一植被是指复盖在地球表面由绿色植物组成的各种不同的植物群落,如森林、灌丛、草原、沼泽以及人类创建的各种栽培植物群落等。在自然界中,植被能够利用光能制造大量物质,直接或间接向人类提供衣、食、住、行等方面的需要,同时,还能够保护和调节人类生存的自然环境。它不仅是国家一项重要的自然资源,而且具有保持水土、涵养水源、调节气候、保护动物生存和保障农业生产等多种效益。因此,在自然界的生态平衡中,占有特殊重要的地位。在各种各样的植被类型中,森林植被最为重要,它既是陆地生态系统的主体,也是陆地生态系统中最大的生态系统。
A vegetation refers to the cover of the Earth’s surface by a variety of green plant flora, such as forests, shrubs, grasslands, swamps and human beings to create a variety of cultivated plant communities and so on. In nature, vegetation can use light energy to make a large amount of material, directly or indirectly to provide human needs such as clothing, food, shelter and transportation, and at the same time, can protect and regulate the natural environment of human existence. It is not only an important natural resource of the country, but also has many benefits such as keeping water and soil, conserving water, regulating climate, protecting animal survival and ensuring agricultural production. Therefore, in the ecological balance of nature, occupies a particularly important position. Among various vegetation types, forest vegetation is the most important. It is both the main body of the terrestrial ecosystem and the largest ecosystem in the terrestrial ecosystem.
