基于DPSIR模型的山东半岛蓝色经济区海洋生态可持续发展能力综合评价

DPSIR Model-based Assessment of ecologically sustainable development in Shandong Peninsula Blue Economic Zone

山东半岛作为我国最大的半岛,其地理位置决定了海洋生态可持续发展对其的重要性。本文使用DPSIR(驱动力-压力-状态-影响-响应)模型,结合社会经济和自然生态两个方面搭建指标体系评估其蓝色经济区生态可持续发展能力。结果表明:山东半岛承受的社会经济压力正不断增大。海洋生态系统综合状态评价值为0.53,其中海水、沉积物质量及生物综合评价值分别为0.22、0.19及0.123,生态环境现状不容乐观。影响和响应评价值分别为2.5和4.3,海洋灾害的影响范围较大,危害程度较深,但海洋管理部门在面对生态环境变化时的反应较为迅速、有效。

Shandong Peninsula is the largest peninsulas in China and its geographical position plays a vital role in its ecological health. In this paper, we used the Driving-Pressure-State-Impact-Response （DPSIR） model, combined with social economic and natural ecological parameters, to establish an ecologically sustainable development evaluation index system. The results show there to be increasing social and economic pressures on the Shandong Peninsula, and the comprehensive state evaluation value for its ecological system is 0.5313. The water, sediment and biological quality values are 0.22, 0.19, and 0.123, respectively. Current conditions are not encouraging. The impact indicator and response indicator values are 2.5 and 4.7, respectively, which indicates that marine disasters have great influence on the Peninsula and can cause serious damage, although the government’s response to changes in the ecological environment is typically quick and efficient.
