摘要

几个世纪以来,随着社会经济条件、需求和技术可能性的多重变化,意大利森林和森林管理经历了一个动态和复杂的演变过程。在过去的十年中,意大利的森林面积不断扩大,目前已覆盖近1100万公顷,占全国总面积的36.4%。通过对国家森林清查(INFC2005)的分析,描述了森林资源的几个定量和定性方面,包括物种组成、实际和可利用储量、所有权、利用率、可达性、地形特征等。最具代表性的森林类型是“标准矮林”,而许多森林正处于成熟阶段,等待转变为过渡林分。关于森林采伐,全长采伐和绞车-滑动采伐是最普遍的采伐系统,但在许多地区,低开放条件是采伐距离的限制因素,特别是在高坡度地区,可持续和成本效益的作业是主要的。技术进步所带来的现代解决办法,以及日益提高的环境意识和在多个层面上进行可持续管理的需要,都需要有效的森林通讯管理和专业的营运者组成,这是意大利所面临的具有挑战性的情况。

An Overview of forest cover and management in Italy
Over the centuries, alongside multiple changes in socio-economical conditions, needs and technical possibilities, Italian forest and forest management have gone through a dynamic and complex evolution process. In the last decade, forest lands in Italy have been constantly growing and nowadays cover almost 11 million hectars, accounting for 36.4% of the total National territory. Several quantitative and qualitative aspects of forest resources, regarding species composition, actual and available stock, ownership, volume of utilization, accessibility, terrain features and others, have been described through the analysis of the National Forest Inventory (INFC2005). The most represented forest typology is »coppice with standards«, while many forests are in a mature stage, waiting for conversion to transitional stands. Concerning forest logging, full length harvesting and winching-skidding extraction are the most widespread systems, but in many areas the low-openness conditions represent a limiting factor for logging distances, expecially in high slope classes, where sustainable and cost-effective operations are primary. The modern solutions allowed by technological progress, in addition to the growing environmental awareness and need of a sustainable management at multiple level require an efficient forest communications management and professional formation of operators, in a challenging scenario that Italy is called to approach.
