学术界从不同角度对十八届三中全会以来的"三权分置"改革展开了讨论、研究,然而对"三权分置"的界定仍众说纷纭、缺乏共识,其背后潜在的问题与风险亦值得关注。林地是土地的重要组成部分,应坚持集体林地所有权,保护林地,保障林农的利益。但林地使用权"价值饱和"存在权属不清、流转不规范、主体单一等问题。通过"三权分置"制度的改革,对经营主体进行规制,明晰相关的权利属性,规范程序、完善司法救济,可最终实现林地使用权"价值饱和"。 相似文献

我国林地资源丰富,但既往产权不明晰、配套金融服务滞后等因素严重制约了林地资源的保护与开发。随着集体林权制度改革的深化,以林权抵押贷款为重要表现形式的林地综合金融体系开始逐步形成,而其进一步成熟需要构建林业信息服务平台、森林保险业务、林农合作组织等互补配套制度。 相似文献

集体林权制度改革后,农户林地经营规模的大小关系着其收入的高低,并影响着森林经营效率.结合在甘肃省天水市进行的问卷调查,从农户意愿出发,采用统计方法对结果进行分析.研究表明,家庭户均林地面积、家庭劳动力数量和农户的职业是影响农户期望的林地经营面积的重要因素.研究建议相关部门制定有针对性的改革配套政策,促进农户林地经营的适度规模化,以实现农户的增收和林区的和谐发展. 相似文献

农用地土壤污染修复技术是新时代加强农用地土壤污染治理、推进农村地区生态文明建设的有效手段。然而,我国农用地土壤污染修复责任制度存在土地使用权人责任范围语焉不详、政府兜底责任立法缺位以及修复责任追究机制规定散乱的法律困境。对此,结合法学、环境管理学等相关学科内容,同时借鉴域外立法实践与理论经验,主张明确土地使用权人的责任限度、完善政府兜底责任的制度设计以及推动责任追究机制的体系化构建,以期完善我国农用地土壤污染修复责任制度。 相似文献

The decentralization of property rights is the focus of the forest tenure reforms in several developing countries. In China, it was achieved by the launch of a new round of collective forest tenure reform beginning in 2003, which provided farmers with more integrated and secure forestland rights. Drawing on household data collected in Jiangxi province in 2011 and 2013, this paper examines the impacts of households’ recognition of property rights and improved tenure security on forestland rental activities. Our empirical results show that households with higher perceptions of more complete use rights and mortgage rights have a lower probability and intensity of renting‐in land, while households with lower expectations of future forestland redistribution or expropriation are more likely to rent in forestland and more of it. These results imply that the development of a forestland rental market leading to better forest management requires an integrated forestland management approach consisting of decentralization of property rights and village governance. In particular, the central government may further clarify the rights and obligations affiliated to forestland ownership, contractual rights, and management rights; while the village collective may shift from direct intervention in the integrity and security of forestland rights to the supervision and protection of decentralized forestland rights to increase efficiency from the decentralization of property rights. 相似文献

Modeling the Driving Forces of the Land Use and Land Cover Changes Along the Upper Yangtze River of China 总被引:3,自引:1,他引:2
Induced by high population density, rapid but uneven economic growth, and historic resource exploitation, China’s upper Yangtze
basin has witnessed remarkable changes in land use and cover, which have resulted in severe environmental consequences, such
as flooding, soil erosion, and habitat loss. This article examines the causes of land use and land cover change (LUCC) along
the Jinsha River, one primary section of the upper Yangtze, aiming to better understand the human impact on the dynamic LUCC
process and to support necessary policy actions for more sustainable land use and environmental protection. Using a repeated
cross-sectional dataset covering 31 counties over four time periods from 1975 to 2000, we develop a fractional logit model
to empirically determine the effects of socioeconomic and institutional factors on changes for cropland, forestland, and grassland.
It is shown that population expansion, food self-sufficiency, and better market access drove cropland expansion, while industrial
development contributed significantly to the increase of forestland and the decrease of other land uses. Similarly, stable
tenure had a positive effect on forest protection. Moreover, past land use decisions were less significantly influenced by
distorted market signals. We believe that these and other findings carry important policy implications. 相似文献

