Forest can regulate the temperature. It is a close partner of mankind and an important part of the global ecosystem. Therefore, we must protect the forest. Today, I sorted out the reasons why forest can regulate the temperature_ Why can the forest regulate the temperature for your reference, let's have a look!
The forest and the abiotic environment in the space are organically combined to form a complete ecosystem. Forest is the largest terrestrial ecosystem on earth and an important part of the global biosphere. It is the gene pool, carbon pool, water pool and energy pool on the earth. It plays a vital role in maintaining the ecological balance of the whole earth. It is the resource and environment for human survival and development.
Forest is an area with high density of trees (or historically, forest is a wasteland reserved for hunting), covering about 9.5% of the earth's surface (or 30% of the total land area). These plant communities cover a large area of the world and play an important role in carbon dioxide decline, animal communities, regulating hydrological turbulence and consolidating soil. They are one of the most important habitats in the earth's biosphere.
Why forests can regulate temperature
In summer, trees carry out photosynthesis and transpiration faster, which can quickly release water into the air. The evaporation of water takes away heat, and the forest cools down; In winter, the photosynthesis and transpiration of trees slow down, and it is difficult to emit heat. Moreover, direct sunlight into the forest can also raise the temperature of the forest, so the forest will be warmer. Forests can not only regulate their own temperature, but also play the same role in the whole surrounding environment. Because it absorbs a lot of carbon dioxide, which is the main factor of climate warming, forests can be said to be nature's "green air conditioning".
The important role of forests:
Forest is the "dispatcher" of nature. It regulates the circulation of air and water in nature, affects climate change, protects soil from wind and rain, and reduces the harm caused by environmental pollution.
The forest is the "lung of the earth", and every tree is an oxygen generator and carbon dioxide absorber. A linden tree can absorb 16 kilograms of carbon dioxide a day, and 150 hectares of broad-leaved forests such as poplar, willow and Sophora japonica can produce 100 tons of oxygen a day. If urban residents occupy an average of 10 square meters of trees or 25 square meters of grassland per person, they will have a place to exhale carbon dioxide and a source of oxygen. 67 kilograms of carbon dioxide will release 49 kilograms of oxygen, enough for 65 adults to breathe.
Many trees can absorb harmful gases such as camphor tree, oleander, cloves, maple, Robinia, Ailanthus, juniper, privet, oak, red willow, hibiscus sycamore, elm, Pinus massoniana, Wutong, etc.
Trees have a strong ability to absorb sulfur dioxide, chlorine, hydrogen fluoride and other toxic and harmful gases. These gases pass through the green belt, and usually 1 / 4 can be purified or turned into oxygen.
Forest can conserve water source. It is a huge "reservoir" and plays an important role in the natural circulation of water. "Green mountains are always there, and clear water flows for a long time". Trees are always connected with water. Part of the rainfall is intercepted by the tree crown, and most of it is stored in the withered branches and leaves under the tree and the loose and porous forest soil. Some are absorbed by the plant roots in the forest, and some return to the atmosphere through evaporation. One hectare of forest can evaporate 8000 tons of water a year, making the air moist in the forest area, increasing precipitation, warm in winter and cool in summer. In this way, it plays a role in regulating the climate. The leaves of trees are like a big umbrella, which can prevent the rain from washing the ground directly; The moss on the tree and the withered branches and leaves under the tree can absorb some water.
Forests can prevent wind and sand and prevent soil erosion. When the wind blows, it blocks the way with the tree body and crown to reduce the wind speed. The tree roots are long and dense. It grabs the soil and won't let the wind blow away. The heavy rain falls into the forest, seeps into the deep soil and rock cracks, and flows out slowly in the form of groundwater, which can not wash away the soil. According to the records of Kenya in Africa, when the rainfall is 500mm, the sediment loss of agricultural reclamation land is 100 times that of forest area, and the sediment loss of grazing land is 3000 times that of forest area. Aren't we going to stop desertification and soil erosion? The most effective helper is the forest.
In addition, the forest also plays a role in regulating the microclimate. According to the measurement, in the hot summer, the temperature in the forest land is 3 ℃ - 5 ℃ lower than that in the non forest land. In cold and windy winter, the forest can reduce the wind speed and increase the temperature, so as to warm winter and cool summer. In addition, the leaves of plants in the forest have the function of transpiration water, which can increase the humidity of the surrounding air.
If there were no forests, most of the creatures on the land would be extinct and most of the water would flow into the ocean; Oxygen in the atmosphere will decrease and carbon dioxide will increase; The temperature will rise significantly, and flood and drought disasters will occur frequently. The large-scale deforestation of forests, especially virgin forests, will undoubtedly affect and destroy the ecological functions of forests, resulting in ecological imbalance and environmental degradation in local and adjacent areas, leading to frequent floods, intensified soil erosion, land desertification, river siltation and even the enhancement of global greenhouse effect.
