轨道交通沿线土地溢价归公的政策与实践——以东莞市为例     

林雄斌  余筱琪  陈伟劲 《热带地理》2019,39(5):732-741

轨道交通周边土地开发和溢价归公有助于缓解城市财政压力,推动公交都市建设。结合国外实施溢价归公的政策和实践模式,以东莞市为例,在资料收集、政策分析、文本和案例解读的基础上,探讨了中国城市政府在规划和建设轨道交通中,以土地溢价归公反哺轨道交通融资的政策安排和实施效果。结果表明：1）溢价归公的本质是以特定方式实现正外部效应的内部化,由于土地制度和税收体系的差异,欧美地区溢价归公主要依赖多样化的土地税收体系,而中国城市的实践主要借鉴了“轨道+物业”的联合开发模式;2）东莞市溢价归公策略的形成是综合开发规划编制和审批、沿线土地控制和储备、土地发展权转移、土地增值分配等核心环节有效协调的结果;3）东莞轨道交通沿线土地开发能形成可观的财政收益,潜在土地收益占轨道资金总需求的比例超过20%,但在实施过程中仍面临较大困难。东莞市案例能为其他城市轨道交通融资、土地开发和溢价归公的政策体系编制和有效实施提供一定的参考。  相似文献

近年来,福建海洋工程装备产业进步显著,初步形成了以港口装卸、海上起重机、海底铺管、大型汽车滚装船等传统装备为主导的制造基地;同时,海水淡化核心装备、海洋防腐材料、水下作业机器人、游艇装备等新兴产业也取得了快速发展,但仍存在产业基础薄弱、整体产品低端、研发力量小且分散、试验研发平台严重不足等制约"瓶颈"。文章通过现场调研和资料查询分析了福建海洋工程装备产业的发展现状,总结归纳出当前制约产业发展的主要因素,明确发展思路,提出建设具有海西特色的海工装备制造业应发展海洋工程装备的重点领域、编制福建省海洋工程装备中长期发展规划和实施方案、提升海洋工程装备科技创新能力、制定海洋工程装备发展的扶持政策、构建比较完整的重点领域海洋工程装备产业链等对策与建议。  相似文献   

临沂市开展集体建设用地使用权流转的几点思考          下载免费PDF全文

冯连伟 《山东国土资源》2004,20(6):43-47

结合临沂市几年来开展集体建设用地使用权流转的实践和探索,对开展集体建设用地使用权流转的背景、概念及范围进行了论述。认为在计划经济条件下形成的农民集体所有建设用地使用权不能流转的制度已与当前农村经济,特别是小城镇的建设发展严重不适应,允许集体建设用地使用权流转已势在必行。开展集体建设用地使用权流转对保护土地所有者和失地农民的权益,推动小城镇建设健康发展,规范土地市场具有重要意义。  相似文献

征地补偿安置是当前群众反映最强烈并迫切要求解决的问题。要解决该问题必须进行土地征用制度改革．由政府按照市场公平原则向农民集体征购土地，实行统一的土地征购制度。  相似文献   

Fishing industry and related perspectives on the issues raised by no-take marine protected area proposals   总被引：2，自引：2，他引：0  

P.J.S. Jones   《Marine Policy》2008,32(4):749-758

In the face of growing calls for no-take marine protected areas (NTMPAs), the views of fishing industry representatives in south-west (SW) England on related issues are analysed. Only 23% thought NTMPAs were the way forward and a range of concerns were expressed, e.g. that the ‘terrestrial’ protected areas approach and related biodiversity conservation objectives will be extended to the seas, and that fish yield reductions from the loss of access to NTMPAs are very unlikely to be compensated for through spillover/export. Some interesting approaches to ameliorating these concerns emerged, such as being open and honest that NTMPAs are primarily intended to achieve biodiversity conservation benefits, reducing uncertainty concerning the potential for any secondary fisheries spillover/export benefits, justifying NTMPAs on an objective, rational basis rather than on a subjective, precautionary basis, and the quid pro quo streamlining of wider fisheries management approaches. This research reveals a more diverse range of perspectives amongst fishing industry representatives on the issues raised by NTMPA proposals than is often assumed.  相似文献   

