我国低碳发展面临的挑战和机遇

低碳发展与转变发展方式高度一致。我国温室气体排放强度已得到一定程度的控制,但在自主创新能力、能源发展战略、森林资源发展和湿地保护诸方面,仍面临着严峻挑战,经济增长与二氧化碳控制之间的矛盾十分突出。我们应立足国情,以节约能源、优化能源结构、增强碳汇为重点,以科技进步和制度创新为动力,在工业化完成阶段尽快从相对减排走向绝对减排。     

新形势下中国林产品贸易的困境与对策探讨

近年来,国际环保主义的盛行和消费者环保意识的提高,不仅催生了以森林认证与产销监管链认证为代表的绿色贸易条件,也促使各主要原木生产国采取各种政策限制木材等原材的出口,美国也修订了《雷斯法案》对贸易中的非法采伐进行限制。林产品贸易所面临的国际环境更加复杂多变。本研究从贸易模式、出口集中度、产业集中度三个角度剖析了中国林产品贸易面临的困境,并提出了相应的对策。     

Dynamic land use and land cover changes and their effect on forest resources in a coastal village of Matemwe,Zanzibar, Tanzania

Recent land cover change estimates show overall decline of tropical forests at the regional and global scales caused by multiple social, cultural and economic factors. There is an overall concern on the prevailing land use practices, such as shifting cultivation and extraction of forest materials as agents of forests losses, but also new, emerging land uses are threatening tropical forests. Understanding of the long-term development and driving forces of forest changes are needed, especially at local levels where many decisions on forest policies and land uses are made. This paper addresses the importance of such information for improved estimates of forest dynamics by studying local level land cover and land use changes during the last 50–70 years in the Eastern African tropical island of Zanzibar, Tanzania. The paper discusses the role of traditional and new land uses mainly subsistence farming, tourism and government interference through tree planting, in the long-term development of the forests at the village level. The material for the study is gathered from the interpretation of archival maps and aerial photographs combined with contemporary digital aerial photographs. The analyses are based on the mapping, spatial sampling and spatio-temporal change trajectory analysis (LCTA) of forest land cover, forest land uses and settlement patterns with GIS and statistics. Six distinct forest land cover change trajectories were identified and these illustrate dynamic and heterogeneous nature of the forests. Closed forest cover has dominated throughout due to cyclical land use patterns, but over 70% of the land area has been continuously transforming between closed, semi-open and open land cover conditions. Land use turnover rates indicate that hardly any forest areas are left untouched from the forces, which remove and re-establish forest vegetation in the long run. Land cover and land use change trajectories are spatially fragmented in the studied landscape. Majority of forest loss-gain dynamics is caused by shifting cultivation, while forest losses are most dramatic along the coast, where traditional and new land uses meet and land uses pressures are highest. The study suggests that landscape change trajectory analyses, where contemporary and historical information on land uses and land cover changes are spatially linked, can provide valuable aspects into local level forest land use planning and management strategies. For the case study, the findings suggest the following key forest management strategies for consideration: (1) establishment of a protected forest/scrubland in participation with the local stakeholders, especially the farmers, (2) promotion of areas for permanent agricultural practices, while simultaneously introducing management controls in the traditional slash-and-burn farming areas, and (3) promoting new livelihood opportunities for the farmers, who have traditionally been dependent on forest resources, meanwhile introducing alternatives for fuel wood for cooking.     

我国地勘市场主体建设

在经济社会快速发展的条件下,我国地勘市场面临着巨大的历史机遇,如何把握我国地勘市场的发展现状,应在总结一般经验的基础上,进一步分析我国地勘市场主体建设的必要性与可行性。我国地勘主体体系建设的雏形已经形成。今后我国地勘市场主体建设的基本策略应是,在地勘单位建立现代企业制度,以矿业权为依托推进现有地勘单位战略重组,优化地勘单位资本结构,更新地质勘探装备,明晰产权,完善社会保障体系,优化人才激励机制、人才引进机制,重视对地质资料的保护和控制。     

新媒体时代大学生思想政治教育面临的挑战及对策

随着科技日新月异,新媒体的广泛传播与应用成为社会的主潮流,尤其对当代大学生的学习与生活产生一定影响。新媒体环境下,知识传播呈现出多样性、开放性的特点,大学生获取内容的方式愈发多元化与自由化。同时,传统的思想政治教育不断受到挑战,大学生对于陈旧、平淡的思想政治教育的兴趣逐渐缺失。新媒体的出现吸引了大学生的关注,是具有创新性与时代性的发展。但随着新媒体的革新,大学生在潜移默化中树立了不同的“三观”,使其思想文化与道德素质都发生了巨大改变。因此,在新媒体广泛应用的时代,有效利用新媒体开展大学生的思想政治教育是非常必要的。     

Challenges faced by world tourism cities – London’s perspective

World tourism cities perform multiple functions and exhibit various characteristics that influence tourism development within their boundaries. They are the main gateway for tourists visiting a country and their success has a direct impact on the visitor economy of that destination. London, the focus of this research, has been one of the world’s top tourism cities for many years, and a key gateway for domestic and international visitors. But despite the important role tourism plays in the economy of the city, there is limited research on the development of this activity in the capital. Using London as an exploratory case study, this paper contributes to better understanding the challenges faced by policy makers when planning and managing tourism in world cities. The adopted research method offers the advantage of gathering insightful information using multiple data collection techniques. Examining this new evidence contributes to expanding the knowledge on the particularities of tourism development in one of the top world cities, which could help policy makers in their efforts to better prepare for potential challenges faced by these complex but important destinations.     

新旧农业社会化服务组织协同制度的路径研究

随着整个国家经济社会发展,农业生产中出现了各种提供社会化劳动服务的新型服务合作社。新型服务社与原来的社会化服务组织如采取协同制度,整个社会福利将得到帕累托改进。制度经济学的理论可说明新旧服务组织的协同制度变迁路径。在制度变迁的初始阶段新型服务社是第一行动集团,潜在的利益推动制度变迁;地方政府是诱致性制度变迁的突破口,其发现潜在收益并转换角色,制度变迁表现为中间扩散;中央政府成为主导,继续推动制度变迁。推进协同制度应尊重服务社的选择,体制内的原有服务组织可以服务社作为新的平台提供服务,地方政府加强对体制内的原有服务组织考核,中央政府重塑农业社会化服务体系。     

EU Policies on Bioenergy and their Potential Clash with the WTO

The paper outlines EU policy on bioenergy, including biofuels, in the context of its policy initiatives to promote renewable energy to combat greenhouse gas emissions and climate change. The EU’s Member States are responsible for implementing EU policy: thus, the UK’s Renewables Obligation on electricity suppliers and its Renewable Transport Fuel Obligation and road‐fuel tax rebates are examined. It is unlikely that EU policy is in conflict with the WTO Agreement on Agriculture or that on Subsidies and Countervailing Measures, but its provisions on environmental sustainability criteria could be problematic.     

Agriculture and global climate stabilization: a public good analysis

The stabilization of global climate presents one of the most complex problems in public good provision the world has faced. Continuation of “business as usual” policies, leading to warming of more than 2 degrees over the next year, will produce significant damage to agricultural systems and catastrophic damage to the natural ecosystems that ultimately support agriculture. The best solution to the public goods problem is a “contract and converge” agreement in which the ultimate outcome is a common global entitlement to CO₂ emissions per person.
