树木体内的含硫量随不同树种和不同部位而异;树木具有吸收二氧化硫的能力,树体平均含硫量随季节而变化;树叶含硫量高低,直接反映大气污染情况,可用于监测和评价SO_2污染程度。
The sulfur content of the tree body varies with different species and different parts; the tree has the ability to absorb sulfur dioxide, the average sulfur content of the tree changes with the seasons; the sulfur content of leaves directly reflects the atmospheric pollution, can be used for monitoring and evaluation SO_2 pollution degree.
