中文摘要以青岛市-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...
英文摘要Dissolved nitrogen and phosphorus in surface waters of the southwestern nearshore area of the Laizhou Bay and the adjacent 10 rivers that it connects with were surveyed in September 2012 and the long-term variation trends of them were studied based on the historical data of the past 30 years. The main findings are as follows: (1) The average total dissolved nitrogen concentrations of the 10 rivers ranged from 1.82 mg/L to 10.66 mg/L, most of which exceeded the river-water standard Grade V of China. (2) The average dissolved inorganic nitrogen concentrations in 3 transects (Xiaoqinghe river transect, Yuhe river transect, Bailanghe river transect) of the 5 surveyed nearshore transects exceeded the seawater standard Grade IV of China (0.5 mg/L); the average active phosphorus concentrations in 4 sections of the 5 surveyed nearshore sections were below the seawater standard Grade I of China. (3) The nutrient concentrations in the upper reaches of some estuaries maintained a high level, which maybe correlate to intense mixing of seawater and freshwater. The nutrient concentrations in the western part of the studied area were higher than those in the bottom part of the Bay. The nutrient concentrations of the Dihe River in the bottom part of the Bay were especially higher. Crude oil mining activities may affect nutrient content and morphology of the neighboring aquatic body. ( 4) The average concentration of inorganic nitrogen in the Laizhou Bay experienced a transition from a low level to a high one, which was worse than the seawater standard Grade IV of China after the year of 1995. (5) Since the late 1980 s, phosphorus has been in the nutrient limiting phytoplankton growth in the Laizhou Bay, and the molar ratios of nitrogen and phosphorus were higher than Redfield threshold ( 16) for most of the survey period, but the extent of phosphorus limitation has eased relatively in recent years.
