2000—2014年中国经济系统物质流核算与资源产出率研究

本文利用经济系统物质流分析框架核算了我国2000—2014年的主要物质流、资源产出率等指标。结果表明：① 2000—2014年本地采掘物质量、进口量和本地处置后排放均有较快增长。2011—2014年本地采掘中生物质采掘量逐年稳步增长,非金属矿石和化石燃料采掘量处于下降趋势。本地处置后排放中空气排放物贡献了绝大部分比例并逐年增长,水污染排放物逐年下降。② 2000—2014年人均资源的采掘、投入和消耗量均有大幅增长,2014年人均物质消耗量比2000年增长1倍以上。资源产出率和单位GDP本地采掘、投入物质量处于波动式增长趋势,本地采掘每吨物质所贡献的GDP已连续三年超过资源产出率。③ 2014年中国资源产出率约为欧盟28国平均水平的1/4。2010年我国省级资源产出率差异较大,小部分地区已超过欧盟同期水平,但仍有大部分地区的资源产出率较低,未达到全国平均水平。     

生态文明产权制度的界定、分类及框架研究

生态文明产权制度是生态文明制度体系建设的根基。生态文明产权制度可划分为自然资源产权制度、环境资源产权制度和气候资源产权制度三大类别。自然资源产权制度包含水权、林权、矿权、渔权和能权,环境资源产权制度包含排污权和生态权,气候资源产权制度包含碳排污权和碳汇。在大国责任的国际背景下,生态文明产权可用总量控制是硬性约束,必须以自然、环境和气候资源的产权总量控制为前提,确保全国总体生态水平在可预见的时间达到可控制的范围之内。有效地推进自然、环境和气候资源的初始产权界定,运用生态文明产权价格机制促进生态文明产权交易,并运用生态文明产权保护制度确保初始产权界定、产权交易机制和产权价格机制的顺利推进和开展。形成以产权总量控制为前提,以初始产权的界定和分配为基础,以产权交易机制为手段,以产权价格机制为核心,以产权保护制度为保障生态文明产权制度框架。     

氟化工“三废”的资源化利用

结合我国氟化工行业发展现状,分析了含氟"三废"产生情况及处置方法的最新研究进展,并通过实际工程案例进行论述。氟化工生产过程污染物主要有含氟废气及副产氯化氢、含氟高沸物及含氟污泥等。通过将氯化氢用于工业清洗及制备氯化钙、氯化铝等化学品能够合理消耗副产盐酸。焚烧处理含氟有机废气产生的氟化氢气体经水洗后副产氢氟酸。含氟高沸物通过精馏分离出高沸物组分生产高附加值产品。含氟污泥可制成建筑材料,最优工业化利用途径仍在积极研究中。     

What’s missing from Ostrom? Combining design principles with the theory of sociocultural viability

Since 1990, Elinor Ostrom’s design principles for common property resource (CPR) institutions have been highly influential, offering a counter to pessimistic arguments about resource users’ prospects of cooperating to manage CPRs sustainably. However, the theoretical underpinnings of Ostrom’s theory have been criticised: as unfairly negative towards macro-level interventions; as utilising an overly narrow conceptualisation of rationality; and under appreciative of the role of power. These criticisms are examined using insights drawn from the theory of sociocultural viability (cultural theory, for short), a theory of plural rationality related to context. Utilising the case of Faroese whaling, the research aim is to assess the extent that cultural theory ameliorates criticisms laid at Ostrom’s design principles. It finds that Ostrom’s research trajectory was reaching the limits of methodological individualism’s ability to grasp rational behaviour and suggests the design principles may in effect be integrated with cultural theory.     

Drivers of local people’s participation in sustainable natural resource management: a case study in central Iran

The driving forces behind natural resource management (NRM) vary among countries. Most NRM programmes focus on biophysical drivers such as soil, water and vegetation, with little attention directed towards the nuanced sociocultural and religious drivers of sustainable natural resource management (SNRM) practices. This paper explores those understudied drivers that influence local people’s participation (LPP) in SNRM in Isfahan, Iran. Using a multi-stage stratified sampling method, we selected 200 natural resource experts and natural resource users to complete a questionnaire about their perceptions of SNRM. Results reveal that sociocultural and religious beliefs are the major drivers of SNRM. The results also indicate that subsidiary drivers include: a sense of responsibility towards SNRM; the conviction that natural resources belong to God and should therefore be preserved; participation to preserve natural resources because of training courses and media influence; a long-established custom of preserving natural resources; and the specific impact of environmental television programmes. Demographic analysis finds a significant relationship between educational level and LPP in SNRM. This study’s results therefore suggest that natural resource managers would benefit from a deeper understanding of the local sociocultural and religious contexts that motivate people to participate in SNRM.     

