The impact of road traffic construction on the ecological environment and its ecological effects

The long-term impact of transportation construction on the ecological environment mainly includes the following aspects:

1.Land occupation: Road construction requires the occupation of a large amount of land, which may damage natural ecosystems, farmland, wetlands, etc.

2.Water quality impact: Pollutants discharged during road construction and operation may enter organisms through environmental media (such as atmosphere, water, soil, etc.) and have an impact on water quality.

3.Biodiversity loss: The construction of sheds and roads may damage wildlife habitats, plant communities, etc., leading to biodiversity loss.

4.Impact of urban greening: In the urban ecosystem, road traffic has a great impact on urban green space, which may reduce the overall level and layout of urban greening.

5.Climate change impacts: Transportation construction may lead to increased greenhouse gas emissions, thereby contributing to global warming.

6.Socio-economic impacts: Transport construction may bring economic benefits, but it may also have long-term impacts on the social fabric and natural environment of local communities.

It is important to note that these impacts are not universally applicable to all transport construction and ecological environments, and need to be assessed in the context of specific projects and sites.

Ecological environment. The impact of road or car traffic on the ecological environment includes land, greenery and water quality. Among them, the impact of road construction on the ecology is mainly through two paths:

The first is the non-polluting damage caused by construction activities to the natural environment, which makes the environment physically change and the impact on organisms; Second, the pollutants discharged through the atmosphere, water, soil and other environmental media are trapped into the organism and cause harm. There is also the destruction of open space and wetlands. In the urban ecosystem, road traffic has a greater impact on urban green space, which is manifested in the following ways:

First, it affects the overall level of urban greening; The second is to affect the layout of urban greening.

Reducing temperature: The significance of highway greening ecological construction is to block the road surface and reduce the temperature of the asphalt pavement. Rich landscapes:

The road section with poor scenery can be covered by greenery to lure the beam to guide the line of sight. Noise reduction: Highway greening absorbs car noise.

Safety principle: Effectively shield the lights of the oncoming vehicle and play the function of buffering.

1. Reduce the temperature

With more and more vehicles nowadays, the temperature of asphalt pavement can reach 50-60 degrees in summer, and when the vehicle passes, it is easy to make the pavement permanently deformed, and the tall street trees can block the road surface, reduce the temperature of the asphalt pavement, and reduce the temperature stress.

2. Enrich the landscape

Flexible greening ecological construction, can reasonably eliminate the hidden dangers of accidents, wide road surface can reduce the probability of accidents, scientific planning, increase the beauty of the highway, to achieve a better near view, more transparent vista, poor scenery of the road section, can be covered by greening, induce the line of sight.

3. Reduce noise

In addition to improving the urban environment, highway greening plays an important role in reducing noise, purifying the air, and reducing heavy metal pollution in the soil on both sides of the highway.

4. Safety principle

The principle of planning the greening ecology of the highway should put traffic safety in the first place, so that the slag spring has a good guiding ability, so that the driver can concentrate, according to the change of the highway alignment, to play a guiding role in safe driving, effectively shield the lights of the oncoming vehicles, and also play a buffering function.

In the process of highway construction, operation and maintenance, harmful substances enter the soil, pollute groundwater, and lead to the decline of drinking water and agricultural water quality; The use of snow and snow salts can have adverse effects on water, soil and crops due to changes in the water table and soil contamination, which can reduce crop yields; Automobile exhaust and salt harmful substances affect the growth of trees, flowers and other plants along the highway, and animals near the highway are easily injured and crushed to death by cars; Improper route selection of highways can damage landforms, resting places, scenic spots, cultural monuments and nature reserves.

The construction of highways will change the ecological environment of the areas along the route, and some organisms and populations with special requirements will migrate to remote places or other areas. In addition, the area of activity of animals is reduced, and the territory is redivided, resulting in smaller populations and less communication between populations.

1. Change the structure of the regional road network, promote the industrial upgrading of the region, and promote economic development;

2. Drive the construction and development of cities and towns along the route and accelerate the process of urbanization;

3. It is conducive to the development of circular economy in the region, the construction of a conservation-oriented and friendly society, the realization of the harmony and unity of the regional economy, society, resources and environment, and the promotion of the sustained, rapid and healthy development of the transportation industry.

The best choice for sustainability.

4. It will help the regional material exchange and implement the harmonious development of the regional transportation network 5. The construction of the project provides the necessary conditions for local economic development and commercial prosperity, and will also provide the income level of the people along the line.
