脆弱性研究已成为全球环境变化领域一项新的研究视角和重要的分析工具。本研究在人海系统的基础上提出了人海资源环境系统的概念,利用脆弱性这一新的研究范式对环渤海地区人海资源环境系统进行分析。人海资源环境系统脆弱性是关于敏感性和适应性的函数,采取熵值系数法进行权重赋值,并采用函数模型法进行脆弱性测度研究。结果表明:①从时间维度上分析,环渤海地区脆弱性呈现了波动性的变化,总体上是下降趋势,并出现了三次“倒U”型发展态势;②从敏感性指标上分析,环渤海地区呈现了“先降后升再下降”的趋势,捕捞过剩以及废水废物排放是敏感性的主要影响因素;③从恢复性指标上分析,环渤海地区恢复性不断上升;在经济快速发展的过程中,注重资源环境的保护和利用,尽量避免产业的雷同,努力发展新兴产业成为了提高恢复性的途径;④从空间维度上分析,环渤海地区人海资源环境系统脆弱性的下降速度呈现出山东省>辽宁省>天津市>河北省的趋势,人海资源环境系统敏感性的下降速度呈现出天津市>辽宁省>山东省>河北省的趋势,人海资源环境系统恢复性的上升速度呈现出山东省>河北省>辽宁省>天津市的趋势。
Vulnerability research has become a new research perspective and an important analytical tool in the field of global environmental change. Based on the human-sea system, this study proposes the concept of sea resources and environment system and uses the new research paradigm of vulnerability to analyze the human resources and environment system around the Bohai Sea. The vulnerability of human resources and the environment system is a function of sensitivity and adaptability. The entropy coefficient method is adopted for weight assignment, and the functional model method is used to study the vulnerability measure. The results show that: ①According to the analysis of time dimension, the vulnerability of the Bohai Rim region shows the change of volatility, which is generally a downward trend and a trend of “Inverted U” three times; ② Based on the analysis of the sensitivity index, In the Bohai Rim region, the trend of “first decreasing then rising and then falling”, the over-fishing and waste water discharge are the main influencing factors of sensitivity; ③Analysis of restorative index shows that the recovery in the Bohai Rim is increasing; In the process of rapid development, focusing on the protection and utilization of resources and environment, trying to avoid similarities in the industry and striving to develop new industries became the way to improve recovery. ④ From the perspective of spatial dimension, the human resources and environment system in the Bohai Sea Rim The rate of decline shows the trend of Shandong Province, Liaoning Province, Tianjin Municipality and Hebei Province. The declining speed of sensitivity of human resources and environment system shows the trend of Tianjin, Liaoning Province, Shandong Province and Hebei Province, and the recovery of human resources and environment system The upward trend of sexuality shows the trend of Shandong Province> Hebei Province> Liaoning Province> Tianjin City.
