What resources does China lack? What resources are critically lacking? What resources are particular

China's oil, natural gas, iron ore, manganese ore, chromite, copper ore, bauxite.

Potash and other important minerals are in short supply or insufficient proven reserves, and the consumption of these important minerals is relatively dependent on foreign resources, and in 2006, China's oil consumption is dependent on imports.

Most of China's pillar minerals have such problems. The average grade of iron ore in China is only 33, which is 10 lower than the average grade of iron ore in the world, and the iron ore of major foreign iron ore producing countries such as: Australia, Brazil, India, Russia, etc.

A commercial ore grade of 62 can be achieved without beneficiation. The average grade of manganese ore in China is only 22, which is less than half of the world manganese commercial ore industry standard 48, and most of them are difficult to select manganese carbonate. The average grade of copper ore in China is only, while Chile and Zambia.

and 2, respectively. China's bauxite is almost all diaspore monohydrate, and the production cost.

It is much higher than the three waters of the United States, Canada, Australia and other countries.

or diaspore monohydrate. The national average grade of phosphate rock is only 17, the rich ore reserves are only accounted for, and there are many colloidal phosphate rocks, which is difficult to beneficiate. China's sulfur ore is dominated by pyrite, with many poor ores and few rich ores, and the reserves of first-class rich ores only account for it, while most of the foreign countries are dominated by natural sulfur and first-class oil and gas by-product sulfur.

There is a serious shortage of potash in China, and the current use of potassium and magnesium salts in salt lakes is simply not comparable to foreign solid potassium chloride.

Cost-effective compared to development.

According to the country***.

**, by 2020, China's important metal and non-metallic mineral resources available reserves of the degree of security, except for rare earth and other limited resources of 100%, the rest have been greatly reduced, of which iron ore is 35%, copper is bauxite, lead is zinc, gold is. With a minable life of 30 years for limestone, 20 years for phosphorus and less than 10 years for sulfur, potash is now much more needed than supplied.

Judging from the situation in recent years, due to the rapid development of the economy, China has become one of the world's most important consumers of minerals and metals. Some people believe that by 2020, China's iron ore consumption will account for 35 71 of the world's total, and the consumption of more than 20 minerals from high to low coal, tin, zinc, lead, alumina, alumina, lead, copper, etc.

In recent years, China's rapid increase in mineral production has not been able to meet the soaring domestic demand. According to the research of the China Mining Association, by 2020, the 45 major minerals that China needs can be basically divided into four categories: guaranteed, basically guaranteed, shortage, and severe shortage

A total of 24 kinds of minerals can be guaranteed: coal, natural gas, tungsten, molybdenum, silver, rare earth, magnesite, fluorite, refractory clay, phosphorus, barite, cement limestone, glass siliceous raw materials, gypsum, kaolin, stone, diatomaceous earth, sodium salt, miscanite, bentonite, graphite, asbestos, talc, wollastonite.

There are two types of minerals that are basically guaranteed: titanium and sulfur.

There are 10 types of minerals in shortage: oil, uranium, iron, manganese, bauxite, tin, lead, nickel, antimony, gold.

There are 9 minerals that are in severe shortage: chromium, copper, zinc, cobalt, platinum group elements, strontium, potassium, boron, and diamond.

In recent years, China's dependence on imports of oil, iron ore and copper metal has been increasing year by year, especially the dependence of oil and iron ore on imports has increased faster.

Recycled metals need to be industrialized.

Nowadays, both in terms of quantity and quality, scrap metal imports have shown the characteristics of continuous growth.

Ma Junxian, an analyst at Yimao Information, believes that the demand for scrap metal, especially scrap copper, is very large, and the income is far from satisfying the thirst for raw materials generated by many enterprises due to expansion and new construction. The domestic scrap metal has not yet entered the peak period, and the quantity is difficult to grow significantly in the short term, such as copper, which takes more than ten years, so the growth of scrap metal in the domestic market mainly comes from imports.

Scarce resources are resources whose demand is greater than their supply at zero**. Broadly speaking, scarce resources are the key resources that can facilitate the evolution of the system. Without these resources, the speed of system evolution will be severely affected, but having these resources does not guarantee that the system will evolve.

