Theoretical Study on Vegetation Restoration Ecology of Steep Slope

Abstract

This paper applies the theory of ecology to discuss the effect of vegetation restoration on steep split slope by the vegetation form, the mechanical reinforcement of vegetation roots, the effect of vegetation root angle on soil stability of steep split slop, the effect of vegetation on erosion resisrance of steep split slope. The favorable condition of vegetation restoration for steep split slope is explained in principle, and it provides theoretical reference for vegetation restoration of steep split slope.

Microbial Fertilizers and Shading Contribute to the Vegetation Assembly and Restoration of Steep-Slope after Soil Spray-Sowing in the Yuanjiang Dry-Hot Valley Region

“…The construction of roads, reservoirs and strip mining inevitably results in the destruction of soil structures and surface vegetation [1,2], ultimately leading to large ranges of exposed slopes [3,4], especially in arid and semi-arid mountain areas in southwest China with shallow soil, intense radiation, low rainfall and heavy surface runoff [5]. The restoration of exposed slopes can not only lessen landslides and traffic accidents [6], but can improve the aesthetics and accelerate the rural revitalization that tends to incorporate the development of tourist attractions [7,8].…”

“…The study selected native dominant species and microbial fertilizers for slope restoration trials in the Yuanjiang dry-hot valley. It aimed (1) to compare the differences among artificial seeding, arch column + planting bags, and soil spray-sowing in the Yuanjiang dry-hot valley; (2) to explore the effects of microbial fertilizers and shading treatment on seedling survival and growth after soil spray-sowing; (3) analyze the restoration benefit among different slope degrees, which answer the following two questions: (1) what methods and treatments are most appropriate for slope restoration in dry-hot valleys? and (2) what are the survival and adaptation mechanisms of different species?…”
