摘　　要：边坡是在公路和矿山等建设中产生的裸露坡面,边坡植被则是在这些坡面上人为重建的护坡植物群落。虽关于高速公路建设和采矿等对周边环境的生态影响已有较多研究,但专门针对岩质边坡植被修复后的生态评价标准则鲜有报导。本文结合我国公路和矿山边坡复绿工程的实践经验,初步构建了岩质边坡植被重建后的生态评价指标体系,将该体系划分为五个层次:边坡植物个体与环境的评价、边坡植物种群水平的评价、边坡植物群落水平的评价、边坡生态系统功能与服务的评价,以及边坡景观尺度的评价,通过贡献权重将这些指标进行整合得出边坡修复植被的生态评价得分。该评价体系有易操作、针对性强、综合性高、时空跨度广等特点,能弥补当前我国边坡植被修复工程效果评价中生态评价标准之欠缺。该评价指标体系的建立和完善,对推进我国公路和绿色矿山生态边坡的顺利发展会有所裨益。Side slopes are uncovered slope remnants of highway construction and mining activities. Slope vegetation; is artificially restored on these petrous slopes. Although there have been many reports on the impacts of such activities to surrounding environment,few research has been carried out to build the ecological assessment criterion for revegetated plants on side slopes. In this paper,we established an ecological assessment indexes system for petrous slope revegetation,of which consists five levels including：individual,population,community,ecosystem and landscape indexes. These indexes are integrated with their contribution weights to educe the ecological assessment score of slope restored vegetation. This evaluation system is easy to manipulate, spreading expansive spatio-temporal scale with robust pertinency and integration. The establishment of this system would remedy the deficiency of ecological assessment criterion in current slope vegetation restoration, and also would be advantageous to the development of ecological side slopes in highway construction and green mining in China.
