The development and construction projects have led to a large number of artificial slopes and ecological damages. The ecological restoration has greatly accelerated the control process of soil erosion, and highlighted the great role of soil and water conservation in the construction of ecological environment. However, in some especially difficult sites, general ecological restoration technology can not work and meet the people' s requirements. Therefore, the engineering revegetation technology for the difficult sites will be widely studied and applied. The concepts, technical systems and application types of the engineering revegetation technology are analyzed and discussed in this article.%开发建设项目导致了大量的人工边坡和生态破坏.生态修复的开展大大加快了水土流失的治理进程,彰显了水土保持在生态环境建设中的巨大作用.然而在一些特殊困难的立地条件下,普通的生态修复技术就不能凑效,无法满足人们的要求.因此,针对困难立地的生态修复技术——工程绿化技术便得到广泛的研究和应用.对工程绿化技术的概念、技术体系、应用类型等方面进行了分析论述.
