环境监测是环境保护的“耳目”。环境污染物除可用物理的或化学的方法监测外,近年来,我国在利用植物监测和评价环境质量,特别是监测和评价大气污染强度方面已做了不少工作。从研究资料来看,过去利用植物监测和评价环境质量多着重于敏感植物的指示作用及植物受害症状与大气污染度的关系等方面,利用城市常见的绿化树种,特别是利用具有一定抗性的乔木树种进行定量监测和评价,以及直接利用树木叶片氟积累量的相对值来评价大气氟
Environmental monitoring is the “eyes and ears ” for environmental protection. In addition to the monitoring of environmental pollutants by physical or chemical methods, in recent years, much work has been done on the use of plants for monitoring and evaluating the quality of the environment, especially for monitoring and evaluating the intensity of atmospheric pollution. From the research data, the past use of plant monitoring and evaluation of environmental quality and more emphasis on the role of sensitive plants and plant damage symptoms and the relationship between the degree of air pollution, etc., the use of common urban greening trees, especially the use of a certain resistance Tree species quantitative monitoring and evaluation, as well as direct use of the relative value of tree leaf fluorine accumulation to evaluate the atmospheric fluorine
