| 摘 要： | 以遥感与GIS技术为依托,根据PSR模型框架建立黑河流域生态安全评价指标体系,通过三期生态安全评价数据,综合分析了黑河流域20年来生态安全变化情况,结果表明其生态安全状况总体呈现波动变化,2000年较1986年呈恶化趋势,2007年较2000年有所好转。

| Abstract: | With RS and GIS technology,the index system of ecological security evaluating is set up on the base of PSR framework.Through the evaluation of the three-period data for Heihe river watershed,the dynamics of ecological security during the twenty years was analyzed.The result indicates a fluctuant change of the security status.The situation in 2000 was worse than that in 1986,and in 2007 it was superior to that in 2000. |
