Introduction

With the sustained and rapid development of China's national economy, the intensity of infrastructure construction and mineral resources development and utilization is increasing, coupled with natural disasters. Damage to the slope and vegetation damage caused by the damage, the bare slope increased sharply, and vegetation restoration is urgently needed. The special site conditions of the exposed slope It is difficult to meet the needs of such bare slope vegetation restoration, and it is urgent to formulate corresponding technical standards. To standardize the vegetation restoration project of bare slopes in northern China, and improve project quality and ecological benefits. Restoration of bare slope vegetation requires the integration of geological features, geotechnical engineering, civil engineering, materials engineering, forestry equipment, soil and water conservation, soil, Forest cultivation, vegetation, ecology, hydrology, landscape and environment, etc., are comprehensive application of engineering machinery, engineering materials, engineering measures and plants. Measures in the field of forestry engineering technology. This standard is based on the latest research results and mature technologies for the restoration of bare slope vegetation at home and abroad. On the basis of this, the organization of relevant domestic research and teaching institutions and enterprises jointly proposed. Technical specification for vegetation restoration of bare slopes in northern areas

1 Scope

This standard specifies the technical requirements for investigation, design, construction, maintenance and inspection of bare slope vegetation restoration. This standard is applicable to the surface vegetation damage or soil parent material caused by human or natural factors above 25° (inclusive) in the northern region. Lost bare slope vegetation restoration.
