【摘要】：以青岛市-胶州湾为研究对象,选取胶州湾水体中DIN、PO_4-P和COD年均浓度为环境指标,以青岛市人均GDP为经济指标,分析了1980~2010年胶州湾水体环境质量变化与青岛市经济发展的关系。结果表明,胶州湾水体中DIN浓度随时间呈线性增长趋势,但与青岛市人均GDP的拟合关系具有显著的EKC单峰曲线特征,人均GDP约4.5万元/a时出现转折点,此后DIN浓度随经济发展呈下降趋势。胶州湾水体中PO_4-P和COD浓度与青岛市人均GDP呈现"N型"曲线关系,人均GDP约5.2~5.7万元/a时出现转折点。胶州湾PO_4-P浓度随时间呈波动上升,但因胶州湾生态系统中P营养盐相对不足,PO_4-P浓度会受到初级生产过程的影响,其随经济发展的关系并不完全由污染治理相关的经济活动所控制;COD浓度随经济发展有先下降后上升、再下降的趋势,能够显示经济发展的贡献,但更多地反映了点源治理的影响。点源、非点源污染治理和产业结构调整等措施是环境经济关系改善的主因,充足的环保投资则是其经济保障。本研究可为认识其它沿海城市的环境经济关系提供借鉴。
[Abstract]:Taking Qingdao Jiaozhou Bay as the research object, the annual average concentrations of DIN, PO_4-P and COD in the Jiaozhou bay were selected as the environmental indicators. The relationship between the environmental quality change of Jiaozhou Bay and Qingdao's economic development in the year of 1980~2010 was analyzed based on the per capita GDP of Qingdao as an economic index. The results showed that the concentration of DIN increased linearly with time in the Jiaozhou Bay. However, the fitting relationship between GDP concentration and GDP per capita had a significant EKC single peak curve. When the GDP per person was about 45 thousand yuan, there was a turning point in /a. Thereafter, the DIN concentration decreased with the economic development. The concentration of PO_4-P and COD in the water body of Jiaozhou Bay and the per capita GDP in Qingdao showed a "N type" curve, and the per capita GDP was about 5.2~5.7 10000 /a when there was a turning point. Jiaozhou Bay PO_4-P concentration with time rising, but because of the relative lack of P nutrients in Jiaozhou Bay ecosystem, the concentration of PO_4-P will be affected by the primary production process, its relationship with economic development is not entirely by pollution related economic activities; the concentration of COD with economic development have increased after the first drop, then decreased the trend of economic development, can show the contribution, but more reflect the influence of point source governance. Some measures such as point source, non point source pollution control and industrial structure adjustment are the main reasons for the improvement of environmental economic relations, and adequate environmental investment is the economic guarantee. This study can provide a reference for the understanding of the environmental and economic relations in other coastal cities.
