Based on the global 30-meter resolution forest cover products and the global 500-meter resolution forest net primary productivity (NPP) products in 2018, this chapter studies the spatial distribution characteristics of forest cover and productivity status at the global, climatic and intercontinental scales, and analyzes the correlation between global forest cover status and global economy, population development, forest management system and management objectives. The global forest area in 2018 is 3.815 billion hm ², Accounting for 25.60% of the global land area; The NPP of forest ecosystem is up to 35.283 billion tC per year, accounting for 55.44% of the global vegetation NPP. The distribution of forests in various climatic zones around the world is uneven. Among them, tropical regions have the largest forest coverage, with an area of 1.847 billion hm ², Accounting for 48.40% of the total global forest area; Similarly, the total amount of forest NPP in tropical regions is also the highest, 24.05PgCyr '(1PgC=1 billion tons of carbon), accounting for 68.17% of the total amount of global forest NPP. From the perspective of each continent, the current situation of forest cover varies significantly. Asia has the largest forest coverage, accounting for 30.91% of the total global forest coverage; The second is South America and North America, with forest coverage accounting for 22.29% and 20.11% of the global total forest coverage respectively. In terms of forest coverage, South America has the highest forest coverage, reaching 47.66%; The second is Europe and North America, with forest coverage of 36.06% and 31.05% respectively. The total forest NPP of each continent is South America, Asia, Africa, North America, Europe and Oceania from high to low, with the highest of 11.78 Pg C yr ', accounting for 33.39% of the total global forest NPP; The lowest is only 1.53PgCyr ', accounting for 4.33% of the total global forest NPP.
