What are the three major forest areas in China Tell me about the name and geographical location!

Northeast forest area (Daxing'an Mountains and Changbai Mountains, which are the largest natural forest areas in China).

Southwest forest area (Hengduan Mountainous Area, the second largest natural forest area in China).

The southeast forest area (the mountainous areas of Taiwan, Fujian, Jiangxi and other provinces are the main plantation areas in China).

1. Northeast forest area (three eastern provinces, mainly in the Greater and Lesser Khing'an Mountains).

2. Southwest forest area (mainly in Yunnan Province and Guizhou Province).

3. Northwest Shelterbelt (newly established sandstorm plantation areas are in Inner Mongolia, Shaanxi, Shanxi and Qinghai).

The three major forest areas in China are: the northeast forest area, the southwest forest area, and the southern forest area (also known as the southeast forest area). Among them, the forest area dominated by plantations is the southeast forest area.

Planted forests are forests formed through artificial measures. The purpose of the plantation is clear, and the selection of tree species, spatial allocation and other afforestation technical measures are arranged according to people's requirements.

Its main features are:

The seedlings or other propagation materials used are artificially selected and cultivated, with good genetic quality and strong adaptability;

Tree individuals are generally of the same age and evenly distributed on the forest floor;

The forest was formed with a small number of individual trees, and the group structure was uniform and reasonable.

Trees grow neatly and can enter the canopy state in a timely and uniform manner; The degree of individual differentiation was relatively small after canopy closure and forest growth, and the competition for forest growth was fierce.

The forest land has been under human control since the beginning of afforestation and can adapt to the needs of forest growth. China's plantations have reached 69.33 million hectares, ranking first in the world. Important tree species in plantations include eucalyptus, acacia, masson pine, fir and so on.

Northeast.

The soil is fertile, the water source is sufficient, and the northeast forest area is mostly temperate deciduous broad-leaved forest and coniferous forest, and the combination of water and heat is suitable.

With little human destruction, it is our largest natural forest area. The forest area is mostly divided into mountainous areas, with cold climate and large undulating terrain, which is not suitable for the growth of crops, so forestry is developed.

North China. 1) Less precipitation in winter and spring; In spring, the temperature rises quickly, with strong winds and strong evaporation; Crops require a lot of water. (4 points) (2) preferential policies, coastal location (2 points) (3) located in China's coastal areas; Heavily affected by the summer monsoon; The terrain is low and flat. (2 points) (4) Advantages:

Coal, iron, oil, land, forests and other resources are abundant.

East. South-Central Region.

Southwest. Northwest Territories.

Northeast Forest Area: The main natural forest area in China is currently the most noisy, with an existing forest area of 30.94 million hectares, accounting for.

national; 100 million cubic meters of forest stock, accounting for 32% of the country; Forest cover approx.

It is dominated by coniferous forests and mixed coniferous and broad-leaved forests. After logging and regeneration and artificial transformation management, the proportion of planted forests has gradually increased. The Greater Khing'an Mountains in the northwest are dominated by Khing'an larch forests and felled birch.

forest, secondary forest of poplar; The Xiaoxing'an Mountains are mainly Korean pine forests and coniferous and broad-leaved mixed forests, and the tree species are mostly Korean pines.

leaf pine, spruce, fir, linden, ash, birch, etc.; The forests of the Changbai Mountains are similar to those of the Xiaoxing'an Mountains, except that the number of broad-leaved trees increases, and the appearance of sand pine and pine Changbai.

Southwest China: Located in the southeast of the Qinghai-Tibet Plateau, it is mainly alpine coniferous forest and mixed coniferous and broad-leaved forest.

There is a large difference in altitude in the area, and the forests are mostly distributed in the middle and lower part of the slopes below 4,000 meters above sea level. There is a forest floor.

22.45 million hectares, accounting for the country's; The forest stock is 100 million cubic meters, accounting for the country's.

The main tree species with wood coverage are fir, spruce, larch, alpine pine, birch, alpine oak, etc. The forest area is inhabited by many rare animals, such as giant pandas, golden snub-nosed monkeys, and horned antelopes.

Southeast forest area: The mountainous area in southeast China is vast, the climatic conditions are good, and the forestry production potential is large, which is suitable for vigorously developing timber forests, bamboo forests and a variety of economic forests. Ratio of planted forest to economic forest in forest area.

Important. The main tree species are Masson pine, Huangshan Shengla Xun pine, Chinese fir, cedar, a variety of bamboos (such as moso bamboo, light bamboo, cinnamon bamboo, rigid bamboo), many filial piety evergreen broad-leaved trees (camphor tree, nanmu, quercus, stone oak, etc.), a variety of oaks.

Such as quercus japonica, quercus machinensis, quercus microphylla, beech, etc.).The main economic forest trees are Camellia oleifera, Tung oil, and Wu.

Cypress, lacquer, palm and other tree species.
