城市裸露的岩质边坡绿化是城市绿地生态构建和管控中工程技术相对复杂但对城市生态景观和生态环境有重要影响的内容,采用植被喷附的斜坡绿化工程方法研究了2种基质对斜坡绿化效果的影响,并从营养学的角度分析了2种基质绿化效果不同的因为.结果表明,2种基质的绿化效果有显著差异,基材良好的养分控释性能是石质斜坡良好绿化的保障,表现为前期促进绿化植物生长,能快速形成绿化景观,越冬后能快速复绿等方面.%Constructing green space system on urban rock slopes is a quite complex engineering problem, but it is also a very important content of urban ecological landscape and environment. The greening effects of two kinds of substrate used for greening rock slopes by Hydromulching system were compared, and the greening effect difference reasons were analyzed from the plant nutrition angle. The result showed that there were significant differences in greening effects of the tow kinds of substrate, and the better nutrients control and release characteristics of the substrate was the key to construct good green space system on rock slopes, which could promote growth of plants in the previous stage, accelerate formation of the greening landscape, and retrieve green fast after overwintering.
