为了避免因为概念上的混淆而带来工程上的众多不便,通过对厚层基质喷附技术发展历程和基本原理的分析,并与国内常用的几种绿化技术比较之后,建议将该技术更名为“有机质喷播技术”。通过实地考察调研和定位跟踪,认为该技术在我国北方地区应用存在主要的问题有:(1)干裂、脱落;(2)坚硬、保水性差;(3)初期草本植物生长过于旺盛,给后期植被恢复带来不利影响;(4)施工、养护成本高;(5)主要材料供给难以为继。为了提高该技术在我国北方地区边坡生态恢复的效果,建议开展专项研究、改进材料配比、开发替代材料、与其他技术相结合。
In order to avoid the engineering inconvenience caused by the conceptual confusion, after analyzing the development history and basic principle of thick substrate spraying technology and comparing with several greening technologies commonly used in China, it is suggested that the technology be renamed as “Organic Seeding Technology ”. Through the field investigation and location tracking, the main problems of the application of the technology in northern China are as follows: (1) cracking and shedding; (2) being hard and poor in water holding capacity; (3) the growth of early herbaceous plants is overly vigorous, (4) The cost of construction and maintenance is high; (5) The supply of major materials is unsustainable. In order to improve the ecological restoration effect of this technology in the slope in northern China, it is suggested to carry out special research, improve the ratio of materials, develop alternative materials and combine with other technologies.
