日本是世界上较早进行高速公路建设的国家之一 ,至今已有 60 0 0 km以上的高速公路。几乎是在大规模基础设施建设的同时 ,对边坡的治理和绿化以及对建设中遭破坏的植被的恢复在日本兴起和发展。加之日本国土有限 ,对于水土保持和绿化十分重视 ,其绿化的工艺、技术、设备都具有国际先进水平。这里仅就喷播在边坡生物防护和绿化方面的应用以及喷播技术在日本的研究和发展作一介绍。 Japan is one of the countries that started the construction of the expressway in the world earlier. Up to now, there are more than 600 km of expressways. Almost at the same time as large-scale infrastructure construction, the harnessing and afforestation of slopes and the restoration of damaged vegetation during construction have risen and developed in Japan. Coupled with Japan’s limited territory, for the soil and water conservation and greening attaches great importance to its greening technology, technology, equipment have the international advanced level. Here only to spray sowing in the slope of biological protection and greening applications and spray technology in Japan to introduce research and development.
