为清楚阐明蒙古栎林的群落分级及其在温带落叶阔叶林群落分级中的地位,我们收集了东北亚201个蒙古栎林和日本的153个栎林的资料.将其综合于一个简表中.并应用Braun—Blanquet方法对这些森林植被进行了比较。结果表明:在温带落叶阔叶林的群落分级系统中。蒙古栎林与水青冈纲占据着同等重要的地位,它们共同构成温带落叶阔叶林纲群(Class-group)。不同生境下的蒙古栎的20个群集或群落被归纳成为2个目、3个群团和3个亚群团。  相似文献

“复关”将给中国林业带来巨大的挑战和前所未有的机遇。森林相对不足,林产工业水平低下,决定了中国林业尚参与国际竞争的实力;贸易环境的急剧变化,市场保护能力的降低,以及双重加的市场推动,将对林业的发展造成冲击,前景不容乐。但与此同时,林业也将获得稳定的贸易环境以及调整产业结构和增强竞争实力的动力和条件。面对挑战和机遇,我们必须改变思维,在关贸总协定的框架内寻求对策,制定措施。  相似文献

Sustainable forestry is considered as one of the most important focal points for sustainable development, as it is part of the United Nations Conference on Environment and Development held in Rio in 1992 which followed the completion of “Our Common Future.” To this end, many studies have been carried out on implementing of sustainable forestry at the global level.

Geographically, Turkey can be seen as part of Pan-European and Near East sustainable forestry initiatives. Forest organizations have carried out many studies to implement the decisions made with these initiatives in line with their own needs in forest management. While conducting studies in the framework of the National Forestry Program prepared within this context, people have been confronted with various problems due to insufficient infrastructure and implementation difficulties. This article provides information on sustainable forestry leading to observations and suggestions relevant for Turkey.  相似文献

About 80% of annual wood fiber consumption in Japan is imported. Even though most of the land surface is covered by forests in Japan, the domestic forestry and forest industry are threatened by such imports flooding the local market. Fragmented land ownership, steep terrain, rapid growth of weeds, and high labor costs have all contributed to the decline of domestic forestry. Further, the purchasing power of the Japanese Yen has become very strong in recent years, and the decreasing prices of imported timber have depressed the prices of domestic timber, eroding profitability and discouraging small-scale forestry. In spite of these difficult circumstances, there are several interesting new developments in Japanese forestry. One is the revision of the Basic Forestry Law of 1964, through which the Japanese government is steering forest policy from timber production towards environmental services. Because of this change, new ways to assist rural forestry activities will become available in the near future. Another change is the certification movement, where recent examples of Japanese companies acquiring ISO 14001 and Forest Stewardship Council (FSC) forest certifications provide hope to depressed domestic forestry activities. In particular, FSC group certification is useful in motivating small-scale forest owners to implement and maintain sustainable forestry practices. This paper is based on the presentation at IUFRO Group 3.08.00 Symposium at Joensuu, Finland 2001. The original article, ‘The economic situation of small-scale forestry in Japan’, is in Niskanen and Vayrynen (2001).  相似文献

In Indonesia, working and living conditions of forestry workers are quite unfavorable because of very severe thermal conditions at the workplace and because forestry work is heavy, dirty and dangerous, requiring a poor working posture and exposure to noise and vibration. In addition, forestry workers often live under conditions where housing, infrastructure and hygiene are poor compared with those of other industrial workers. The objective of this study is to improve these unfavorable conditions by clarifying the working and living conditions of forestry workers and identifying factors affecting their job satisfaction. Our results showed that many of the forestry workers had low back pain and that attention should be paid to muscular exertion, especially while lifting heavy objects such as chainsaws or logs. Several accidents and near-miss incidents happened while driving and engaging in forestry work. To prevent such accidents, it is important to supply forestry workers with more personal protective equipment and to establish traffic rules on forest roads. The results also showed that most forestry workers were dissatisfied with their salary. In addition, the analysis of potential factors affecting job satisfaction showed that younger workers, chainsaw operators, manual workers and office workers were dissatisfied. It should be noted that many respondents thought that sustainable forest management was essential. To enhance their satisfaction levels, their working and living conditions, and, in particular, salary should be improved, and forest resources should be monitored to prevent over-cutting or forest fires.  相似文献

森林生态与资源信息共享系统的建立与应用   总被引:1,自引:0,他引:1  
林业生产活动和科学研究过程中积累了大量基础数据、统计数据和图件,随着社会对森林生态环境的关注,迫切希望这些长期获得保存的信息能够为更多的人共享.森林生态与资源信息共享的服务领域涉及公众服务、科学研究、政府决策,也是国家可持续发展信息共享平台不可或缺的组成部分.本文运用近年兴起并得到广泛应用的网络数据库技术、WebGIS技术,实现基于Internet的森林生态与资源信息共享系统.虽然,网络数据库技术和WebGIS技术已经很成熟,但是用于国家宏观林业资源信息与生态信息的整合、共享与发布,还是不多见的(张旭等,2001).  相似文献

80年代以来,世界林业发展趋势是:由传统林业向生态化林业转变;由传统的永续利用向持续发展转变;由单纯开发天然林向培育人工速生林转变;由生产锯材和胶合板向生产各种纸产品和非单板型人造板转变;由传统经营模式向持续经营转变。据此,作者提出在制定我国林业产业政策时,应优先考虑扩大森林资源;实行林工结合、优化结构、内引外联、行业管理;国家大力扶持;依靠科技进步,实现优质、高产、高效和持续发展;保持林业管理机构和政策的长期稳定。  相似文献
