摘　　要：黄土削坡绿化是兰州市南北两山绿化的重点和难点。分析南北两山黄土削坡绿化历程和现状,发现黄土削坡绿化植被退化严重,景观持续性差。通过深入分析,认为退化主要原因:绿化施工质量较差,绿化技术不完善,植物选择失当,后期管护不力,缺乏技术标准规范。为此,提出对策:制定技术标准,切实提高绿化施工质量,完善技术体系,加强科学研究。The greening of loess cutting slopes is the key and difficult point of greening in the north and south mountains of Lanzhou.Based on the analysis of the greening process and present situation of loess cutting slopes in the north and south mountains,it is found that the greening vegetation was degraded seriously and the landscape sustainability was poor.Through in-depth analysis,it is considered that the main causes of degradation are as follows:poor quality of greening construction,imperfect greening technology,improper plant selection,poor management and protection in the later stage,and lack of technical standards.For this reason,some countermeasures are put forward:formulating technical standards,improving the quality of greening construction,perfecting the technical system and strengthening scientific research.
