基于PSR模型的河北省生态安全评价研究

Ecological Security Assessment of Hebei by PSR Model

着眼于河北省粗放型经济发展模式与日益恶劣的生态环境之间的矛盾,基于"压力-状态-响应"(PSR)模型,选取人口、环境、资源、社会经济等方面30个指标,构建河北省生态安全评价指标体系,利用熵值法从时间尺度上对河北省生态安全状况进行综合评价与分析。结果表明:2005-2014年间,河北省生态安全综合评价指数整体呈现上升趋势,说明河北省的生态安全状况有所好转。最后提出加强河北省生态安全建设的对策思路,为建设成为生态强省提供依据。

Focus on extensive economic development mode in Hebei Province and the contradiction between the increasingly severe ecological environment,based on the 'pressure- state- response'( PSR) and the stress- state- response( PSR) model,this paper selects 30 indicators of population,environment,resources,socio- economy to construct the ecological security evaluation index system of Hebei Province,which used to evaluate and analyze the ecological security situation of Hebei Province from the time scale by entropy method. The results showed that the overall ecological security index of Hebei Province showed an upward trend in 2005- 2014,which indicated that the ecological security situation of Hebei Province had improved. Finally,the countermeasures to strengthen the ecological security construction in Hebei Province are put forward,which will provide the basis for building a strong ecological province.
