The 2016 aerial paving is a necessary element in the planning of the phenomenon. Whether it is a highway or a tree-lined avenue, a municipal square or a wetland park, a commercial center or a children's park, there will be various types of paving.
The paving plan of each kind of place will also have corresponding consideration factors according to the nature of the place. For example, the paving of children's parks will give more consideration to the safety of children's activities. The paving of the carriageway and sidewalk will bear the gravity. There are differences in durability requirements. In order to create a sense of space with different atmospheres in wetland parks and commercial centers, the texture and style of their paving materials can also be very different, but we should have them at the beginning of planning. Emotions of natural awe, no matter what kind of place, should follow the laws of nature, let people live in harmony with nature.
I. Low-impact development methods The concept of "sponge city" has become a hot topic and cutting-edge thinking in China's industry in recent years. The way to establish a sponge city must be the following three points: trivial protection of the city's original ecology; ecological rehabilitation and amendment and Low-impact development methods.

Each of the places where the phenomenon plan is suspended has its own base environment, with different climatic, soil, hydrological, and topographical conditions, as well as the Harajuku residents such as the day and the many flora, fauna, and microbes growing in it.
And following our human urban process, the arbitrary development of land resources has led to the extinction and endangerment of some animals and plants.
The soil has water permeability and air permeability, is a resting place for many organisms, is a transitional environment for biological degradation, and is an important place for purification.
The pavement is a surface layer directly connected to the soil. Assuming that the continuous use of impermeable and impermeable pavements will cause continuous damage to the entire natural environment, it is necessary for us to consider the trivial impact on the original ecology when planning. Minimize the development zone as close to the natural circulation shape as before the development.
Because of this, we should take the natural environment as the basis for the phenomenon planning and take a low-impact development approach [1].
2. Habitat area factor-BAF [BiotopeAreaFactor]. Habitat area factor [BiotopeAreaFac-tor, BAF], which was proposed by Germany in 1980, was originally called a biohabitation index. It was originally a policy-based wrist to advocate environmental results. This kind of urban planning aids accounting.
So far, the urban development and environment part of Berlin [SenateDepartmentforUrbanDevel-opmentandtheEnvironment]. This comment is still used as an environmental ecological standard in urban land development.
The intention of setting up BAF intentions is to keep and create biological resting places in the city, ensure the landscaping standards and visual quality of the urban environment, and increase the green space for citizens' leisure and entertainment.
The BAF of a region represents the ecologically invalid surface [Ecologically-EffectiveSurface]. The ratio of the area to the total land area of the region [to-tallandarea]. The accounting formula is: the larger the BAF value, the ecologically ineffective cover area The larger the corresponding biological resting place index is, the stronger the effect of reducing the heat island effect is and the more sustainable it is.
The higher the water permeability and the higher the cover rate of the plants, the more suitable the organism is for resting, and the higher the BAF index is.
For example, the completely sealed hard paving, which is often used in parking lots, has an index of 0 because it cannot provide any opportunity for living creatures to rest. Part of the hard paving, such as wooden canals and brick paving, has no plant growth, but water and Air can enter, and its bio-resting area index is 0.2.0.3; semi-open paved bio-resting area index is 0.4.0.5; water-permeable paving materials are used [different bio-resting area index is 0.47.0.55 according to the roadbed depth of the paving method ] ..
The covering soil lacks the landscaping of 80cm, and its biological resting area index is widely less than 0.5, and the covering soil is greater than 80cm. For example, the biological resting area index of the food cultivation area is 0.7, and the completely permeable planting area can provide an outstanding resting environment for the organisms. The index is the largest one.
In addition to the following, there are many additional points for advancing BAF values, such as collecting polluted water through water bodies or wetlands, setting up rainwater gardens, cultivating drought-resistant native plants, rainwater storage tanks, vertical landscaping and roof landscaping.
The use of BAF in urban space covers residential land, commercial land, and infrastructure land.
BAF is an ecological minimum standard for urban development planning. All green areas such as yards, roofs, walls and firewalls are included in BAF.
According to the standards of Senate Department for Urban De-velopment and the Environment, the residential area and mixed non-commercial open space dwellings, civil or social public facilities, and kindergartens or day care centers must all have BAF values above 0.6.
For commercial land and commercial land with mixed open space, the BAF value of local commercial equipment, administrative land, school land, and technical basic equipment land must reach 0.3 or more.
The BAF value here is different from our rare landscaping rate. Not all landscaping and paving have opposite ecological coefficients. Therefore, the BAF algorithm assigns a corresponding reduction coefficient to the air of different paving, making the ecological area coefficient ratio Beautification rate can more accurately describe the ecological value of practice.
Invalid ecological surface area formula: Invalid ecological surface area = specific shape surface area x ecological coefficient.
Therefore, in the selection and construction of the pavement planning, we should not only talk about the sustainability of the phenomenon planning from the perspective of the phenomenon pavement. Yin Tang Yanyan Abstract: Through the discussion of the water-permeable ecological pavement, find out the phenomenon pavement materials. And the paving method is conducive to the sustainable development of the environment, which enables the urban development to be inorganically combined with the natural environment, and minimizes the negative effects of the establishment of human cities on the ecological environment.
Analyze the functions and meanings required by the paving from the objective viewpoint of people and the perspective of the big natural objective international.
