绿色植被损伤,森林衰亡与空气,水体和土壤受污染程度的关系,这些都是生态环境研究的重要问题。除了对自然环境中污染物的直接监测外,对受污染的生物体本身进行监测也是一个方面。在国内近年开展的酸雨研究中,人们通过对植物可见伤害症状的观测及植物器官离体的生化指标测定,已获得二氧化硫、氮氧化物等对植物生长影响的一些知识,但这些监测手段 The relationship between the damage of green vegetation, the decline of forest and air, water and soil pollution are all important issues in ecological environment research. In addition to the direct monitoring of contaminants in the natural environment, the monitoring of contaminated organisms themselves is also an aspect. In the acid rain research carried out in China in recent years, people have obtained some knowledge about the plant growth affected by the observation of visible damage symptoms and the biochemical indexes of plant organs in vitro. However, these monitoring methods
