采伐限额管理制度对农户抚育采伐行为的影响分析 总被引:3,自引:0,他引:3
依据农户理性人假设和实际调研数据,深入地分析了森林采伐限额管理制度对农户抚育采伐行为的影响,研究结论认为:森林采伐限额管理制度不影响农户抚育采伐决策,农户抚育采伐决策主要受到抚育采伐技术规程、抚育采伐的木材生产成本和短小材和小径材市场价格的影响,在抚育采伐技术规程的严格约束下,农户往往会推迟抚育采伐的开始期,并在采伐木的选择上做出"砍中留大留小"的决策,这说明严格的抚育采伐技术规程并未达到提高森林质量、促进森林资源增长的政策设计初衷,政府需要对森林抚育采伐的技术规程进行调整。 相似文献

总结回顾了江西省十一五期间森林采伐管理历程,江西省坚持森林采伐限额不突破,确保林农合法权益得到落实,惩处乱砍滥伐行为,加强林业部门能力建设。通过对全省11个设区市及26个县的调查认为:现行森林采伐管理政策滞后,受采伐限额制约经营者林木处置权难以落实,林木采伐管理对象多监管难以到位。为此提出了做好今后5年森林采伐管理工作的对策措施。 相似文献

浅山区森林采伐木材生产成本核算管理的研究 总被引:2,自引:0,他引:2
森林采伐木材成本核算管理工作是林业生产中一项重要的工作内容。我国木材成本的核算,是建国初期按苏联的核算模式学来的。木材工业苏联称之为木材采运工业,和煤炭工业一样按采掘工业进行管理,因此在木材成本中只有木材在采伐和运输过程中发生的费用。作业流程为:林木采伐、打枝、堆枝、造材、吊卯、集材、归楞、运材(运至贮木场)、归楞、清理等10道作业程序。此种作业程序一直延续到20世纪90年代中期。根据多年来的木材成本核算调查,以往的木材成本费用支出如下表:木兰县林业局1994年-1998年天然林木材生产成本核算调查表从以上木材生产成… 相似文献

森林采伐限额管理制度能否起到保护森林资源的作用:一个文献综述 总被引:1,自引:0,他引:1
《中国农村观察》2016,(2)
已有研究从理论和实证两个方面对森林采伐限额管理制度和森林资源保护的关系进行了详尽且富有意义的探讨。多数研究发现,采伐限额管理制度对森林资源的保护作用不明显,不仅无法遏制大面积森林采伐,反而阻碍了森林经营者的造林管护行为。已有文献为进一步研究采伐限额管理制度对森林资源的保护作用提供了极有价值的线索,但仍存在影响机理分析不够全面、对森林资源保护效果的评价缺乏动态性和系统性、研究内容较为狭隘以及计量方法不够严谨等问题。因此,未来研究采伐限额管理制度与森林资源保护的关系应从如下几个方面改进:1深入分析森林采伐限额管理制度对森林资源保护的影响机制;2关注森林采伐限额管理制度的变迁及构成对森林资源保护的作用;3应将森林碳汇量等森林生态价值作为森林资源的组成部分,并探索森林采伐限额管理制度对森林生态效用的影响;4在计量分析中应注意制度测度偏误、模型变量内生性以及异方差性、截面自相关等问题。 相似文献

分析采伐限额制度的合理性,在这个前提下,探讨如何获得经济收益的最大化。林业资源的经济收益取决于市场状况的同时也受到它本身特性的约束,这里市场状况包括总体用材林限额决定的供给量和整体市场的需求量,林业资源特性包括林业用地的限制、木材培育费用和木材的生长期限。通过将市场状况和林业资源本身特点的结合,得出在不同的情况下如何使用和分配用材林采伐限额,在单位内转结的有效性或者在单位间转让的可能性,以实现在采伐限额制度下取得林业资源经济收益最大化。 相似文献

基于前景理论构建包含监管部门、林业主管部门和森林资源经营者的三方博弈模型,对森林采伐限额管理制度执行过程中存在以配置采伐限额权力与金钱交换为特征的权力寻租行为进行分析。结果表明:监管部门是否进行监管取决于对寻租概率和监管成功概率的主观判断,林业主管部门与森林资源经营者是否寻租取决于对寻租行为的惩罚力度、寻租行为的租金和寻租行为额外收益的主观判断,还受制于前景理论中厌恶损失效应程度、边际递减敏感性程度的影响。未来可从完善森林采伐限额管理制度、建立健全监管机制、提升林业主管部门执业规范,加强职业道德建设3个方面降低寻租行为发生的可能性,准确科学地防范寻租行为。 相似文献