From a professional point of view, there is a certain scope of scarce resources. For example, for China, scarce resources are those resources that are difficult to meet the needs of national construction in China, and they need to be imported to a large extent.

Scarce resource species

1. Rare earth, the general name of 17 metal elements in the periodic table of lanthanides, scandium and yttrium. There are 250 rare earth minerals in nature.

The first to discover rare earths was Finnish chemist John Gadolin. In 1794, he isolated the first rare earth "element" (yttrium, i.e., Y2O3) from a piece of heavy ore shaped like bitumen.

Because of the small number of rare earth minerals discovered in the 18th century, only a small amount of water-insoluble oxide could be obtained by chemical method at that time, and this oxide was habitually called "earth" in history, hence the name rare earth.

2. Petroleum has a natural production state. Petroleum is divided into the forms of **, natural gas, natural gas liquid and natural tar, but it is customary to use "oil" as the definition of "**".

Petroleum is a viscous, dark brown liquid known as the "blood of industry." There are oil reserves in parts of the upper crust. The main ingredient is a mixture of various alkanes, naphthenes, and aromatic hydrocarbons. It is one of the main objects of geological exploration.

Summary. Hello, there is a lack of oil, and it is not abundant enough to rely on offshore oil alone; Lacking timber, the Trans-Khingan Mountains were once Chinese territory, but now they are occupied by Russia, and large areas of forest resources have been lost. There is a shortage of minerals, a large amount of steel is needed for economic development and construction, and the resources of continuous mining are gradually decreasing.

Lack of talents, China does not have independent research and development of computer systems, mobile phone systems, nanochip etching machines can only come from imports.

What resources are most lacking in China?

Hello, there is a lack of oil, and it is not abundant enough to rely on offshore oil alone; Lacking timber, the Trans-Khingan Mountains were once Chinese territory, but now they are occupied by Russia, and large areas of forest resources have been lost. There is a shortage of minerals, a large amount of steel is needed for economic development and construction, and the resources of continuous mining are gradually decreasing. Lack of talents, China does not have independent research and development of computer systems, mobile phone systems, nanochip etching machines can only come from imports.

In the shortage of iron ore, China imports the world's largest amount of iron ore. About 1.2 billion tons of iron ore were imported throughout the year, of which about 700 million tons were imported from Australia, accounting for 60%. And because we have a great dependence on Australian iron ore.

If you think about it in terms of absolute storage, it is indeed helium that is the most scarce, because its content in the air is already very low, and the air contains only 5% of helium. Helium is the least reactive element, and it is a non-combustible inert gas with high thermal conductivity, mainly used as a shielding gas, a working fluid for gas-cooled nuclear reactors and an ultra-low temperature refrigerant, and is also used in semiconductors, optical fiber manufacturing, aerospace and other fields. At present, China's helium extraction technology is relatively backward, and the extracted helium grade is low.

Helium resources are highly dependent on foreign countries, and relevant statistics show that China's annual helium consumption is about 22 million cubic meters, almost all of which rely on imports.

Scarce resources include oil, gold, silver, zinc, platinum group metals, etc.

1. Petroleum: a mixture of gaseous, liquid and solid hydrocarbons, with natural production, known as the "blood of industry".

2. Gold: a metallic element, the element symbol is AU, and the atomic number is 79. The elemental (free form) of gold is commonly known as **, which is a kind of *** and has been used for many centuries as a currency, a store of value, and jewelry.

3. Silver: the physical and chemical properties are relatively stable, the thermal and electrical conductivity is very good, the quality is soft, the ductility is rich, and its reflectivity is extremely high, up to more than 99%, and there are many important uses.

4. Zinc: The chemical symbol is Zn, and its atomic number is 30. In modern industry, zinc is an irreplaceable metal in battery manufacturing and is quite important. Zinc is also one of the essential trace elements in the human body and plays an extremely important role.

5. Platinum group metals: known for their particularly valuable properties and rare resources; Together with gold and silver, it is called "***".

Scarce resources refer to the main meaning: very scarce and precious resources.

Only by using words correctly and understanding the meaning of speech of different words can the expression and interpretation of language be clearer and more accurate, and easy to understand.