Through the comparison of various paving methods to stop the habitat area factor [BiotopeAreaFac-tor-BAF]. Or called the bio-resting area index, we love the "low-impact development" criterion, and co-ordinate animalism, applicability, and humanities. Value and aesthetic value seek a balance point in the development of human society and natural environment.

Suspend the review, reach the inorganic balance of human's use of space and the index of biological rest, to achieve low-impact development.
III. Ecological paving methods and materials Water-permeable paving can be used in places such as sidewalks, squares and parking lots: permeable asphalt, permeable bricks, grass-bricks, and permeable concrete.
Therefore, the water-permeable pavement material has fulfilled the primary responsibility of satisfying environmental protection and being able to better serve the needs of people. It is one of the first choices for sustainable development.
Absolutely the traditional non-pervious pavement materials. Permeable materials have the following advantages: 1. Permeable pavement skills can advance the ability of natural infiltration of rainwater in the place, rainwater seeps into the surface, as a complement to groundwater resources, and supply for surrounding plants Part of the water; 2. It can increase the accumulated water on the road surface, prevent pedestrians from slipping on rainy days, and alleviate the trivial pressure of municipal drainage, and correspondingly increase the purification of natural water by air runoff; 3. Its water permeability and moisture retention are The animals and plants and microorganisms installed provide outstanding day space, which well protects the diversity of other biological creatures in the natural world; 4. Due to the special nature of its materials, it has a certain function of absorbing music, and it must be in the management of music purification Auxiliary effect; 5. It helps to alleviate the urban heat island phenomenon. When the moisture stored in the paving material is transpiration, it can cool down the road surface and then improve the heat island effect. 6. Due to the hole-like characteristics of its material shape, it can be avoided Glare, which is easy to occur with reflective materials such as granite, can avoid unnecessary rain skids and glare at night, and is also conducive to urban traffic safety.
4. Different paving places with different functions have corresponding paving choices and have corresponding effects on their BAF index.
1. Sports places: playgrounds, stadiums and other sports and fitness places, traditional concrete and other materials that are relatively impervious to water, you can choose the rubber with excellent water permeability as the unnecessary hard paving part, which has a certain elasticity, which is conducive to running, bouncing, etc. activity.
Coupled with partially sealed hard pavement and vegetation, to ensure that its biological resting index reaches above 0.3.
2. Traffic places: traffic spaces such as roadways, sidewalks, etc. In order to satisfy their use functions, the bioresidence index of the roadway is usually dominated by 0.2, while the sidewalk is more sensitive and the biorecreation index can be higher.
For example, the Tingbu made of natural stone and plants is a semi-open surface, which not only has outstanding water permeability, but also adds some hobbies from the visual effect and participation.
3. Resting places: Leisure-type spaces with recreational functions, such as squares, have many choices of paving materials, and the bio-resting place index can also be higher. Together, they can have outstanding spatial characteristics and build a common space temperament.
4. Parking places: motor vehicle parking places, non-motor vehicle parking places, grass-blocked bricks or other water-permeable bricks can be selected, and the bio-resting index can reach above 0.3.
5. Buffering places: oasis between buildings, etc. If the planting of multi-layer plants is suspended, the bio-resting index should reach above 0.6.
V. The ecological meaning and aesthetic value are very important. Many of our paving plans are three-dimensional construction, and the original intention of the phenomenon planning is a bit far-reaching. Those are the plans that attract the attention in the application of color and composition. The selection of paving materials and the selection of paving methods did not attach importance to integration with the surrounding natural environment, and lacked regional and ecological characteristics.
This kind of planning cannot be said to be a bad one. It just seeks authentic aesthetic value too. It is not a forward-looking plan. It is a plan that lacks environmental protection and is not worthy of large-scale initiatives.
When planners and artists apply the richly conceived decorative ideas to paving planning, please do not ignore their ecological meaning. We must maximize the artistic value and ecological value together.
The concept of the rainwater garden well illustrates the inorganic combination of various aspects, such as the "Vi Day" elderly community in Palo Alto, California, USA. This project not only provides high-quality environmental protection equipment for the elderly residents, but also provides valuable natural and historical Resources and equipment were suspended for protection and enhancement.
Large stale oak groves and sequoia forests are preserved in situ. The close riverfront corridor is paired with decorative grass and native grass species. Various vegetables and herbs are cultivated in the garden near the restaurant. With contemporary sculptures.
Not only its aesthetic value and humanistic care, the water permeability and air permeability of its paving method are based on the planning of the natural ecological cycle, and the people who satisfy the needs of the physical civilization also follow the ecological laws.
Clarify that the human pursuit of the quality of the day, artistic sentiment and the sustainable development of ecology are not contradictory, and can be both.
6. Concluding remarks John O. Simmonds, an ancient American phenomenon planner, said: "Any talented architect, planner, artist can plan a good and interesting space, but the real decision phenomenon profession is ethical and guaranteed. Its irreplaceable position is-ecology.
Therefore, the author believes that from the micro-ecological paving plan to the micro-sponge city, a good phenomenon plan must be the premise of coordinating natural development and human development to ensure the sustainability of the natural environment to the maximum limit. Next, we plan a space for the satisfaction of human activities and achieve harmony and harmony between nature and human society. u=3154912145,4166807330&fm=27&gp=0_meitu_13.jpg
