摘要: [目的] 基于微立地的概念对工路边坡立地类型进行划分,为提高公路边坡植被恢复措施的针对性、更好地选配工程绿化方法、降低工程成本、提高边坡植被的成活率和保存率。[方法] 以华北东部廊涿(廊坊至涿州)高速公路、京石(北京至石家庄)二通道高速公路大苑村至市界段及京承(北京至承德)高速公路沙峪沟至市界段的边坡为研究对象,运用实地边坡调查和室内试验分析相结合的方法,调查分析高速公路边坡各立地因子,通过对标准化后的立地因子数据进行方差分析、主成分分析及分层聚类分析后划分立地类型。[结果] 共划分出6个高速公路边坡立地类型组:平原土质路堤边坡、平原土质路堑边坡、丘陵土质路堤边坡、丘陵土质路堑边坡、平原岩质路堑边坡和丘陵岩质路堑边坡,以及24个高速公路边坡立地类型。[结论] 将华北东部高速公路边坡立地类型与中国森林立地分类相结合,得到华北东部高速公路边坡立地类型系统,提高了边坡绿化的科学性和合理性。

Abstract: Based on the concept of micro-site coditions,the site types of highway slope were divided,in order to improve the pertinence of slope vegetation measures, to select better method for green engineering, to reduce project costs, and to improve the survival rate and preservation of slope vegetation. [Method] Slopes of Beijing-Chengde highway (Shayugou to the city boundary), Langfang-Zhuozhou highway and Beijing-Shijiazhuang two-channel highway (Dayuancun to the city boundary) in the east of north China were studied. both field surveys on highway slopes and laboratory tests were combined to investigate all the site factors. Then the data of standardized site factors were analyzed by the analysis of variance, multivariate statistical principles of factor analysis and hierarchical cluster analysis.[Result] Six site groups of highway slopes were determined: plain soil embankment slope, plain soil cutting slope, hilly soil embankment slope, hilly soil cutting slope, plain rock cutting slope, and hilly rock cutting slope. The 6 site groups of highway slopes were divided into 24 site types. [Conclusion] Finally, a site type system of highway slopes in the east of Northern China was obtained by combining the forest site classification in China and the site types of highway slopes in the east of north China, which is aimed at improving the scientific basis and rationality of slope revegetation.
