基于生态压力指数的不同尺度区域生态安全评价

Assessment of ecological safety under different scales based on ecological tension index

  • 摘要: 在生态足迹原理的基础上,提出生态压力指数,并将其作为生态安全评价的指标,制定了相应的指标等级划分标准。利用该评价指标和等级划分标准对全球147个国家或地区及中国部分省、市和县的试评价表明,该评价指标及等级划分标准能很好地运用于不同时空条件下的生态安全评价。

     

    Abstract: Based on the principle of ecological footprint,the paper advanced ecological tension index as an evaluation method of ecological safety,and set out ecological safety classification criteria.Ecological tension index and classification criteria were used to evaluate ecological safety of 147 countries in the world and some provinces,cities and counties of China.Results of the study show that used index and criteria reliably assess ecological safety in both space and time.
