摘  要:基于国内外岩石边坡生态护坡的相关研究结果和基质–植被系统的结构与功能的稳定,通过调查研究,从系统工程学的角度出发,以系统的基质、植被结构、防护功能、物质循环功能与景观文化功能为构建主体,建立岩石边坡生态护坡工程效果评价的五大类指标;并在五大类指标内又划分出各自的具有可操作性的亚类指标,从而形成岩石边坡生态护坡的效果评价指标体系。该指标体系的评价标准将工程效果分为优、良、一般、差和极差5个等级,这些指标较为合理地反映了系统结构与功能的特征与本质,同时表现出结构与功能的相互制约相互依存且在一定条件下可以相互转化的关系。最后结合层次分析法与模糊综合评判方法,将该指标体系用于渝黔高速公路岩石边坡生态护坡工程不同标段的2个工程边坡效果的应用评价中,评价结果与实际观察情况相吻合,说明该指标体系能比较客观地反映工程效果状况及系统功能的持续能力,具有较强的适用性和可操作性。Substrate-vegetation system is the primary functional component of eco-engineering for rock slope protection(EERSP), its structure and function determine the stability and effectively of EERSP. Based on the results of research related to EERSP at home and abroad, and on stability of the structure and function of the substrate-vegetation system, an attempt has been made to establish five types of evaluating indicators including the substrate of system, the structure of vegetation, the protective function, the functions of matter cycling and the landscape cultural functions with a view of systematical engineering by investigations and studies. Further those five types of indicators were marked off the operable sub-indexes that formed the indicator system for evaluating the performance of EERSE The appraisal standards of the indicator system were divided into five grades, such as excellent, well, general, poor and worse, which reflected rationally the characters and nature of the substrate- vegetation system, also exhibited mutual restriction and interdependent relationship between the structure and function. This relationship could transform each other under some special conditions. The indicators were used to evaluate the performance of two slope sections in EERSP of the Chongqing--Guizhou highway by combined analytical hierarchy process(AHP) with fuzzy comprehensive evaluation method. The appraisal results coincided with the in-situ observation, which indicated that the indicator system could objectively reflect the performance and the lasting capacity of function of the substrate-vegetation system.
