Description
Technical Field
The invention relates to the technical field of ecological garden design, in particular to an ecological garden landscape design green belt for assisting in weakening a heat island effect.
Background
Modern city life rhythm is fast, and the pressure of life can be brought to the urban resident unconsciously. In the high-rhythm and high-pressure life, the ecological garden can be used as a good place for people to go on a holiday. On one hand, the ecological garden can help people to relieve pressure brought by modern life through beautiful landscape of the garden, and on the other hand, the ecological garden can effectively improve the air of modern city life and improve the living environment of people. For modern cities, the existence of ecological gardens can effectively help residents of the modern cities to improve the surrounding environment. Therefore, in modern urban life, ecological gardens have special significance and are widely developed.
Modern ecological gardens have the significance of improving urban environment, but at the present stage, the ecological gardens also have some problems, the problems restrict the development of the ecological gardens and interfere the functions of the ecological gardens, which is a damage to modern greening projects, so that in the modern greening projects, the modern ecological gardens are more careful to avoid some problems in operation and realize the maximization of self value;
researches show that for a long time, the landscape construction generally has the tendency of paying attention to the visual ornamental effect and neglecting the ecological environment treatment. This results in the inability to remediate the urban natural space that is urgently needed on the one hand, and the inability to improve the urban environment that is deteriorating day by day; on the other hand, a large amount of resources are put into the construction of 'fat liquoring and powder smearing type' decorative garden greenbelts and decorative landscapes, so that the urban ecological environment is aggravated to be deteriorated.
The degradation of the overall natural ecological environment causes cities to lose protective barriers which can be relied upon, resulting in the continuous decline of the city's ability to resist natural and environmental disasters. Therefore, the garden ecology aims at improving the overall ecological environment of the city, and various garden greenbelts and plant varieties are arranged according to the specific conditions of urban pollution sources, noise sources, wind directions, heat island effect distribution and the like in a targeted manner, so that the important functions of garden greening in the aspects of purifying air, reducing pollution, weakening noise, improving microclimate, relieving heat island effect and the like are fully exerted, and the city ecology is promoted to be improved fundamentally;
for the heat island effect, the following description is made:
1.1 concept of urban heat island effect: with the rapid expansion of the urban scale, the urban heat island effect becomes more and more obvious. The urban heat island effect refers to the phenomenon that the air temperature in the city is obviously higher than that in the suburb at the periphery. On the near-ground temperature map, the suburban temperature changes little, and the urban area is a high-temperature area, like an island which protrudes from the sea surface, and since the island represents a high-temperature urban area, the island is called an urban heat island in an image manner. The urban heat island effect is a phenomenon that the urban air temperature is higher than that of suburbs.
1.2 cause of heat island effect:
firstly, the influence of the characteristics of the underlying surface (the contact surface between the bottom of the atmosphere and the ground surface) of the city, and the thermal property of the underlying surface is changed by a large number of artificial structures in the city, such as paved ground, various building wall surfaces and the like. The urban ground surface has less water content, and more heat enters the air in the form of sensible heat, so that the air is heated. Meanwhile, the absorption rate of the urban ground surface to sunlight is higher than that of the natural ground surface, more solar radiation can be absorbed, more heat can be obtained by air, and the temperature is increased. In summer, when the lawn temperature is 32 ℃ and the tree crown temperature is 3 ℃, the temperature of the cement ground can reach 57 ℃, the temperature of the asphalt road is higher than 63 ℃, and the high-temperature objects form a huge heat source to bake the surrounding atmosphere and our living environment, so that we can feel heat.
Secondly, urban atmospheric pollution; motor vehicles in cities, industrial production and a large number of people's activities generate a large amount of nitrogen oxides, carbon dioxide, dust, etc., which can absorb energy of heat radiation in the environment in a large amount, and generate a well-known greenhouse effect, causing further warming of the atmosphere.
Thirdly, the influence of artificial heat sources; factories, motor vehicles, residents and the like burn various fuels and consume a large amount of energy, and a plurality of stoves burn and discharge heat;
finally, the natural underlying surface in the city is reduced; the buildings, squares, roads and the like in cities are greatly increased, natural factors such as greenbelts, water bodies and the like are correspondingly reduced, heat release is more, heat absorption is less, and the capability of relieving the heat island effect is weakened.
Means for reducing the heat island effect are: firstly, building a plurality of shade streets to form a banded green channel of an urban area, gradually forming urban area grouping layout taking green as an isolation zone, and weakening the heat island effect; secondly, paving a highway by using novel asphalt with strong water permeability to store rainwater and reduce the temperature of the road surface; thirdly, greening of areas with dense greenhouse gas emission, such as highways, high-altitude corridors and streets, is planned overall, a green ventilation system is built, and fresh air outside the city is introduced into the city to improve microclimate.

The ecological landscape architecture design green belt for assisting in weakening the heat island effect according to claim 1, wherein the water storage part is communicated with a branch pipe through a second high pressure water pump, the branch pipe is provided with an electromagnetic valve, the height of a water outlet of the branch pipe from the ground is adapted to the height of an automobile tire, and a sensor is arranged on the ground at the water outlet of the branch pipe, and when the sensor senses that the automobile passes through, the water outlet of the branch pipe sprays water to the automobile tire.
7. The ecological landscape architectural design green belt for assisting in weakening heat island effect according to claim 1, further comprising a solar energy capturing device as a power source.
8. The ecological landscape architecture design green belt for assisting in weakening heat island effect according to claim 1, wherein the road surface of the urban ventilation corridor is a permeable road surface.
9. The ecological landscape architecture design green belt for assisting in weakening heat island effect according to claim 1, wherein the water mist generation mechanisms in the green belt at both sides of the urban ventilation corridor are symmetrically arranged.
10. A heat island effect auxiliary weakening method is characterized by comprising the following steps:
initial work: establishing an ecological garden with an urban ventilation corridor, arranging green belts on two sides of a road of the urban ventilation corridor, and symmetrically arranging water mist generating mechanisms in the green belts on the two sides;
weakening the heat island effect: when the wind direction faces the urban heat island area and the wind power value meets the expected requirement, water mist with a certain time is conveyed into a wind power flowing layer of an urban ventilation gallery through a first high-pressure water pump and an atomizing spray head, and the water mist flows to the urban heat island area along with air.
