三峡蓄水后,库区水质是否会恶化?中国环境监测总站站长万本太博士认为,不会恶化。据介绍,从2003年5月25日至6月20日,环保监测系统会在库区布设6个监测断面每天监测一次。目前,长江三峡段干流水质以二三类为主,蓄水以后,库区水流变缓可能会影响江水的自净能力,但另一方面,水流变缓也有利于污染物沉淀;有利于岸边水草和其他水生植物的生长,这些水生植物将会吸收、净化一些污染物。此
After the Three Gorges reservoir, reservoir water quality will deteriorate? China Environmental Monitoring Station chief Dr. Wan Bantang that will not deteriorate. According to reports, from May 25, 2003 to June 20, environmental monitoring system will be deployed in the reservoir area of six monitoring sections once a day monitoring. At present, the water quality of the main stream of the Three Gorges of the Yangtze River is dominated by two or three types. After the water is impacted, the water flow in the reservoir area may be slowed down, which may affect the self-purification capacity of the river. On the other hand, the slowing of the water flow is also conducive to the precipitation of pollutants; Aquatic plants and other aquatic plants, these aquatic plants will absorb, purify some of the pollutants. this
