Previous research on European forestry service markets is scarce and mainly focused on analysing external market environment and modelling of timber selling behaviour of non-industrial forest owners (NIPFs). In this study, we aim to create a broader understanding about business perspectives of forestry service markets covering the whole array of market and institutional based services offered to the NIPFs in case of Finland. The more specific empirical objective of the paper is to describe market drivers and underlying challenges in existing and potential service business models based on the concepts of service-dominant logic and dynamic capabilities. Using a qualitative approach and 22 thematic expert interviews in service organisations, we strive to analyse the drivers and opportunities for creating new services within the NIPF market and also build insight in possible barriers for new service value creation. According to our results, the ongoing structural changes offer new opportunities to change traditional mindsets and search for new types of offerings that support the renewal of this traditional forestry sector. As one of the major barriers for new innovations we identified the dominant role of established organisations securing their current positions, mainly driven by the forest industry timber procurement needs. From a managerial perspective, the changing institutional base of the current service organisations may facilitate new innovative business start-ups in addition to enhancing the strategic capabilities and competitiveness of the established firms in Finnish forestry sector. 相似文献

分析了集体林地使用权流转过程中各利益相关者的博弈关系,基于经典博弈理论构建了林管部门、村干部、农户3方动态博弈模型对其博弈关系加以分析,研究结果表明:林地使用权流转的最优均衡解为林管部门鼓励林地使用权流转,村干部积极配合流转,农户积极参与流转.集体林地使用权流转是林管部门、村集体、流转农户等多元利益主体问利益关系动态博弈的过程;为激励和促进林地使用权流转,需建立公平有效的流转利益分配及奖惩机制,进一步深化林权制度改革和完善配套改革,以及完善林地使用权流转服务体系. 相似文献

以南平市顺昌县阔叶林地小班资料结合现行市场有关技术经济指标,利用Richards方程拟合出胸径、树高、蓄积的生长方程,分不同立地类型在不同投资收益率的情况下运用林地期望价法计算阔叶林林地价值,对其逐年支付的合理地租进行分析研究。研究结果表明,按林地期望价法计算的阔叶林林地价值要高于现阶段南平地区经营阔叶树的地租水平。因此,应适当提高现行林地地租水平,以提高阔叶树经营者的积极性。 相似文献

作为陆地生态系统的主体,森林生态系统的碳循环与碳蓄积对研究陆地生态系统碳循环起着重要作用.生物量、生产力、土壤有机质以及凋落物量及其分解等相互关系决定了森林生态系统的碳库量和碳交换量.本文简单地介绍了在碳蓄积研究中森林生物量和生产力的几种研究方法,并对研究过程中的问题(大尺度生物量的精确估算,地下生物量的研究,森林生态系统土壤碳库估算)进行了探讨. 相似文献

Internationally, conservation easements are increasingly popular land management tools for private landowners, government
agencies and non-governmental organizations seeking to preserve forests and other natural settings. This paper reports a study
of the design and use of conservation easements by organizations and public agencies in the USA. More than 355 conservation
organizations and 16 state agencies holding at least 3,598 forestland easements were identified. Demonstrated shortfalls in
baseline forest inventories, record keeping, and professionally-developed management plans were evident on working forest
easements. Failure to address these shortcomings runs the risk of jeopardizing the legitimacy of the easement approach even
where favorable legal and tax conditions exist. Management restrictions varied broadly, with a minority of respondents prohibiting
such techniques as clearcutting and salvage logging. Concerns for the use of chemicals, best management practices, and streamside
management zones were commonly reflected in easement language, whereas logging road design and the cultivation of old-growth
conditions remain largely undeveloped. Implications from the US experience, where easements are relatively well-developed,
highlights the need for professional forestry advice—particularly for non-industrial or small-scale forest owners—in both
easement development and implementation, the need for careful planning, and the need to carefully consider the respective
goals of the forest landowners in crafting the easement documents. In the cases of developing nations, consideration of the
differing needs of landowners may require increased flexibility in management documents. 相似文献

基于TM数据的森林植物碳储量估测方法研究 总被引:4,自引:0,他引:4
以广东省第六次森林资源连续清查样地数据为基础,根据TM数据及其非线性组合的光谱信息,结合地学信息及林分信息,建立了森林植物碳储量估测的多元线性回归方程及神经网络模型。分析结果表明,神经网络模型的估测精度高于回归模型估测精度,但用它们估测落实到样地的森林植物碳储量误差仍然较大,还不能满足样地调查精度的要求。 相似文献

利用旌德县第8次森林资源二类调查数据,采取建立数学模型的方法分析了该县的乔木林总量及其年龄结构,依据建立的不同森林类型生物量和蓄积量之间的回归方程,估算了全县乔木林的碳储量及碳密度。结果表明:(1)旌德县乔木林总面积50190.7 hm2,乔木林总蓄积3624337 m3,以庙首镇森林面积最大。(2)乔木树种以杉类、硬阔和松类的面积和蓄积最大,乔木林的年龄结构较为合理;(3)乔木林生物量为118.18万t,乔木林碳储量为591485.20 t,碳密度为11.78 t/hm2,不同森林类型碳密度差异很大,以柏类的碳密度最大,达到27.63 t/hm2,软阔、硬阔林的碳密度较小,仅为0.73 t/hm2.和0.17 t/hm2.。因此,在实施各重点造林工程的同时加强中幼林抚育管理,提升现有林质量,促进林木生长,有效增加单位面积蓄积量,将会使旌德县森林的碳汇能力进一步提高。 相似文献
