This is true in Europe, but not in Asia. Golden latitude is actually a human concept, which roughly describes the place suitable for the development of animal husbandry, because the formation of golden latitude is related to the prevailing west wind at that time, which is about 40 to 50 dimensions. Although the wind belt can move, on the whole, the western European plain is affected by the prevailing westerly wind, and the ocean brings rich water vapor. The temperate maritime climate is suitable for pasture growth. There are excellent varieties of pasture in Europe, and people have long-term experience in animal husbandry.

There is such a latitude on the earth, which is parallel to the central equator and the North Pole. This is a legend about the growth of animals and plants. 45 degrees north latitude. The area located on this wisdom line is the richest economic resource on the earth today. So this Asian latitude of 45 degrees north latitude is not a golden latitude, and then the southern hemisphere is 45 degrees? The route will not be blocked by tall terrain, such as the Argentine pampas grassland, and the influence of ocean currents will bring suitable precipitation.

Generally speaking, it is also suitable for developing animal husbandry. But overall, 45? Latitude is indeed the development of animal husbandry, so it is called golden latitude. Together, they have formed the reputation of the golden grassland belt. 40 degrees north latitude in Asia is just inside the Great Wall, which is an isorainfall line of about 400 ml, and the interval between latitudes is about11km, so this place is about 600 km north of the Great Wall, and this place is in the north of China.

Although animal husbandry is also very developed, the precipitation is mainly caused by the southeast monsoon, and because of the different monsoon forces every year, the precipitation is often small and unstable. At the same time, Mongolian grassland is seriously affected by the northwest monsoon, and the winter monsoon is extremely dry and cold, which will lead to white disaster or a large number of cattle and sheep losses. Therefore, the climatic factors are much worse than those in the plains of western Europe. ?

Why is 45 degrees north latitude called golden latitude? What's so special about it? Let's call it a day.