以林业栽培技术服务为例,基于1342份实地调研数据运用IVProbit和倾向得分匹配(PSM)模型考察林业社会化服务对林地规模经营行为影响的程度和方向。结果表明:林业栽培技术服务能显著促进农户林地规模经营行为,但对不同林种的影响程度差异较大;林业工作站或技术推广站主导的栽培技术服务在促进农户规模化经营行为中承担主要角色,反映出林业社会化服务的市场化进程相对缓慢,市场化主体供应的服务未能很好地满足农户林地规模化经营的需求。因此,政府应当大力发展林业社会化服务,完善林业生产服务体系,扩大服务的受众面;培育多元化社会化服务主体,推动林业社会化服务专业化和精准化发展。 相似文献

采用访谈和问卷调查相结合的方式,选择河北省3个平原试点县的林农作为调查对象,就林农对现行林木采伐管理改革的认知、评价和意愿进行考察与分析,得出了以下主要结论:第一,试点县对森林采伐管理改革政策内容的宣传不够,大部分林农对最新的政策不清楚;第二,绝大多数林农对国家实施采伐限额制度改革的目的比较清楚;第三,林木采伐管理改革得到了林农的普遍支持。最后试图在尊重林农意愿的基础上,对完善非公有制林木采伐管理改革提出了合理化建议。 相似文献

We examine the intensity of harvesting decision by non-industrial landowners at the lowest price offer they deem acceptable, using a multiple bounded discrete choice stated preference approach that draws upon and connects two subfields of forestry, one identifying characteristics of landowners important to past harvesting or reforestation decisions, and another proposing how landowners evaluate price offers for forest harvesting decisions. Variables important to harvest intensity choices when the landowners find an acceptable price have only been considered for those landowners who actually have participated in harvesting markets, whereas here we examine the behavior of these individuals as well as those who are on the margin (i.e., have not harvested at prevailing current or past market prices). We show that harvest intensity depends critically on the extent of urbanization, indicated by the presence of structures on a parcel as well as forested tract size, along with landowner characteristics such as absenteeism and length of ownership. The results are useful for understanding the timber management behavior for a majority of landowners who may not harvest at prevailing prices, but may participate should prices reach a level acceptable to them, where this level is determined by individual preferences for standing timber resources. 相似文献

In an effort to increase wood production and mitigate environmental problems, agro-forestry practices have emerged as a viable strategy in the Northern Plains of China, where one popular form of the agro-forestry system consists of fast-growing and high-yield plantation of poplar (populus) trees and the underwood planting of button mushroom (Agaricus bisporous). This paper examines adaptive management decision-making with stochastic dynamic programming under risk of timber price. Under the assumption of risk neutral preferences of the investors, the results suggest that the reservation price strategy remains optimal for the harvesting decision of agro-forests: when the timber price is higher than the reservation price, poplar trees should be harvested to end agro-forestry; otherwise, the trees should be retained. Numerical results are presented for sample agro-forest stands, which show that, with underwood planting, the reservation price for timber harvesting will be higher than that in pure forest. 相似文献

基于2016年7~8月南方集体林区福建省三明、南平、龙岩地区512个样本农户的微观抽样调查数据,运用Probit模型分析林地转入户资源禀赋、经营方式对其林地流入行为的影响,并通过平均边际效应测其影响程度。结果表明:第一,资源禀赋中林地面积、林业劳动力数量、社会关系均正向显著影响农户林地流入行为,家庭总收入负向显著影响农户林地流入行为;第二,经营方式中营林形式、单位面积资金投入对其林地流入行为均有显著正向影响。鉴于此,为了更好地实现"森林资源增长"和"农户增收"双重目标,在集体林权制度改革中,政府应通过加快林地流转交易平台建设、鼓励"联户经营+集约化"经营方式、培育中青年林业经营主体及引导木材市场价格健康有序发展等方式来推进林地流转进程。 相似文献

Although the regulations are imperfectly enforced, logging firms in the Brazilian Amazon are subject to forest management regulations intended to reduce environmental damage and protect future forest productivity. Additionally, voluntary best practices firms adopt to achieve environmental performance that exceed regulatory requirements are largely limited to reduced impact logging (RIL) systems that reduce harvest damage relative to conventional logging systems used by a large majority of firms in the region. Existing regulations combined with best practices may not be adequate to ensure sustained yields. This inadequacy is an important issue as Brazil implements an ambitious program of forest concessions on public lands. We analyze the profitability and environmental outcomes of best logging practices and proposed sustainability requirements. We propose two operational definitions of sustainability (the first focusing on sustaining stand-level timber volumes and the other focusing on sustaining species-level volumes within the stand) based on sustaining timber inventories across cutting cycles rather than on sustaining overall harvest yields. RIL is shown to be profitable for loggers and increase the timber available for future harvests. While volume predicted to be available for the second and third harvests are significantly lower than the available timber in the unlogged forest, the second and third harvests are projected to be profitable and have the potential for sustainability despite high opportunity costs. However, as harvesting is repeated into the future, results show the composition of the harvest shifts from higher-value shade-tolerant and emergent species toward a greater reliance on longer-lived, lower-value pioneer species. This shift may create pressure to expand the forest base under management in order to continue to supply high-value species or increase the risk of timber trespass in conservation units and areas under community or indigenous management. 相似文献
