中文摘要:
      结合长江经济带城市的生态特点,基于驱动力-压力-状态-影响-响应模型构建具有长江经济带特色的生态安全评价指标体系,然后通过主成分分析方法求取指标权重,运用灰色系统理论建立生态安全评价模型,并以武汉市作为实证研究对象,对其近十年的生态安全状况进行评价,并根据评价结果,提出相应的对策建议。研究结果表明:武汉市2001-2014年间生态安全水平总体呈上升趋势,其中2014年生态安全水平最佳,达到较良好水平。
英文摘要:
      The paper is based on the ecological features of the Yangtze Economic Belt Cities and the Drive-Pressure-Status-Influence-Response model. It constructs an ecological security evaluation index system with characteristics of the Yangtze economic zone, and then obtains the weights of the indexes by principle component analysis, and builds the ecological security evaluation model by using the gray system theory. It takes Wuhan City as its object of study and evaluates Wuhan's ecological security status in the recent ten years. Based on the results of the evaluation, the paper offers suggestions. The results of the study show that the ecological security level during 2001 and 2014 is rising on the whole, and that it reaches a peak in the year of 2014 with excellent ecological security.