Decoupling of stalagmite-derived Asian summer monsoon records from North Atlantic temperature change during marine oxygen isotope stage 5d   总被引：2，自引：0，他引：2

The Asian monsoon is an important component of the global climate system. Seasonal variations in wind, rainfall, and temperature associated with the Asian monsoon systems affect a vast expanse of tropical and subtropical Asia. Speleothem-derived summer monsoon variation in East Asia was previously found to be closely associated with millennial-scale change in temperature in the North Atlantic region between 75 and 10 ka. New evidence recovered from East Asia, however, suggests that the teleconnection between summer monsoon in East Asia and temperature change in the North Atlantic region may have significantly reduced during 120 to ~ 110 ka, a period directly after the full last interglaciation and corresponding roughly to marine oxygen isotope stage 5d. This reduction may be due to the low ice volume in the North Hemisphere at that time, which makes the millennial-scale change in temperature in the North Atlantic region less effective in influencing the Asian summer monsoon. This is important for investigating the mechanisms controlling the Asian summer monsoon and the paleoclimatic teleconnection between East Asia and the North Atlantic region, and for predicting monsoon-associated precipitation in East Asia under a global-warming trend.  相似文献   

Probing the (in)compatibilities of social theory and policy relevance in Piers Blaikie’s political ecology     

Roderick P. Neumann 《Geoforum》2008,39(2):728-735

One of Piers Blaikie’s most important contributions to the development of political ecology is his critique of land and resource conservation policy in the global South. In this paper I trace the development of Blaikie’s ideas about the policy relevance of political ecology, focusing particularly on the challenges posed by the introduction of poststructural social theory into the field. I begin by revisiting Blaikie’s earlier critiques of environment and development policy. This will provide the departure point to explore how his thinking on the relationship of theory and policy and of academic and development practices has evolved in subsequent writings. I have invented two personas, “early Blaikie” and “late Blaikie”, to facilitate this task. Second, I want to probe some of the challenges that late Blaikie presents for doing political ecology research, to some extent by pitting early Blaikie against late Blaikie and letting them hash it out. Third, I turn to my own and others’ research and consultation experiences as a way to examine the possibilities for reconciling theoretically driven critiques with policy relevant research.  相似文献   

UV-B辐射对海洋微藻抗氧化系统的影响   总被引：4，自引：1，他引：4  

于娟  唐学玺  李永祺  王晨  刘文明 《海洋科学》2002,26(12):49-53

研究了UV－B辐射对两种海洋微藻－小新月菱形藻（Ntzschia closterlum)和亚心形扁藻（Platymonas subcordiforming)的抗氧化系统的影响。结果表明：在本实验的辐射剂量范围内，随着UV－B辐射剂量的增强，两种藻的抗氧化防御系统的非酶性组分还原型谷胱甘肽（GSH）和类胡萝卜素（CAR）的含量随之下降；抗氧化防御系统的酶性组分超氧化歧化酶（SOD）和过氧化氢酶（CAT）的活性逐渐降低。加入外源性抗氧化剂GSH可减轻UV－B辐射对藻的伤害。分析表明海洋微藻的UV－B伤害是由于抗氧化防御系统遭到破坏而导致活性氧积累的结果。  相似文献

1986年11月—1987年5月,在中国第三次南极考察和环球科学考察期间,收集了58个海洋气溶胶样品,采用中子活化法分析了Al,V,Mn,I,Br,Mg,Na,Cl等元素。应用因子分析、回归分析和富集因子分析对气溶胶中元素进行分类、定量评估和来源判别,讨论不同来源元素的特征,计算各主要来源的贡献分量。结果表明,海洋气溶胶中Al的99.99％是来自陆源地壳风化物,Na的99.2％。和Cl的99.99％是来自海水,V的91.4％。来自陆源污染物。因此,Al可作为海洋气溶胶中陆源地壳风化物的示踪元素,Na和Cl可作为海水源示踪元素,非地壳源的V则可选择为陆源污染物的示踪元素。  相似文献
