新中国70年生态环境建设发展的艰难历程与辉煌成就

中国的生态环境建设,经历了新中国建立之初生产力低下的农耕文明、改革开放后的工业文明、迈向生态文明的三大阶段,每个阶段都有自身的特质、挑战、应对和成效。从1949年到改革开放前,中国整体上表现为农耕文明特征,自然灾害频发、粮食生产短缺、城市化水平低下。为了跳出\"马尔萨斯陷阱\",新中国的缔造者带领人民治理水患,兴修水利,拓荒垦殖,问题得到缓解但没有得到解决,贫困落后依然,没能彻底摆脱\"马尔萨斯魔咒\"。改革开放后,工业化快速推进,城市化加速发展,使农民得以从土地中解放出来,极大地提升了劳动生产力;同时也使土地得以从农民手中部分释放出来,不仅大幅提升了土地资源价值,也使土地得以休养生息自我生态修复。虽然快速的工业化、城市化进程大幅提升了生产力、积累了巨量的物质财富,但是进入21世纪以来,中国的发展逼近工业文明的生态红线、环境底线和资源上线,可持续发展挑战不断凸显。2010年后,中国全面启动生态保护、污染控制和资源节约的转型发展进程,高质量、大力度建设生态文明,推进人与自然的和谐发展。     

论民国时期河南灾荒的社会成因

民国年间河南灾荒现象异常突出，虽与当时整体气候背景及河南特殊的地理特征相关，但灾荒背后的社会原因更应引起我们的关注。其主要表现为：一、社会经济乏力，百姓抗灾能力低；二、政治腐败，体现在政府的赋税名目繁多、政府官员失职渎职以及挪用、贪污河防公款等几个方面；三、战争与灾荒；四、帝国主义列强对中国的残酷掠夺。     

Policy implementation of the Republic Act (RA) No. 9003 in the Philippines: A case study of Cebu city

Municipal Solid Waste Management (MSWM) is considered to be one of the most serious environmental issues in the Philippines. The annual waste generation was estimated at 10.6 million tonnes in 2012 and this is expected to double in 2025. The Republic Act (RA) No. 9003, widely known as the Ecological Solid Waste Management Act of 2000, provides the required policy framework, institutional mechanisms and mandate to the Local Government Units (LGUs) to achieve 25% waste reduction target through establishing an integrated solid waste management plan based on the 3Rs (reduce, reuse and recycling). Although the initial impact of the LGUs is still very limited in implementing the national mandate, this article highlights the successful experiences of Cebu, the second largest city in the Philippines, in reducing its MSW generation by more than 30% in the past three years. This study also explores the implementation process, innovative actions taken by the Cebu City Government in implementing the national mandate at local level and identifies the factors that influence the policy implementation. The findings suggest that the impacts of the national mandate can be achieved if the LGUs have the high degree of political commitment, planning and development of effective local strategies in a collaborative manner to meet with local conditions, partnership building with other stakeholders, capacity development, adequate financing and incentives, and in the close monitoring and evaluation of performance.     

而今迈步从头越——《安全生产法》征求意见稿学习体会和修改建议

首先分析了我国《安全生产法》的发展沿革,且认真学习了目前发布的《安全生产法》征求意见稿,归纳了征求意见稿还应实现四个重点突破:必须体现以人为本的执政理念;职业危害防治应列为《安全生产法》的重要条款之一;安全生产执法监察应与公共安全及行政管理分离;应对工伤保险预防机制作出明确要求。此外,建议通过《安全生产法》的进一步修订实现我国安全生产的制度化建设:建议逐步建立安全生产分级监察管理体制;推进风险管理制度,对企业实行风险分级与分级监管;逐步提出建立安全生产监察员专业化制度;建立与国际接轨的生产安全事故统计报告系统;强化城市建设土地使用规划的风险管理和安全许可;生产安全事故应急管理应强化应急准备工作;建立独立生产安全事故调查机构和公开公正调查程序;应在《安全生产法》中明确"安全生产委员会"的组织形式和功能;生产安全事故责任追究应与激励政策相结合。     

A tale of ‘fat cats’ and ‘stupid activists’: contested values,governance and reflexivity in the brno railway station controversy

ABSTRACT

The article explores one of the biggest controversies over sustainability in modern Czech history, a protracted conflict over whether the Brno railway station should be re-built in a new location. By examining the language of the interaction between a ‘modernizing discourse’ and a ‘sustainability discourse’, the article highlights reflexivity as analytic enterprise that bares the governance dimension of policy conflicts. The reflexive analysis focuses on how actors justify their positions, how they distinguish themselves from their opponents and how they express trust in their own group. It reveals that both discourses are not only related to the re-location issue per se, but that they entail contested notions of legitimate knowledge and modes of governance. Since such power contest is common in sustainability controversies, the reflexive analysis suggests a novel analytical agenda for addressing policy conflicts in sustainability issues.     

CHANGES IN WATER POLICY IN THE PEOPLE'S REPUBLIC OF CHINA1

ABSTRACT: Ideology has predisposed the People's Republic of China against the use of prices to allocate water. Prolonged drought in north China has made the Chinese more aware of their unfavorable water resource inventory and the expense of expanding supply. Therefore, as part of the economic liberalization commenced since the death of Mao Zedong, China has started to make more active use of pricing to regulate demand and reduce the need for supply expansion.     

论民初我国救灾之主要特征

民国初年我国救灾的主要特征有三:一是救灾主体多元化,这可从阶层、国籍、职业、身份等方面看出,总体上又可划分为政府和社会力量两个方面。至于救灾效能,无论是政府还是社会救济力量均存在着或多或少的局限性。二是短效机制占主导,这可从救灾因素之临设性、救灾甚于防灾两点看出。三是社会过渡性彰显,无论是思想,还是机构、制度,都呈现出明显的新旧交错性,即社会过渡性。     

Removal of trace elements in three horizontal sub-surface flow constructed wetlands in the Czech Republic

Between March 2006 and June 2008 removal of 34 trace elements was measured on a monthly basis at three horizontal-flow constructed wetlands in the Czech Republic designed to treat municipal wastewater. In general, the results indicated a very wide range of removal efficiencies among studied elements. The highest degree of removal (average of 90%) was found for aluminum. High average removal was also recorded for zinc (78%). Elements removed in the range of 50-75% were uranium, antimony, copper, lead, molybdenum, chromium, barium, iron and gallium. Removal of cadmium, tin, mercury, silver, selenium and nickel varied between 25 and 50%. Low retention (0-25%) was observed for vanadium, lithium, boron, cobalt and strontium. There were two elements (manganese and arsenic) for which average outflow concentrations were higher compared to inflow concentrations. Reduced manganese compounds are very soluble and therefore they are washed out under anaerobic conditions.
