- 摘要：
自20世纪以来，特别是近50年，随着人口的快速增长，城乡工业的迅猛发展，大量的工业污染，生活污染物质排入秦淮河水系，造成秦淮湿地严重退化，直接导致秦淮河流域生态状况和水环境质量下降，为了提高对秦淮河生态状况和其在城市生态系统中功能和影响的认知，在调查秦淮河全段生态环境质量的基础上，利用湿地生态系统健康评价指标体系，比较和评估了外秦淮河和秦淮河上游的生态环境状况；并根据外秦淮河作为自然-经济-社会复合生态系统的特点，重点对其水环境恶化的现状和生态实质进行了研究分析。最后结合生态学原理和整体最优原则提出了外秦淮河治理的五条对策，为改善南京城市水环境提供决策依据。 - 关键词：

Nanjing city and running the local ancient
culture, plays a great role in the geography,
water environment and urban development of
Nanjing. However, since last century due to urban
population explosion and swift industry
development, a large amount of wastewater and
sewage are produced, Qinhuai River has been
severely polluted and its wetland ecosystem was
degraded. This directly caused the deterioration
of Nanjing city's water environment. In order to
increase our knowledge of current ecological
state of Qinhuai River and its function in urban
ecosystem, after investigating the entire drainage
area of Qinhuai River, an indicator system
was used to assess the state of wetland ecosystem
health. Particularly, the problems and their
eco-essences of Qinhuai River in Nanjing area
are discussed and analyzed on the basis of an
economic-social-natural compound ecosystem.
Correspondingly, five countermeasures for wetland
restoration and water environment improvement
are advanced.
