摘要

With deep-processing material of surface resources as soil substrate, the experiment of soil spray sowing was carried out on expressway slope. The results show that taking surface soil of fine particles and compost product of surface organic plant residue as the main soil substrate for slope soil spray-sowing greening in the initial vegetation restoration can significantly speed up the vegetation propagation velocity on the side slopes, which can promote slope vegetation to maintain reasonable proportion of grass and shrub, help to increase the diversity of the communities, and promote the slope vegetation community to evolve toward the native direction. Surface resources obtained by surface cleaning in development and construction projects are valuable ones that can be reused. The related researches show that the valuable surface resources contain not only rich organic matter, nitrogen, phosphorus, potassium and other nutrients, but also soil seed bank consisting of livable seeds which are the potential plant population or community as well as the material basis of naturally updating the vegetations [1]. USA, Japan and other developed countries have attached great importance to topsoil stripping and utilization, formed a mature management system and technical means, and carried out related researches on vegetation restoration effect of topsoil utilization [2-4]. Researches show that the backfilling and utilization of natural topsoil after stripping can increase the biological diversity in the soil [5-6], and also speed up the vegetation succession which is available for early development of local shrub [7]. In recent years, more and more attention has been paid to topsail utilization in highway construction, and some practical applications are carried out in the process of some highway constructions [8-10]. However, surface resource utilization in the process of highway construction is still stuck in the simple level of backfilling utilization, and some clear researches on deep-processing and comprehensive utilization of topsoil and organic plant residues on the surface obtained by surface cleaning in highway construction have not been reported. To implement the in-depth study on making full use of surface resources in vegetation restoration on the sides of highway, protect the ecological environment of soil source area, promote the formation of shrub and grass vegetation, solve the intensive grass-based problems in spray-sowing greening, the research has relied on Guangzhou-to-Lechang expressway project, made surface soil of fine particles and residue compost product of surface organic plant as the main soil substrate of slope soil, and combined with spraying technology to carry out practical researches for a useful attempt to further exploring the technology of deep-processing and comprehensive utilization of surface resources in vegetation restoration of highway side slopes through contrast test of the restoration effect on vegetation.
