选取工业废水、工业废水化学需氧量（COD）、工业废水排海氨氮（AN）和赤潮面积4个海洋环境压力指标构建脱钩评价指标，基于Tapio解耦模型，分析海洋经济增长与海洋环境压力解耦状况的时空变化趋势，并应用脱钩指数。结果表明，2002 - 2010年，各海洋环境压力指标与海洋经济增长存在扩张性负脱钩、弱脱钩和强脱钩，且变化趋势不同。从空间上看，渤海经济区海洋环境压力指标与海洋经济增长的脱钩状况表现为最优，表现为稳定的弱脱钩和强脱钩。长三角经济区和珠三角经济区的脱钩状况波动较大，各海洋环境压力指标在不同阶段均呈现恶化趋势。根据研究结果，提出了实现海洋经济增长与海洋环境压力完全脱钩的政策建议。
Four marine environmental pressure indicators were chosen to construct decoupling evaluation index,namely industrial wastewater,the chemical oxygen demand( COD) of industrial wastewater,the ammonia nitrogen( AN) of industrial wastewater discharged into the sea and the area of red tide,to analyze temporal and spatial variation trends in decoupling status between marine economic growth and marine environmental pressure based on Tapio decoupling model with the application of decoupling index. Results showed that there were expansive negative decoupling,weak decoupling and strong decoupling between each marine environmental pressure indicator and marine economic growth with different variation trends from 2002 to 2010. Spatially,decoupling status between marine environmental pressure indicators and marine economic growth of Bohai Sea Economic Zone demonstrated to be optimal with stable weak decoupling and strong decoupling. While there were significant fluctuations with decoupling status of Yangtze River Delta Economic Zone and Pearl River Delta Economic Zone,showing deterioration with each marine environmental pressure indicators during different stages. Corresponding policy suggestions were given based on the results to achieve complete decoupling between marine economic growth and marine environmental pressure.
