摘要
针对盐城市生态环境质量逐年下降的情况,在生态足迹原理的基础上,提出生态压力指数作为盐城市生态安全评价的指标体系,并对其生态安全评价。研究表明,盐城市2003年,2005年,2007年生态足迹压力指数为13.40,14.26,20.45。盐城市生态安全一直处于极不安全状态,其发展模式处于不可持续状态。造成盐城市生态安全危机的主要因素是资源过度消耗、人口增长和耕地减少等。
Ecological environment of Yancheng City comes down year by year,based on the principle of ecological footprint,the paper suggests ecological tension index as an evaluation method of ecological safety of Yancheng City and assesses ecological safety of Yancheng City.The result shows ecological tension index of Yancheng City in 2003,2005,2007 were 13.40,14.26,20.45 respectively.Creating the primary factors of ecological security crisis of Yancheng City are the resources consumes excessively,the population growth and the farming reduction and so on.
