森林既是天然的水库,又是天然的氧吧,还是天然的空调,更是木材资源的储备库。除此之外,森林的土壤还是污染物质的蓄积库,因为,每一公顷的森林每年就可以吸收20吨的粉尘,粉尘中存在着各种污染物质。由于森林上壤的分布及其物理和化学特性,使它成为特别有效的短期或长期的蓄积库。凡能够从大气中清除污染物,并能将污染物质进行储存,代谢和转化的地方就是土壤。
Forest is both a natural reservoir, but also a natural oxygen bar, or natural air conditioning, but also a repository of wood resources. In addition to this, the soil in the forest is also an accumulation reservoir of pollutants, because each hectare of forest absorbs 20 tons of dust each year, and there is a variety of pollutants in the dust. Due to the distribution of forest soils and its physical and chemical properties, it has made it a particularly effective short-term or long-term reservoir. Where it is possible to remove contaminants from the atmosphere and to store, metabolize and convert pollutants, it is soil.
