorithm that controls the infill design pattern to achieve the best performance.
This multidisciplinary approach illustrates how this technology can be used in professional practice.

Introduction
American Forests developed CITYgreen in 1996, which can quantitatively calculate the indicators of trees on its effect and benefit to conserve the soil and water purify the air, fix carbon and release oxygen, reduce energy consumption etc.
Using CITYgreen from remote sensing and satellite remote sensing images, to read the collected various information, such as topography and landforms, vegetation, building, water, even to the different pollutants of diffusion area and harm degree, concealment of geological structure, ore body, groundwater, etc.
The analysis of urban green ecological benefits includes fixing carbon and releasing oxygen, conserving soil and water, renovating atmospheric pollutants, saving energy consumption, etc.
Meanwhile, the relevant coefficient calculation carbon also need to undertake professional determination, this also cause its inconvenience in planning and designing field direct application.

At present, the development of solar energy in our country is largely concentrated in two areas, first, the solar water heater, and the second is photovoltaic power generation.
The research of solar water heater carried out earlier, it has become a large-scale industry, the scale of production and sales are expanding year by year, in urban and rural areas, it gets people's recognition and love.
"Renewable" should also be taken into account, giving priority to consider natural factors, with the resources of clean, renewable, such as solar, wind, renewable water, renewable plant materials in nature, to avoid the exploit-based development path.
Most customers don’t have professional backgrounds, and they are not forward-looking to the landscape designs, and the requirements of designs are mostly from their awareness of the existing landscape works, but few of the existing landscape works are combined with photovoltaic technology, therefore, confronted with breakthrough concept, novel material and high price, many customers feel it difficult to accept.

When using the ion exchange method, the resulting quality of purification allows the use of purified water from heavy metals in the water recycling cycle.
Collection of information and development of a project with its subsequent implementation and technical support requires a professional approach in each individual case.
Therefore, when purifying water, it is necessary to partially desalt it, in other words, to correct all salts dissolved in the water.
This is especially important if purified water is in the circulating water supply, then sulfates will be a source of hard sulfate scale.

Protection of Water Environment.
Set the animal sign for warn ing professional drivers slowed down; Minimize taking and discharging dirts and sandstone ground set in wildlife channels; Construction camps are not set in location where the wild animals are frequent.
So the key of the design is the drainage of this road and water protection.
Study on Protection Technology of Water Environment in Three Jiang Yuan Area.
We can study temporary sewage treatment measures in construction period, and experiment in natural purification of pavement’s water and bridge floor’s water after earthquake.
