Distribution of agriculture PPT, the third part: three major forest areas

Forests have very important environmental benefits and huge economic benefits for human survival and development.

Using forest growth, you can obtain wood and a variety of economic forest products, such as rubber, fruits, tea, etc.

1. There are many types of forest resources in my country

There are more than 20,000 species of woody plants in the world, and my country has about 8,000 species, accounting for 40% of the world's woody plant species, of which there are more than 2,000 species of trees.

my country is also very rich in bamboo resources, with about 30 genera and more than 300 species. It is the country with the most bamboo resources in the world.

2. my country’s total forest resources are large but per capita is small.

Daxinganling - the last forest kingdom

Daxinganling is the largest state-owned forest area in my country, where there are concentrated and well-protected northern virgin forests.

After discovering the fossils of marine life on the stone walls of Daxinganling, we learned that the predecessor of Daxinganling was the sea.

Human transformation of water and wetlands has destroyed the ecosystem here, and "old man trees" have grown in the deep mountains and old forests.

Most of the ethnic groups in northern my country arose in the Greater Khingan Mountains and then migrated out. Daxinganling has changed from a prosperous world to a quiet historical backyard time and time again.

This is a paradise for cold-resistant animals. Neither tigers nor monkeys can survive in the alpine zone of Daxinganling. The wild deer has the largest number and variety in the Daxingan Mountains, and is the most loved animal by humans.

3. The distribution of forest resources in my country is very unbalanced.

There are more forest resources in hilly and mountainous areas in the northeast, southwest and southeast regions.

However, the vast northwest region, the densely populated and economically developed North China region, and the lower reaches of the Yangtze and Yellow Rivers have less forest resources.
