摘　　要：针对都汶公路沿线地质生态环境承载力波动效应等问题,该文以都汶公路沿线区域为研究对象,利用地理省情普查及监测数据,探讨了生态地质环境系统内部各动力要素间的协同耦合机制。通过对公路沿线生态地质环境影响因素的分析,探索并构建了宏观—中观—微观联动的地质生态环境承载力本底库及评价指标体系,采用层次分析法计算各个评价指标的权重系数,揭示都汶公路沿线生态地质环境脆弱性变化的影响因素、机制和规律,界定都汶公路生态地质环境承载力阈值。结果表明,该评价体系及评价方法考虑了西南地区的"震后效应",适合于开展山区地质生态环境变化趋势研究。Aiming at the problem of wave effect of geo-ecological environment carrying capacity along Dujiangyan-Wenchuan hJLghway, this paper discussed the collaborative mechanism between inner driven forces o{ the geo-ecological environment based on the geographic census monitoring data. The geological environment carrying capacity database and its evaluation index system which are linked from macro to mi- cro were built through analysis of the factors about geo-ecological environment along highway; AHP method was used to calculate the weight ratio of each evaluating indicator to reveal the factors, mechanism and regulation of the vulnerability changes of geo-ecological environment along Du-Wen highway; mean- while, the threshold pf bearing capacity was defined. Experimental result proved that this evaluation system took into account the ＂post-earthquake effect＂ in south-west area and was appropriate for variation tendency of geo-ecological environment in mountainous region.
