基于森林可持续经营的林业碳汇开发路径初探
——以乌尔旗汉林业局为例 总被引:1,自引:0,他引:1
乌尔旗汉林业局可持续经营碳汇试点研究项目是自治区2016年应对气候变化及低碳发展科研课题之一。该项目仅选取森林可持续经营试点中人工林落叶松中龄林林分,通过森林经营类碳汇方法学在可持续经营中的运用,探索森林可持续经营中森林固碳功能提升的具体措施。研究表明,影响森林碳储量及其稳定性的主要因子是森林结构、合理的经营密度、森林公顷蓄积量等质量指标,而经营密度是核心因子。本项目通过不同抚育强度措施,找到森林结构和密度的最佳调整值,研究结论是:在中龄林范围内,基线株数密度平均为3225株/hm^2,时,最佳抚育强度为20%,应该在合理的经营间隔期内进行后续抚育经营;基线株数密度平均为2417株/hm^2时,最佳抚育强度为20%,在合理的间隔期内进行后续抚育经营;基线株数密度平均为1842株/hm^2,时,最佳抚育强度为10%o应打破现行落叶松人工林龄组限制,通过后续监测,找到落叶松人工林年生长率低于2%的数量成熟林龄,在林分数量成熟时,及时均匀伐除部分林木,林下栽植其他幼龄喜阴树种,营造复层异龄混交林,以改善林分内林木生长发育的环境,提髙林分稳定性,促进林地生产力提升,使森林多重效益得到提高,最终实现林分碳储量的最大化。经专家论证,该项目填补了内蒙古大兴安岭林区自主开发森林经营碳汇项目的空白。 相似文献

森林资源是我国重要的自然资源之一,不仅在生态平衡维护中起到重要作用,还在我国经济发展中占据重要地位。近年来,国家对森林资源培育与经营管理工作的重视程度不断提升,并出台了系列政策,支持和促进林业产业发展。而基层森林培育与经营管理,直接影响到森林资源的整体质量。文章结合泸水市老窝镇的实际情况,对基层森林培育与经营管理中存在的问题进行深入分析,并提出一些合理地对策措施,对提升基层森林培育与经营管理水平,实现森林资源的可持续发展具有一定意义。 相似文献

人们往往对马来西亚执行森林管理的方式深感兴趣。首先,大家必须先了解到马来西亚实行君主立宪联邦制,管辖三个地理分区——马来西亚半岛、沙巴以及砂捞越。行政权、司法权以及相关责任由联邦政府与州政府共同承担。然而,13个州政府与联邦直辖区对农业、土地、土壤保护、河流、水,以及森林资源都拥有司法管辖权。 相似文献

随着社会发展对劳动力的需求呈井喷式增长,劳动关系的主体及其利益诉求的多元化导致劳动争议复杂化,日益成为我国社会和企业用工管理不得不考虑的问题。国家先后出台了数量可观的劳动行政法规和规章,各地方也出台了数以万计的劳动类文件,然而法律规章并没有为企业的人力资源管理带来接地气的帮助,劳动争议仍位居社会冲突的排行榜前几位。尤其是随着互联网与新媒体的发展,新型劳动争议更给企业人力资源管理带来挑战。鉴于此,彭振华主编了《互联网与新媒体时代企业用工管理-人力资源法律管理》一书。 相似文献

在经济全球化和国际竞争加剧的背景下,国家在发展的过程中也越来越重视林业保护的重要性。林业资源是地球上的重要资源,对林业的利用可以促进人类的繁荣,提高人类对自然的了解和改造自然的能力,特别是在经济发展下林业的保护对人类的生产和生活产生了重大影响。在国际社会中,各个国家和地区在保护其林业资源方面已十分谨慎,并以法律形式建立了对林业的保护。 相似文献

ABSTRACTAs the role of forests in climate change mitigation is explicitly recognized in the Paris Agreement, the need to enhance the adoption of Sustainable Forest Management (SFM) practices is crucial. Therefore, this paper aims at identifying and evaluating barriers in adopting SFM practices in the context of forest carbon emission reductions. A total of 15 barriers in adopting SFM practices are listed through literature and expert inputs. Using Cameroon as a case study, the listed barriers are then evaluated by experts to determine their relative importance using the Analytical Hierarchy Process (AHP) method. According to our findings, the ‘Regulatory and Legislative frameworks’ barrier category was attributed to the highest importance among other categories, in adopting SFM practices in the forestry sector. ‘Inadequate political will and incentive to enforce regulations’ appears to be the major obstacle in adopting SFM practices in Cameroon. As carbon emission reduction initiatives are being developed, there is need to move from broad to concrete suggestions that will overcome these barriers. However, proper diagnosis is necessary in order to target barriers with the right incentives and enabling conditions that will support carbon programs and projects to deliver effective emission reductions. 相似文献

Abstract It is claimed that reduced emissions from deforestation and forest degradation (REDD) could contribute to sustainable management of forests and enhancement of forest carbon stocks as well as having the potential to deliver significant social and environmental co-benefits (+). From the perspectives of local factors and broader governance issues related to REDD+, this study aims to explore findings related to three crucial elements, commitment, transparency and continuity, implemented jointly with participatory forest management in Tanzania in the case of the REDD+ mechanism. This paper argues that commitment and transparent systems are needed at village level, as well as at the various levels of forest governance and among the donors, in order for REDD+ benefits to be shared equitably at the REDD+ project level. Any REDD+ project should include safeguards that recognise and protect the continuity of multipurpose functions of the forest to local people and avoid dependence on external payments. 相似文献

Reducing Emissions from Deforestation and forest Degradation (REDD+) is a conservation finance instrument based on the payments for ecosystem services model, wherein governments, private landowners, concession holders, and/or communities are compensated for undertaking activities which mitigate greenhouse gas emissions from forest use and land use change. This article reviews the numerous sources for REDD+ finance within the context of total global conservation finance. In 2013, there were approximately 47 REDD+ projects conserving nearly 20 million ha with a total transacted value in carbon offset credits estimated to be US$98.8 million. Scaling up conservation financing instruments, particularly REDD+, is critical to halting tropical deforestation and reversing the trend of global climate change. Although the bulk of REDD+ financing, especially for capacity building efforts, comes from public sector channels, this article discusses five opportunities for private sector firms to support REDD+: a firm can develop their own project; a firm can donate unrestricted funds to a nonprofit organization; a firm can invest in a for-profit firm; a firm can choose to support a particular REDD+ project; or a firm can invest into a dedicated fund. 相似文献
