我国的竹资源丰富,具有重要的生态、经济和文化价值。山东栽培竹子历史悠久,“南竹北移”的成功极大丰富了山东竹子栽培利用的经验,为北方竹子种质资源保存和竹产业发展奠定了良好的基础。竹产业的转型升级为北方竹林发展提供了良好的机遇。新时代发展北方竹产业,要着眼于竹产业服务国家战略,立足地域特色,明确发展定位,科学规划发展方向,深化产学研合作,丰富经营模式、拓展竹产品种类,不断延长竹产业发展链条,依靠科技引领竹产业创新发展。 相似文献

拉丁美洲和加勒比地区是世界主要的竹资源分布区,以瓜多竹为代表的560多竹种资源占全球竹种的33%,其中巴西、哥伦比亚、秘鲁、厄瓜多尔、墨西哥等国竹林面积和竹种数量位居该地区前列。与亚洲相比,拉丁美洲和加勒比地区现代竹产业发展起步较晚,规模和效益有限。面向未来,该区竹资源主要分布国家的政府正在制定和实施相关政策和战略,助力竹区发展经济、缓解贫困和保护环境。 相似文献

The primary objectives of this study were to describe and compare the competitive strategies of softwood sawmills in five major softwood producing regions of the world, and to discuss the limitations of the well‐known Porter model. Data was collected via personal interviews from 102 companies in Finland; coastal and inland western USA; coastal and inland British Columbia, Canada. Results suggest that “pure”; focus and differentiation strategies are the competitive strategies most commonly followed by sawmills in Finland and inland British Columbia. In the coastal and inland western USA regions “pure”; differentiation and “pure”; cost leadership strategies are dominant in these two geographical regions, respectively. In coastal British Columbia a “pure”; cost leadership strategy and the combination of all strategy types were the two strategies most frequently followed. The competitive strategy followed was found to be related to company size. Large companies more often applied cost leadership strategies and differentiation and focus strategies were typical of small and medium‐sized companies. In general, sawmills in all five regions had difficulties identifying exclusively with one strategy type. 相似文献

Forest management strategies, reflecting the cognition and the demands of the human population on forests, have significant effects on the forest structures and functions. Nowadays, numerous forest management strategies have been introduced and implemented worldwide for a long time. However, our knowledge about the impacts of alternative management strategies on forest multipurpose management practices is still insufficient. Therefore, the overall goal of this study quantitatively assessed the impacts of four alternative forest management strategies on forest timber and carbon values in a large forest area in northeast China, as an example. Four alternative forest management strategies: no intervention management (NIM), classical timber management (CTM), multi-purpose management (MPM), and spatial-constraints management (SCM), in conjunction with different management objectives and regulations, were quantitative assessed using optimization methods. The results of numerical analysis showed that implementing eco-friendly forest management strategies such as imposed in MPM and SCM strategies may be economic inefficiencies, mainly due to significant decreases of the joint benefits from forest timber and carbon values (approximately $18.75 and $22.36 million per year) have been observed under the current carbon trading market of China (namely $20 per ton of carbon) when the ecological- and spatial-oriented constraints were further integrated into the typical CTM strategy. However, both MPM and SCM strategies were quite meaningful for the restoration of forest resources in northeast China, in which an additional of 13.6 and 16.2 thousand tons of carbon were sequestrated during the 50 years simulated horizon. Therefore, forest decision makers should evaluate the potential effects carefully prior to altering their forest management strategy in practices. 相似文献

The objective of this study is to assess drivers and barriers to primary forest fuel (PFF) supply in the wide-stretched South East Europe (SEE) countries and to develop strategies to improve PFF supply involving dozens of stakeholders from different SEE countries. SWOT (strengths, weaknesses, opportunities and threats) analyses were used to evaluate country supply chains. Based on those a regional SWOT analysis was compiled and strategies were developed and evaluated in a participative decision process. Results show that strategies for increasing biomass utilisation are of high relevance in all participating countries. Additionally, strategies for knowledge dissemination are also important. The evaluated regional strategies for the forest fuel sector examined have great potential to improve cooperation, increase efficiency and strengthen competitiveness of PFF based bioenergy production. 相似文献