Reconciling local control with appropriate scale in Norwegian moose management

In a landscape of fragmented private ownership, the need to coordinate game management across large areas presents challenges for landowners and public agencies alike. This paper describes how a recent reorganization of moose management in Norway achieves landscape-level planning while maintaining a tradition of local management by hunting teams. These two seemingly contradictory imperatives – coordinating wildlife management across large areas while keeping benefits and control in the hands of local resource users – are resolved through a nesting of management institutions, wherein the state serves a regulatory function and mid-level government (the county) serves to facilitate inter-local cooperation. This paper documents how the system is structured and describes the balance of incentives that enable the system to work. Information was gathered via interviews with staff at the Norwegian Directorate for Nature Management (now called the Norwegian Environment Agency), with wildlife management officials at the municipal level, with hunters, and from the most recent regulatory documents.     

Elasticity Ratio of Resource Consumption and the Resource Consumption

Today the resources are becoming scarcer, which should not be regarded as unexhausted any more. Correspondingly, the production would be constrained by the scarcity of resources clearly. Then the economic researchers would pay much more attention to reducing the consumption of natural resources in the future. Therefore this paper brings foreword the conception of elasticity ratio of resource consumption based on the concept of elasticity and analyzes the relationship between the parameters. For the certain relationships between the elasticity ratio of resource consumption and resource consumption, this paper will try to reveal, to keep economy growing while resource consumption reducing, what conditions should be met as to the relationships among resource productivity, its growth rate, energy saving efficiency, economic growth rate and elasticity ratio of resource consumption. This paper proves the relationship between the China＇s energy consumption and economy growth using statistic data from 1978 to 2003.     

底质营养盐对菹草生长及养分分配的影响

在野外池塘中,利用3种不同营养状况的底质研究底质营养盐对菹草生长及养分分配的影响,结果表明：沉水植物菹草面对底质营养盐的胁迫出现了急性的生理生化反应,在生长初期叶片总的可溶性糖含量在肥沃的底质上高于贫营养底质上;根、茎、叶和石芽各构件都具有异速生长现象,并且表现规律不一样;菹草的根冠比随底质营养盐的不同而变化;随着营养条件对菹草生长胁迫加重,根、冠的异速生长愈明显,同时石芽的N∶P和C∶N比率显著受底质营养盐的影响,而菹草叶片和茎N∶P和C∶N比率不受底质肥力的影响,这些响应将改变石芽第2年的命运和影响种群的维持;在胁迫生境下,菹草首先分配资源到无性繁殖体--石芽上以便维持种群的延续,以回避策略应对底质营养盐胁迫。     

水资源价值理论研究进展与展望

水资源价值理论是价值核算的基础,在水资源价值研究中举足轻重。水资源价值研究是在对传统自然资源价值观反思的基础上开展起来的,伴随着现代经济的迅速发展,人们已认识到传统的价值观念难以适应现代化经济发展的需要,水资源价值理念必须进行重新认识并加以完善。旨在分析水资源价值理论的研究进展,提出未来发展的方向,给水资源价值理论研究以启示。首先分析了水资源价值的构成和内涵,指出水资源价值是经济、社会、生态环境价值的统一;接着详细介绍了各价值论的主要观点,并分析提出了目前存在的主要问题;最后在展望部分从生态经济学角度出发,将能值价值论引入水资源价值研究中,提出水资源能值价值理论的想法,以期为水资源价值评估提供有启发意义的思路与方法。     

The environmental impacts of regional disparity in population and wealth distribution in Nigeria

The disparity in both population and wealth distribution in Nigeria by geo-political zones is well recognized. There is also the recognition that some of the environmental problems in certain sections of the country can be attributed to the imbalance in both population and wealth distribution. Hence the various agitations for environmental resource control in the country. What is lacking however is the research that shows the magnitude of the linkages between the disparity and the environmental degradation in regional context. This provides the basis for this research. To achieve the aim of the research, a STIRPAT model was employed as an analytical tool. The findings show that the southern geopolitical zones are generally more densely populated and wealthier than the northern zones. The south is also experiencing a higher degree of environmental resource degradation attributable to anthropogenic factors. Thus, there is congruence between population density, wealth distribution and environmental degradation in Nigeria. Therefore the achievement of sustainable environment and development in Nigeria requires deliberate policies to mitigate the impact of population concentration and wealth creation on the environment.
