中国的整体水环境和水生态问题已经到了危机的状态,以本人长期研究的长江流域为例,流域部分江段水体污染严重;近70%的湖泊处于富营养化状态,太湖、巢湖等这些曾经美丽的湖泊,都因为污染严重而一度带来地区的水安全危机;大量湿地严重退化,导致湖区水安全保障能力降低;长江渔业资源严重枯竭;长江流域水鸟栖息地的减少和破坏直接威胁着众多稀有鸟类的生存,生物多样性面临严重破坏。这种情况在全国其他流域有过之而无
China’s overall water environment and aquatic ecology have reached a crisis. Taking the long-term study of the Yangtze River basin as an example, the water bodies in some sections of the river basin are seriously polluted. Nearly 70% of the lakes are in an eutrophic state. Taihu Lake and Chaohu Lake, Beautiful lakes all brought the water security crisis in the region once because of the serious pollution. The serious degradation of a large number of wetlands led to the decrease of the water security ability in the lake area. The fishery resources in the Yangtze River were seriously depleted. The reduction and destruction of waterfowl habitat in the Yangtze River directly threatened many Survival of rare birds, the biological diversity is facing serious damage. This situation has been neglected in other drainage areas throughout the country
