森林在自然界中的作用,日益为人们所瞩目,它不仅向人类提供木材和林副产品,而且在保护环境、改造自然、保证农牧业稳产高产,特别是在保持整个自然界的生态平衡方面起着极为重要的作用。植物有净化环境的能力,对各种污染物都有吸收、积累、分解和代谢作用,能降低大气中有毒气体的浓度,而且能保持大气层中氧和二氧化碳的平衡,减少空气中放射性物质的浓度,减弱躁声,杀菌除尘,净化环境污染。同时,由于不同树木对不同污染物的敏感性不同,又可用来监测预报环境污染,以此来增强人们对森林资源的重视和保护意识、共创我们美好家园。
The role of the forest in nature has drawn increasing attention. It not only provides wood and forest byproducts to human beings, but also plays an important role in protecting the environment, transforming nature and ensuring a stable and high yield of agriculture and animal husbandry, especially in maintaining the ecological balance of the entire natural world Very important role. Plants have the ability to purify the environment, have a variety of pollutants have absorption, accumulation, decomposition and metabolism, can reduce the concentration of toxic gases in the atmosphere, but also to maintain the balance of oxygen and carbon dioxide in the atmosphere, reducing the concentration of radioactive substances in the air , Weaken noise, sterilization dust, purify the environment pollution. At the same time, different trees have different sensitivities to different pollutants and can also be used to monitor and forecast environmental pollution so as to enhance people’s awareness of forest resources and protect their awareness and create a beautiful home.
