What are the advantages of 40 degrees north latitude, the more the merrier, from a global point of v

The climate has obvious seasonal changes and is suitable for life.

The topographic units passing through China at 40 degrees north latitude from west to east mainly include the Tarim Basin, the Taklamakan Desert, the Loess Plateau, the Inner Mongolia Plateau, the Yellow River, the Taihang Mountains, the North China Plain, the Bohai Sea, and the Liaodong Peninsula.

China's topography is high in the west and low in the east, and is distributed in a stepped manner. The terrain is varied, with a vast mountainous area. The terrain is high in the west and low in the east, and it is inclined to the ocean, which is conducive to the moist air flow over the ocean to penetrate deep into the interior and form precipitation. On the other hand, many large rivers have flowed eastward, connecting the east and the west, and facilitating the economic ties between the coastal areas and the interior.

The river descends from west to east, and the river has a large drop, and the water energy is abundant. The diverse terrain has provided favorable conditions for the development of diversified agriculture, forestry, animal husbandry, and sideline operations in accordance with local conditions. Mountainous areas have advantages in the development of forestry, animal husbandry, tourism, mining, etc.; However, the mountainous area has a rugged ground and inconvenient transportation, which is not conducive to the development of planting industry.

Due to the vast area of mountainous areas and the small number of plains, there is a shortage of cultivated land resources.

40° north latitude is the latitude code of the geographical location of the capital Beijing, which is located along the Fifth Ring Road in Beijing, connecting the Capital International Airport, the Olympic National Forest Park, Zhongguancun, Xuefu District and the Old Summer Palace and other national precious resources. From the perspective of China and even Asia, 40° north latitude is China's political and economic hinterland and the cultural center of Asia. Due to its unique geographical and ecological advantages, 40° north latitude is the world's finest milk and wine production area.

From a broader global latitude, 40° north latitude traverses many well-known cities such as Dandong, Beijing, Beidaihe, Dunhuang, Madrid, Istanbul, Ankara, Salt Lake City, Denver, Washington, New York, and Philadelphia.

In the Beijing Botanical Garden, there is a geographical indication line along the 40th parallel. The 40th parallel is an important and mysterious line. There are a lot of world-famous cities on this line.

From 35°N to 70°N, there are Eurasian continents and North American continents, and the mid-latitude regions within these continents have a large area of temperate continental climate, characterized by cold winters and hot summers, scarce precipitation, and large annual temperature ranges. The high latitudes have a cold climate, which is cold all year round and has relatively little precipitation.

Between 35°S and 70°S latitude in the Southern Hemisphere, most of the area is oceanic, there is no large area of land in the mid-latitude region, and there is the Antarctic continent in the high-latitude region, which belongs to the ice sheet climate.

40°n latitude:
