| 摘 要： | 在生态足迹原理的基础上,将生态压力指数作为生态安全评价的指标,同时制定了相应的指标等级划分标准,对青海省1985—2003年的生态足迹和生态承载力进行了测算,并利用生态压力指数及其等级划分标准对其生态安全进行了试评价。评价结果显示,青海省近11 a来的自然生态处于较安全状态,但生态压力指数呈上升趋势。

| Abstract: | Based on the principle of ecological footprint,ecological tension index and ecological occupancy index for the evaluation of ecological security are presented,and the standards of ranking are constituted.Ecological footprint and its capacity from 1985 to 2003 in Qinghai Province are calculated.Ecological tension index and rank partition standards are used to measure the ecological security of Qinghai Province.The result shows that the ecological security of Qinghai Province in recent 11 years has been the second grade. |