Distinguish the meaning of words.

1 The scope of the meaning of the word varies.

For example, "reclamation, development, and development" all have the meaning of "development", but "reclamation" refers to the vigorous development of barren land into arable land;

"Exploitation" refers to the expansion of the original development; The word "development" focuses on new development and new creation, and the meaning of the word is large.

2 The emphasis of the meaning of the word is different.

For example, "talent" and "talent" both contain the meaning of ability and specialty, but "talent" focuses on the ability to do things or the ability to use knowledge, skills, and techniques, while "talent" focuses on the wisdom and expertise revealed in literature and art;

Both "discovery" and "invention" have new meanings, but "discovery" focuses on finding something that already exists, while "invention" focuses on creating something that does not exist in the first place.

3 The meaning of the word is different.

For example, "damage" and "destruction" both have the meaning of destroying objects, but "damage" is generally unintentional, and "destruction" is intentional;

Both "slander" and "false accusation" mean to insist that someone else has done something bad out of nothing, but the former is to fabricate facts and damage others' reputation, while the latter is to falsely accuse and frame others, and the severity of the two is different.

The scarcity of resources refers to the fact that resources are always limited in a certain range of time and space relative to the infinitely increasing demand of human beings, and the scarcity of resources is caused by the relative shortage of resources compared with the absolute increasing demand of human beings.

Definition. Resources are scarce. On the one hand, the goods themselves are finite in a certain period of time; On the other hand, the technical conditions for production from objects are limited, and at the same time, human life is also limited.

The scarcity of material means of subsistence is determined by the scarcity of factors of production. Individuals expect to get a lot of goods and pursue many goals.

The scarcity of resources is the first principle of economics, and all economic theories are based on this principle, because of the scarcity of resources, the human economy and all activities need to face the problem of choice, and economic theories put forward views and arguments around this problem.

Classify. The scarcity of resources can be further divided into absolute scarcity and relative scarcity. Absolute scarcity refers to the total demand for resources exceeding the total supply, and relative scarcity refers to the total supply of resources that can meet the total demand, but the uneven distribution will cause local scarcity, which is usually referred to as relative scarcity.

Frequently touched scarce items can be divided into two categories: one is an item like air that can be freely obtained in any number at will, and they are free goods that do not need to be paid; The other category is the economic goods that must be obtained through means of exchange, called economic goods with scarcity, and there is always a price to pay for obtaining these economic goods.

It is precisely because of scarcity that people are constantly making choices in the use of economic goods, such as deciding what to produce with limited resources, how to produce them, for whom they are produced, and how to make trade-offs among scarce consumer goods and how to use them to meet people's various needs. And it is only when goods are scarce that they can be considered part of the wealth of society.

Imagine if the applicable resources were unlimited, inexhaustible, and could be squandered and wasted, what was the need for economics?

Of course, the scarcity of resources generally refers to relative scarcity, i.e. scarcity relative to people's present or potential needs. This requires that the purpose of socio-economic activities is to achieve the maximum economic effect with the least consumption of resources.

Therefore, the scarcity of resources and the resulting desire of people to achieve maximum economic results with the least consumption are the reasons for the emergence and development of economics as an independent science.

For example: Relatively speaking, there is no scarcity in the air we breathe. Anyone can breathe freely at will.

Therefore, there is no specific study of air distribution. But for most natural resources, they are almost always scarce. Human products are produced by consuming natural resources, so human products are also scarce.

Economics is the study of how to produce, distribute and use these resources and products in order to conserve resources and achieve optimal utility. In the past, water resources were thought to be unlimited, so little attention was paid to regulating the use of water resources through economic means. It now seems that water is a scarce resource.

So we are now advocating for water conservation, and we are starting to focus on the use of economic means to regulate water resources.

The so-called resource scarcity refers to the state in which the resources used to produce the goods or services that people need are always insufficient relative to the needs of people at no cost. Scarcity refers to "the unavailability of goods" in a general everyday sense, but in economic literature, scarcity means "the quantity available is not sufficient to satisfy all needs and desires." ”

Concept hype, theme hype, is the theme of the first to play by the topic.
