基于敏感性-稳定性-响应3维要素构建指标体系,运用熵值法和ARIMA-BP组合预测模型研究中国人海经济系统环境适应性的演化及预警。结果表明:① 2001~2016年中国人海经济系统环境适应性呈稳定上升态势,总体集中于中警状态,期间经历了“人海环境系统比较优势阶段→耦合协调阶段→人海经济系统比较优势阶段”的双螺旋适应过程,预计2017~2020年再次进入相互契合的轻警状态;② 16 a间中国人海经济系统环境适应性波动存在上升期短-衰退期长现象,预计未来4 a人海经济系统环境适应性在经济下行和生态约束背景下的速率不容乐观;③权衡人海经济系统和人海环境系统的关系,追求总体效益最大化,延长适应性周期波动中扩张期活动,差别化和灵活性的适应行为是未来主要排警对策。 |

Constructing environmental adaptability index system of human-sea economic system based on adaptability factors of sensitivity, stability and response. The entropy method was used to measure the environmental adaptability of human-sea economic system from 2001 to 2016. Combined with ARIMA-BP combined forecasting model, this article forecasts the environmental adaptability of the Chinese human-sea economic system from 2017 to 2020 and makes a detailed analysis of the light display mechanism. The results show that: 1) The environmental adaptability of the Chinese human-sea economic system continued to increase from 2001 to 2016, the warning degree rose from serious alert to slight alert and the indicator lamp turned from orange lamp to blue lamp, and 70% of the years in the medium alert. The environmental adaptability evolutionary process of human-sea economic system is a trade-off between human-sea economic system and the humansea environment system, which experienced a comparative advantage phase of human-sea environment system →coupling and coordination stage→the comparative advantage phase of human-sea economic system. It is estimated that it will re-enter the highly coordinated phase of slight alert state from 2017 to 2020. 2) From 2001 to 2016, there was a short rise period and a long decline in the environmental adaptability of the Chinese human- sea economic system. It is estimated that the rate of environmental adaptability fluctuation of the Chinese human-sea economic system will not be optimistic in the context of economic downturn and ecological constraints from 2017 to 2020. 3) The ARIMA-BP combination forecasting model has a good simulation effect, and it is feasible to apply it to the environmental adaptability pre-warning study of the human-sea economic system. 4) The environmental adaptability evolutionary process of human-sea economic system is unique and dynamic, thus, it is the main policing strategy for the future to weigh the relationship between the human-sea economic system and the human-sea environment system in pursuit of maximizing the overall efficiency and extending the expansion period of adaptive cyclical fluctuations, and to develop a differentiated and flexible adaptation action policy. |
