| 摘 要： | 在生态安全评价中,生态足迹模型已广泛被采用,但这些研究多是静态评价,应用生态足迹方法定量计算赞皇县1975~2002年的生态安全度,从时间序列、生态足迹构成和生态压力状况3个方面进行分析,研究表明:时间序列上,生态安全呈下降趋势,已出现生态赤字;生态足迹构成上,各土地类型供需结构不平衡,土地利用结构不尽合理;生态压力状况上,28年间压力指数增幅为1.66,且随时间呈增大趋势。并针对生态安全状况,提出相应对策。

| Abstract: | As an efficiency method,the model of the ecological footprint has been adopted widely,but all these researches usually are focusing on one year's evaluation of a region.In this text the method of ecological footprint was applied to calculate and to analyze the ecological security rate of Zanhuang county from 1975 to 2002.The result indicated in time array,its ecological security was a decline tendency;from component,the ecological supply and demand and the different land use type were imbalance;from ecological pressure,the pressure index amplituded 1.66 during the 28 years and it had a wide growing trendency.Finally,in allusion to the state of ecological security in Zanhuang county,the corresponding countermeasures were put forward. |
