The world is full of fragrant flowers in April, and what kind of natural phenomenon does the peach b

It contains the natural phenomenon of the influence of ambient temperature on plants.

It is affected by the vertical difference in temperature. In other words, the reason why the peach blossoms bloom late at Dairinji Temple is because of the "mountainous climate" here. Common sense tells us that in mountainous areas, the temperature decreases as the height of the terrain rises.

Generally speaking, for every 100 meters of height, the temperature drops. The vertical difference in temperature is even more pronounced when the mountains are vertically undulating to a few dry meters. Coupled with the fact that plants have different adaptability to temperature, there will inevitably be differences in the plant landscape at different altitudes.

The altitude of Lushan Mountain is about 1 400 meters, and the temperature at the top of the mountain is generally 8 9 lower than that in the Pingchuan area at the foot of the mountain. Dalin Temple is located in today's Lushan "Flower Trail Scenic Area", which is more than 1 100 meters higher than the plain under the mountain, and the temperature is 6 7 lower than that of Jiujiang City under the mountain; In addition, Lushan Mountain is located between the Yangtze River and Junyang Lake, the rivers and lakes are full of water vapor, clouds and mist, and the sunshine is insufficient, which makes the temperature on the mountain lower, and of course spring comes late.

Detailed explanation: The ancient poet's meticulous observation of the natural world has impressed future generations, and this poem raises a question, why is there all the beauty under the mountain, and the peach and plum are the beginning here? After repeated thinking, Shen Kuo, a scientist in the Northern Song Dynasty, came to the conclusion that this was due to the influence of mountain climate on plants.

Shen Kuo said in "Dream Creek Writings":"Morale has morning and evening, and there is a ...... of depression every dayZhuyue is peach and plum winter, Shuo desert is peach and plum Xia Rong, and the atmosphere here is different.

Lushan Mountain is high, the temperature is low, and spring is late, so that the flowering period is also delayed accordingly. The highest peak of Lushan Mountain is 1747 meters above sea level, and the altitude of Huajing is also above 1094 meters"There is no spring and summer in the mountains, and the February flowers only bloom in April"of the scene.

As early as more than 100 years ago, the British biologist Charles Darwin discovered during his voyage that organisms in nature are distributed according to geographical latitude. In different geographical latitudes, different biological kingdoms live. At the end of the 19th century, the British Hopkins began to conduct long-term phenological observations and formally proposed the phenological law.

Hopkins believes that the stage development of plants is affected by the local climate, which in turn is limited by the latitude, land-sea relationship and topography of the region, that is, phenology is affected by latitude, longitude and altitude.

From the bottom of the mountain to the top of the mountain, the latitude of Lushan has not changed, but the climatic conditions such as temperature and rainfall have changed with the increase of altitude. On average, every 200 metres of ascent, the temperature decreases by 1 degree Celsius. According to the altitude of Dalin Temple at 1100 to 1200 meters, it is estimated that the average temperature is 5 degrees Celsius lower than that of the mountain, and the spring phenology is about 20 days later than that of the mountain.

PS: Because for every certain altitude gain, the temperature drops by 1 degree. Everyone has experienced this, and the top of the mountain is much cooler on a hot summer day. This is also the reason why the flowers on the top of the plain flowers have just begun to bloom, and it is because of this temperature difference.

This verse illustrates the difference between the mountain climate and the plain climate.

The terrain is different, the temperature difference is different, and the growth of the same plant is also different.

The terrain is different, the temperature difference is different, and the growth of the same plant is also different. The temperature is low in the high places.

Bai Juyi. "The world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom" ("Peach Blossoms in Dalin Temple"), which shows the difference between the mountain climate and the plain climate.

Mountain Banquet Mu Vertical Climate and Poetry Tang Dynasty Bai Juyi:"The world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom. There is nowhere to find the spring of long-hate, and I don't know how to turn into this".

It vividly reflects the vertical difference in phenology in mountainous areas as the temperature decreases with increasing altitude. Usually, for every 100 meters above sea level, the temperature drops in Lushan.

The altitude of Dalin Temple is between 1 100 and 1 200 meters, and it is thicker than it"Human"The temperature is about 6 meters lower (the flat land of Jiujiang City, with an average altitude of 32 meters), so the peach blossom bloom time is 20 30 days behind, so the phenology on the mountain is about a month later than the phenology under the mountain.

The world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom. It means: April is the time when the flowers on the plains are withering, and the peach blossoms in the ancient temple of the high mountain are just in full bloom. The disadvantage calendar comes from the Tang Dynasty poet Bai Juyi's "Peach Blossoms of Dalin Temple".

The world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom. "I used (ContrastTechniques. The "fragrant flowers" in the first sentence and the "beginning of blooming" in the second sentence echo each other in contrast.

They are literally imitating bad things, but in fact they are also writing about the leap of feelings and thoughts - from a kind of sad sigh of loss, to surprise and joy, and even to the joy of renting a big search.

