国家公园领域财政事权划分改革研究

随着自然保护地的整合优化和财政体制改革的深入推进,对国家公园领域财政事权和支出责任进行明确划分、界定,对于建立健全国家公园领域资金保障机制具有重要意义,有助于建立政府间权责明晰、协同有序的国家公园治理体系。本文在梳理我国国家公园领域财政事权清单、分析财政支出责任划分现状及存在问题的基础上,根据中央有关国家公园事权的文件以及部门机构职责、中央和地方财政关系的制度特点,提出我国国家公园领域政府间财政事权和支出责任划分的总体思路与政策建议,为建立以国家公园为主体的自然保护地体系提供决策参考。     

Planning for environmental justice in an urban national park

Urban national parks were designed in the 1970s to bring nature and recreational opportunities to socio-economically disadvantaged communities in the USA. Using the theoretical frame of environmental justice, this paper discusses findings of a recent survey of visitors to Los Angeles' Santa Monica Mountains National Recreation Area – the United States' largest urban national park. Findings show park visitors were predominantly white, affluent, and lived nearby. People of colour travelled further, were significantly less likely to be return visitors, and were less inclined to use the park for active recreation. Seemingly, this park fails to meet the needs of the disadvantaged urban communities for whom it was created, a problem that may also affect other parks in the United States and potentially parks in other countries. Park planners and managers can take practical steps to increase accessibility to this park for people of colour and low-income earners, and should monitor other parks for patterns of ethno-racially differentiated access and utilisation.     

The Relationship Between Environmental Concern and Acceptability of Environmental Impacts among Visitors to Two U.S. National Park Settings

This study examined the relationship between environmental concern and ratings of acceptability of environmental impacts among visitors at two national park settings. Based on the concept of a social ecological paradigm shift, it was hypothesized that individuals with greater levels of environmental concern are less accepting of environmental impacts in national parks than individuals with lesser degrees of concern. Sample data came from Cape Lookout National Seashore (N=392) and Moores Creek National Battlefield (N=236), two national park units in the south-eastern U.S.A. Environmental concern was measured by the New Ecological Paradigm scale. Acceptability was measured by visitor responses to 25 items covering different types of environmental park impacts. Analysis of variance and Tukey's means comparison procedure were used to test for differences between groups defined by levels of environmental concern on impact acceptability. Significant relationships were found between environmental concern and 15 of the 25 specific impacts in the Cape Lookout sample and 13 significant relationships were found in the Moores Creek sample. However, the relationships between environmental concern and acceptability varied somewhat across the two samples. These findings suggested that individuals with greater environmental concern were less accepting (or tolerant) of certain types of park impacts, while individuals with lesser degrees of environmental concern were more accepting of certain park impacts. Differences across the study settings were attributed to the different orientations of park visitors between the two national park units and recency effects. While the data reported are preliminary, they should be informative for park management purposes, particularly in the determination of standards for park impacts.     

Transboundary governance of the Curonian Spit World Heritage Site

This study describes the governance and management structures of the Curonian Spit World Heritage Site, a transboundary protected area shared by Lithuania and the Russian Federation. Focusing on the national park authorities it presents the site from a local administrative perspective. The paper shows that due to strong state level influence and a lack of full stakeholder inclusion, different philosophies and priorities on both sides of the border challenge common management efforts and co-operation. Presenting the existing problems the paper points out the need for increased efforts at the state level as well as for the full inclusion of local communities to remove obstacles and foster co-operation. Hence, by adapting to certain environmental and transboundary governance principles, conflicts can be avoided and better results achieved.

国家公园分区管控的实践总结与制度进阶

分区管控是实现国家公园严格保护与合理利用双重目的的基础制度,也是保障原住居民发展权益的有效途径。梳理总结各试点公园的分区管控制度,本文发现存在实体规范各行其是、程序规范先天不足、责任规范流于形式的问题,难以实现保护优先、兼顾利用之间的关系。国家公园法应统一分区标准,采取二阶结构的分区管控制度,首先以世界自然保护联盟提出的\"三圈层\"模式划分严格保护区、缓冲区、一般控制区,进而将一般控制区划分为游憩展示区和传统利用区,并将生态保育修复区作为特别的\"动态分区\"。同时,提高国家公园规划及变更的审批权限并完善分区管控的法律责任,以实现实质的差别化管控和严格规范的管理。

A market for nature: linking the production and consumption of organics in Tuscany

Contemporary analysis of the food sector has failed convincingly to link production to consumption, and it has not provided a sociological account of such links. This paper makes a provisional attempt to begin such an analysis and does so by examining the case of the market for organic food in Tuscany. It proposes that the ‘pioneers’ of organics in this region constituted a new food movement that succeeded in opening up a new market. However, this market could only be successfully expanded once other actors were enrolled in the market-making process, notably state agencies and supermarkets. The regional government, through new regulations and specific initiatives, integrated organic foods into rural development policy, thereby assisting producers in the process of conversion. Supermarkets co-operated in the implementation of these policies and made space for Tuscan organic products in their stores. So while the ‘pioneers’ began the process of market building, these later entrants were crucial to the stabilization and expansion of the organic sector in Tuscany. Thus, it can be concluded that the emergence of these new ‘markets’ for nature can only be adequately explained by analysing the full range of actors. Copyright © 2001 John Wiley & Sons, Ltd.     

淄博市大气颗粒物中POPs污染水平研究

为了调查淄博市POPs的污染水平,在全市不同功能区设置了5个采样点,采集了采暖期和非采暖期大气颗粒物样品。在对颗粒物样品进行前处理后,通过GC/MS和GC-ECD,分析测定了颗粒物上PAHs、PAEs、PCBs和OCPs四类典型POPs的浓度。结果表明,淄博市市区混合区和县城混合区污染较为严重,采暖季污染较非采暖季严重,这归因于采暖季燃煤量的增加。PAHs成分以4~6环为主,PAEs以DBP和DEHP为主,PCBs污染主要以四氯联苯、五氯联苯和六氯联苯为主,OCPs中含量最高的是艾氏剂和狄氏剂。     

Statistical evidence on the effectiveness of sewering to protect groundwater from VOC contamination

Volatile organic compounds (VOCs) are an important source of contamination of groundwater supplies in Massachusetts and many parts of the United States. One local response is to require sewering in wellhead protection areas as an easily enforceable policy designed to reduce the probability of VOC contamination of groundwater. Data were collected for 238 wellhead protection areas in Massachusetts on VOC contamination levels and the sewered and unsewered land uses in those aquifer recharge areas. Logistic regression procedures were used to see whether sewering had any statistical effect on likelihood of contamination of well water. The results provided limited, but not overpowering, support for the idea that requiring commercial and industrial land uses to use sewers would reduce the chance of VOC contamination.
