| 1 | Past,present and future of industrial plantation forestry and implication on future timber harvesting technology显示文摘Plantation forests are established,and expanding,to satisfy increasing global demand for timber products.Shifting societal values,such as safety,productivity,environmental,quality and social are influencing the plantation forestry sector.This is primarily driven through an ever increasing world population,which in turn influences the way nations view the value systems by which they live.More people require more resources-also forest products.Also,the availability of information is influencing the pace of technological development.These changes could result in a difference in the management of plantations that could affect the forest engineering systems of the future.This review aimed to summarize the current status of plantation forests;summarize future developments and possible scenarios in forest plantation management for the various products;and assess whether these developments in a plantation environment could affect the harvesting systems used.Factors influencing the form of plantations include the type and nature of the plantation owner;the change in demand for different and new forest products;climate change factors,including the use of biomass for energy,carbon sequestration and trading;ecosystem services and other products and services;and sustainability certification of forest management.The impact and influence of these factors were summarised into a series of key drivers that will influence the technology used in harvesting machines,as well as the choice of harvesting machines,systems and methods.These drivers were the effect of variations in tree size,the expansion of plantation areas onto more difficult terrain,diversity in plantation design,increased attention towards site impacts and the increased use of biomass for energy.Specific information is provided regarding how the harvesting systems could be affected. | Andrew McEwan Enrico Marchi Raffaele Spinelli Michal Brink | 2020 | Journal of Forestry Research2020，31，2： | 3 |

| 4 | Performance of a small-scale chipper for professional rural contractors显示文摘The study determined the productivity,fuel consumption and product quality obtained with a new tractorpowered drum chipper,designed to reduce the gap between industrial chippers and small-scale chippers.The machine was tested with poplar logs and beech slabs,considered as representative of the raw material commonly used for energy wood production.After accounting for accessory work and delays,productivity of green chips ranged between4 and 6 tons per scheduled machine hour,which was very good for a tractor-powered unit.Specific fuel consumption of oven-dry chips varied between 2.5 and 3.0 L per ton,or 0.6 L per m3.These figures compared favourably with those obtained from previous studies of both smaller and bigger chippers.Chip quality was very good.Samples contained no oversize particles,qualifying for use in small-scale plants.The average size of beech chips was significantly larger than for poplar chips,possibly due to the higher strength of beech wood. | Raffaele SPINELLI Natascia MAGAGNOTTI | 2013 | Forestry Studies in China2013，15，3： | 0 |
| 5 | Exploring the silvicultural and economic viability of gap cutting in Mediterranean softwood plantations显示文摘Gap cutting consists of the removal of all trees growing on a small surface,varying in size from 200 to 600 m 2.In Italy,gap cutting has been successfully tested for introducing the natural regeneration of native species into softwood plantations,thus accelerating the transition towards climax hardwood stands.Depending on plantation types and conditions,gap cutting should be started at an age between 70 and 80 years and the system should include at least 12 to 15 gaps,in order to produce enough wood to cover costs.Generally,natural regeneration is firmly established within 5-7 years from treatment.Gap cutting also offers superior results to selection thinning,the latter producing about 35% less value and incurring 25% to 30% more costs.As for all regeneration cuts,the success of gap cutting depends on wildlife control in order to prevent extensive damage to the regeneration. | Roberto MERCURIO Raffaele SPINELLI | 2012 | Forestry Studies in China2012，14，1： | 0 |
| 6 | A Novel Intermediary Framework for Dynamic Edge Service Composition显示文摘Multimedia content,user mobility and heterogeneous client devices require novel systems that are able to support ubiquitous access to the Web resources.In this scenario,solutions that combine flexibility,efficiency and scalability in offering edge services for ubiquitous access are needed.We propose an original intermediary framework,namely Scalable Intermediary Software Infrastructure (SISI),which is able to dynamically compose edge services on the basis of user preferences and device characteristics.The SISI framework exploits a per-user profiling mechanism,where each user can initially set his/her personal preferences through a simple Web interface,and the system is then able to compose at run-time the necessary components.The basic framework can be enriched through new edge services that can be easily implemented through a programming model based on APIs and internal functions.Our experiments demonstrate that flexibility and edge service composition do not affect the system performance.We show that this framework is able to chain multiple edge services and to guarantee stable performance. | Claudia Canali Michele Colajanni Delfina Malandrino Vittorio Scarano Raffaele Spinelli | 2012 | Journal of Computer Science & Technology2012，27，2： | 0 |
