Restoring Mountain Slope Forests by Strip-cutting Shrubs in the Upper Reaches of Minjiang River,Sichuan, China: A Biodiversity-oriented Silvicuture Experiment

摘要

The aims of forest restorationRestoration on of mountain slopes forests is often used to achieveone or a combination of the following aims, should be diverse, and includeincluding increased production, soilprotection and wildlife conservation, .and each development scheme should have a combination of thepurposes In this paper, we proposed biodiversity-oriented silviculture was proposed as a design principle inforest restoration design principle to meet the requirements and then described from which strip-cutting ofshrubs was used as the restoring technology of restoring forests by strip-cutting shrubs that developed formthe design principle. More than 10-year-observations, and experimentals and results of from more than 10years research on the afforestation practices in the upper reaches of Minjiang River, Sichuan, China, indicatedthat the technology was feasible and had many advantages. In the technology, sStrip-cutting of shrubsameliorated microclimate conditions, and improved soil nutrient level for the growth of target tree speciesand. increased The the physical survival of pine species was increased. Structural diversity, in terms ofspecies, was did not much increased, but a shrub species was observed to differentiate from shrub layer andtended to form mixed forests. Preserve belts of the technology were supposed to cover meet public demandsincluding biodiversity conservation and soil protection, and lay a foundation foract as a basic stage inecologically progressive succession. Although it is too early to conclude that this approach is successful in allfunctions, The promising initial resultslook promising indicate that strip-cutting of shrubs may be an effectivepractice for forest restoration in the upper reaches of Minjiang River, Sichuan, China.
