中文摘要:

      产业结构变化对生态环境影响深远。本文分析了2001—2016年南京市产业结构演进轨迹和高级度变化，采用Spearman相关分析法定性描述了三产比重对生态环境的影响，利用生态环境影响指数定量分析了产业结构的生态环境效应，并通过产业高级度和生态环境影响指数的相关性分析研究了产业结构升级的生态环境效应。结果表明：①研究时段内全市产业结构总体经历了一次转型，产业结构高级度总体呈现逐年上升趋势；②第一产业、第二产业产值占比与SO₂排放量、NO_x排放量、SO₂年均浓度均呈正相关关系，第三产业产值占比则与其均呈负相关关系；③全市产业结构生态环境影响属于中等，产业转型引起的生态环境效应轨迹与产业结构变动轨迹在变化趋势上存在一致性，且要滞后于产业结构转型。随着产业结构高级度的提高和产业结构升级的加速，南京市生态环境会得到改善。

英文摘要:

      The transformation of industrial structure had a far-reaching impact on the ecological environment. This paper analyzed the evolution trajectory of the industrial structure and the change of advanced level of Nanjing in 2001-2016, described the influence of the proportion of three industries on the ecological environment with the Spearman correlation analysis, quantitatively analyzed the ecological environmental effects of industrial structure by the ecological environmental impact index, and studied the ecological environment effect of industrial structure upgrading through the correlation analysis of industrial advanced level and ecological environment impact index. The result showed that:① the overall industrial structure of the city had undergone one transformations during the study period, the advanced level of industrial structure had been increasing year by year; ② the proportion of the first and second industries output value had a positive correlation with SO₂ emissions, NO_x emissions and the average annual concentration of SO₂, while the proportion of the third industrial output value was negatively related; ③the ecological environmental impact of the industrial structure belonged to the medium. The track of ecological environment effect caused by industrial transformation was consistent with the changing trend of industrial structure, and it lagged behind the transformation of industrial structure. With the improvement of industrial structure and the acceleration of industrial structure upgrading, the current ecological environment will be improved.
