Largest forests in the world 世界上最大的森林


Largest forests in the world 世界上最大的森林

A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ. It does not include land that is predominantly under agricultural or urban use." Using this definition, Global Forest Resources Assessment 2020 (FRA 2020) found that forests covered 4.06 billion hectares (10.0 billion acres; 15.7 million square miles), or really approximately 31 percent of the world's land area in 2020.

森林是一片以樹木為主的土地。 全世界使用了數百種森林定義,其中包括樹木密度、樹木高度、土地利用、法律地位和生態功能等因素。 聯合國糧食及農業組織將森林定義為"面積超過 0.5 公頃、樹木高度超過 5 米且樹冠覆蓋率超過 10% 的土地,或能夠就地達到這些閾值的樹木。它不包括 主要用於農業或城市用途的土地。" 根據這一定義,2020 年全球森林資源評估 (FRA 2020) 發現,到 2020 年,森林覆蓋面積為 40.6 億公頃(100 億英畝;1570 萬平方英里),實際上約佔世界土地面積的 31%。
