一、森林生态系的特征:森林生态系的结构非常复杂,覆盖着各个植物群落的演替期和顶极群落。森林可改变局部气候条件,具有形成各种微小气候、水份和土壤的高度储留等特点。大部分有机生命物质都在地面的植被上,矿物质的循环缓慢,储留量很大。土壤的形成基本与人的活动无关。 First, the characteristics of forest ecosystems: The structure of forest ecosystems is very complex, covering the succession and climax community of each plant community. Forests can change the local climatic conditions, with the formation of a variety of microclimate, water and soil height retention and so on. Most of the organic life material is on the ground vegetation, the slow circulation of minerals, storage capacity is large. The formation of soil has nothing to do with human activities.