The peach blossoms begin to bloom in the mountain temple in April in the world are affected by topographical factors: "the fragrance of the flowers in April in the world" refers to the foot of the mountain or in the plain area, due to the high temperature, the flowers bloom earlier, and the flowers bloom later in the "mountain temple" due to the higher altitude and lower temperature. Therefore, the main reason for the formation of the phenomenon of "the world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom" is the topographic factor.

The peach blossoms in April are all in bloom in April, and the peach blossoms in the temple on the mountain have just opened, indicating that the environment affects the growth and flowering of organisms, and the temperature drops by about 6 for every 1 km above sea level. Therefore, the temperature on the mountain is lower than that below, and the peach blossoms on the mountain bloom later than those under the mountain.

Temperature is a physical quantity that indicates how hot or cold an object is, and microscopically it is the intensity of the thermal motion of the molecules of an object. Temperature can only be measured indirectly by certain characteristics of an object as a function of temperature, and the scale used to measure the temperature value of an object is called a temperature scale.

Wen knows the effect of the hole:

Impact on the natural environment: The overall warming of the earth caused by the uncontrolled emissions of human beings to the atmosphere, the El Niño phenomenon, and the global warming effect also affect the ecological balance of the whole earth and the harmonious development of human beings.

Effect on the human body: Physiologists believe that around 30 is the best ambient temperature for the human body, and it is also the temperature closest to the human **. 33. The sweat glands begin to start, and after working at this temperature for 2-3 hours, the body's "air conditioning" sweat glands begin to start, and the accumulated body temperature is emitted through slight sweating.

35. At this time, the superficial veins dilate, sweating, heartbeat accelerates, and blood circulation accelerates. For some elderly and frail people with poor heat dissipation, it is necessary to cooperate with local cooling, or start the indoor air conditioner to reduce the body temperature.

It contains the dialectical relationship between the universality and particularity of contradictions.

The peach blossoms in the mountain temple are in full bloom in April, which means that April is the time for the earth to return in spring and the flowers to fall, but in the ancient temple in the high mountains, the peach blossoms are in full bloom. This ancient poem embodies the principle of the dialectical relationship between the universality and particularity of contradictions.

From: Bai Juyi's "You Lushan Dalin Temple".

Full text: The world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom.

There is nowhere to find the spring of long-hate, and I don't know how to turn into this

Interpretation: In April in the world, the flowers have withered and have been exhausted, and the peach blossoms in the ancient temple of the high mountains have just bloomed.

I often lament that the spring is gone and nowhere to be found, but I don't know that it has turned here.

Topographic features.

In April, the world talks about the end of Pei Fang Fei, and the peach blossoms in the mountain temple begin to bloom" is said to be that the plain area due to the high temperature, the flowers bloom earlier, and the mountains due to the lower temperature causes the flowers to bloom later, which is the influence of topographic factors on the climate.

The factors influencing climate include latitude, land and sea location, topography, ocean currents and human activities. The sunny slope gets more solar heat than the shady slope; The precipitation on the windward slope is more abundant than that on the leeward slope.

Environmental impact on the growth and flowering of plants, etc., the temperature drops by 6 per 1 km above sea level, so the temperature on the mountain is lower than that under the mountain, and the peach blossoms on the mountain bloom later than the mountain leakage clan There is a natural phenomenon of "the world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom", and the environmental factor that causes this difference is the temperature

So the answer is: this poem describes the natural phenomenon of the influence of ambient temperature on plants

The world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom."Contrasting rhetorical devices

From the sentence "Long hatred of spring is nowhere to be found", it can be known that the poet was resentful, angry, and disappointed by the rush of spring before he arrived. Therefore, when this unexpected spring scene rushes into view, it should make people feel so surprised and delighted.

In the poem, the first sentence of the poem is "fragrant and fragrant", and the second sentence of "the beginning of blooming" is inContrastThe middle and far echo each other. They are literally memorizing scenes, but in fact they are also writing about the leap of feelings and thoughts, from a sad sigh to surprise, joy, and even joy.

Background: This poem is a poem written in Jiangzhou in the early summer of the twelfth year of Yuanhe (817 AD). It is said that in the early summer, the poet came to Dalin Temple, and in April under the mountain, it was already the time for the earth to return in spring, and the time for Fangfei to be exhausted, but unexpectedly in the ancient temple of Gaorang Sun State, he encountered an unexpected spring scene with a blooming peach blossom.

The reason is to cherish the spring, love the spring, resentment of the spring to go ruthless, who knows that it is the wrong to blame the spring, it turns out that it did not return, but like a child and people hide and seek, secretly hid in this mountain temple. This poem describes the spring light vividly and concretely, innocently and lovely, and vividly. The idea is novel, the idea is clever, the artistic conception is profound, full of interest, enlightening people's thoughts, and it is another treasure in the quatrain of the Tang Dynasty.
