Why did our ancestors choose our mostly barren land as their homeland?

The best land in the world is owned by China and the United States. Generally speaking, the geographical environment of the United States is slightly better than that of China, but the United States has a fatal flaw, which I will reveal at the end of the article.

In this article, I will briefly analyze which land environment is best between China and the United States from the aspects of geographical location, topography, climate conditions, etc. You will be grateful after reading this article Our ancestors chose this fertile land as their homeland.

01 Topography

From the perspective of topography, the situation in China and the United States is basically the same, with mountains and plateaus in the west and plains and hills in the east, with the terrain gradually decreasing from west to east.

However, in terms of the area of ??plain terrain that is the most suitable for living and living, the US data seems to be better.

The plain terrain area of ??the United States is about 4.82 million square kilometers, accounting for more than 40% of the country’s land area. Among them, the area of ??the Central Plains alone reaches 1.536 million square kilometers, accounting for 17% of the United States’ land area. .

The plain area of ??our country is only 1.15 million square kilometers, which is only 1/4 of the plain area of ??the United States and accounts for 12% of China's land area. The vast land in western China consists of mountainous and plateau terrain that is uninhabitable.

Obviously, from the perspective of plain area, the geographical environment of the United States has more advantages.

02 Freshwater Resources

In terms of water resources distribution, my country’s water resources are not scarce. After all, we have the Qinghai-Tibet Plateau, commonly known as the “Water Tower of Asia”. However, the distribution of water resources in my country is extremely uneven. Tibet, which has the richest water resources, is not suitable for human habitation due to its alpine climate, while the densely populated eastern coastal provinces are plagued by water shortages.

In addition, as far as the eastern region is concerned, it also presents a dilemma of more in the south and less in the north. The biggest bottleneck restricting the development of the north and northwest is water resources, while the south often suffers from floods due to the arrival of the summer flood season. .

The total amount of freshwater resources in the United States is slightly larger than that in my country. The total amount of water resources in the United States is 2.9702 billion cubic meters, and the per capita water resource is close to 12,000 cubic meters. It is one of the countries with relatively abundant water resources.

In addition, since the United States has the Great Lakes in the northeast, the Mississippi River in the vast central region, the Colorado River in the southwest, abundant rainfall in the southeast and northwest, and the Columbia River in the northwest, water resources are more evenly distributed.

So, from the perspective of freshwater resource distribution, the United States has the advantage among the two countries.

03 Climate

In terms of climate, because the central part of the United States is the Central Plains, the warm and humid air currents from the Gulf of Mexico can drive straight into it, bringing abundant precipitation to the United States, making the climate of the United States more oceanic. Obviously, the climate is milder and wetter.

The climate of the United States is as follows:

(1) Western coastal area: The western coastal area from north to south is: temperate ocean climate? Mediterranean climate? Tropical desert climate;

< p>(2) Southeast coastal area: subtropical monsoon climate;

(3) Central plain area: mild temperate continental climate;

Needless to say, China’s climate characteristics Yes, we have an obvious continental monsoon climate. Because it is close to the Asian high pressure, winters are dry and cold, and the climate is obviously continental. Compared with other countries at the same latitude, the climate has a larger temperature difference and uneven seasonal distribution of precipitation.