China’s new Classification-Based Forest Management (CFM) is a two-class system, including Commodity Forest (CoF) and Ecological
Welfare Forest (EWF) lands, so named according to differences in their distinct functions and services. The purposes of CFM
are to improve forestry economic systems, strengthen resource management in a market economy, ease the conflicts between wood
demands and public welfare, and meet the diversified needs for forest services in China. The formative process of China’s
CFM has involved a series of trials and revisions. China’s central government accelerated the reform of CFM in the year 2000
and completed the final version in 2003. CFM was implemented at the provincial level with the aid of subsidies from the central
government. About a quarter of the forestland in China was approved as National EWF lands by the State Forestry Administration
in 2006 and 2007. Logging is prohibited on National EWF lands, and their landowners or managers receive subsidies of about
70 RMB (US$10) per hectare from the central government. CFM represents a new forestry strategy in China and its implementation
inevitably faces challenges in promoting the understanding of forest ecological services, generalizing nationwide criteria
for identifying EWF and CoF lands, setting up forest-specific compensation mechanisms for ecological benefits, enhancing the
knowledge of administrators and the general public about CFM, and sustaining EWF lands under China’s current forestland tenure
system. CFM does, however, offer a viable pathway toward sustainable forest management in China. 相似文献

土地价格是土地价值和权益的具体表现,是调节土地利用的重要手段。地价管理在推进土地有偿使用、优化配置土地资源、促进土地市场建设等方面发挥着重要作用。而现行地价体系比较成熟的只有作为国有土地使用权出让标准的一种基准地价,为适应其它土地权利流转的需要,应建立以土地权利为核心的新型地价体系。 相似文献

随着城市建设和经济发展,划拨土地使用权将进入市场流通。明确划拨土地使用权的财产权性质、合理评估其价格已很必要。与出让土地使用权相比,划拨土地使用权具有特殊性,其价格不宜采用先评估出让土地使用权后扣除出让金的方式评估。作为尝试,可以先评估划拨土地基准地价,用以指导划拨土地价格评估,衡量评估结果。 相似文献

Environmental evaluation of transfer and treatment of excess pig slurry by life cycle assessment 总被引:1,自引:0,他引:1

Slurry management is a central topic in the agronomic and environmental analysis of intensive livestock production systems. The objective of this study is to compare the environmental performance of two scenarios of collective slurry management for the disposal of excess nitrogen from animal manure. The scenarios are the transfer of slurry and its injection to crop land, and the treatment of slurry in a collective biological treatment station. The study is based on a real case in the West of France, where a group of farmers is developing a collective plan for the disposal of almost 7000 m(3) of excess pig slurry. The evaluation is carried out by Life Cycle Assessment, where emissions and resource consumption are quantified and aggregated into four environmental impact categories: eutrophication, acidification, climate change, and non-renewable energy use. Ammonia emitted is the most important contributor to acidification and eutrophication, while methane contributes most to climate change. Both ammonia and methane are mostly emitted during the storage of slurry and, in the case of the treatment scenario, also during composting the solid fraction of the slurry. The two management strategies are similar with respect to climate change, whereas eutrophication and acidification are twice as large for treatment relative to transfer. Electricity needed for the treatment process is the main contributor to non-renewable energy use for the treatment scenario, while the transfer scenario represents a net energy saving, as energy saved by the reduction of mineral fertiliser use more than compensates for the energy needed for transport and injection of slurry. The overall environmental performance of transfer is better than that of treatment, as it involves less acidification, eutrophication and non-renewable energy use. The method employed and the results obtained in this study can provide elements for a transparent discussion of the advantages and disadvantages of contrasting excess slurry management scenarios as well as the identification of the main aspects determining their environmental performance. 相似文献
