grassland

desert

The main types of vegetation in my country

grassland

Most of the plants that make up the grassland are herbaceous plants adapted to semi-arid climate conditions.

desert

The ecological conditions of the desert are harsh, with hot and dry summers, poor soil, sparse vegetation, poor species, and drought tolerance.

Rainforest

Tropical rainforests are located in areas with high temperatures and rain all year round. They are particularly rich in plant species, evergreen all year round, and tall.

evergreen broadleaf forest

Evergreen broad-leaved forests are distributed in areas with hot and humid climates, and are dominated by evergreen broad-leaved trees.

1: Forest resources are scarce and unevenly distributed

According to the results of the fifth national forest resources inventory (1994-1998), the overall situation of my country’s forest resources is:

The forest area is 1.5894×108 hm2; the forest coverage rate is 16.55%;

The main problems faced by vegetation in my country

1. Forest resources are rich in plant species, but my country is still a Shaolin country. Below is a comparison of forest coverage:

Among them, the per capita forest area is only 0.128 hectares, which is only equivalent to one-fifth of the world's per capita level. What is the reason for this situation?

2: The area of ​​grassland forest and grassland is decreasing day by day and showing signs of degradation.

Strategies for Sustainable Development of Vegetation Resources

(1) Manage forests in accordance with the law and strengthen resource protection, such as: "Forest Law", "Grassland Law", "Resolution on Carrying out National Compulsory Tree Planting Movement"

(2) Strengthen the progress of afforestation and greening, improve the area of ​​green space and the quality of afforestation
