区域持续发展与地理信息系统的协调作用

环境与发展是当今人类社会所面临的两大主题,已引起各国政府和国际社会的广泛关注。持续发展代表了一种新的发展战略和我们从事经济活动的新方法。地理信息系统技术具有综合各种社会、经济和环境因素的能力,为科学决策和实现区域持续发展提供了一种强有力的工具。同时,地理信息系统为在区域持续发展中利用生态学方法、时序分析和科学决策提供了强有力的技术支持。在我国,区域持续发展已引起了越来越多的研究机构与政府部门的重视。应该注意到,实现这一目标离不开地理信息系统技术的支持。本文主要讨论地理信息系统对区域持续发展的作用和探讨建立区域持续发展的地理信息系统的理论模式。     

Seeing the wood for the trees: the role of woody resources for the construction of gender specific household cultural artefacts in non-traditional communities in the Eastern Cape, South Africa

There is a growing wealth of data capturing the direct-use values of the environment and recognition of forests and wild resources as representing “the poor manȁ9s overcoat”. This focus has however resulted in an emphasis on the utilitarian values of wild resources for rural livelihoods and has for the most part overlooked their cultural values. In tangent to these developments within the field of anthropology there has been increased attention directed towards the relationship between biodiversity and human diversity over the past decade. This has resulted in the recognition of what the Declaration of Belem calls an ȁ8inextricable linkȁ9 between biological and cultural diversity. The term bio-cultural diversity has been introduced as a concept denoting this link. Consequently there is a need for more elaborate assessments of the various ways in which different groups of people find value in biodiversity. The aim of this paper is to demonstrate the cultural significance of wild harvested plant resources for the maintenance of two gender specific cultural artefacts for amaXhosa people in South Africa, to assess the persistence of these practices in rapidly modernizing communities. We demonstrate the endurance of these ancient cultural artefacts in present-day peri-urban communities and suggest that they point to the need for improved understanding of the significance of bio-cultural diversity. The findings of the study should not be interpreted as illustrating stagnation in the traditional past, but rather as pointing at the need for improved understanding of the significance of bio-cultural diversity in a dynamic sense.

CITIZEN INFLUENCE IN WATER POLICY DECISIONS: CONTEXT, CONSTRAINTS, AND ALTERNATIVES

ABSTRACT: The desirable proportion of citizen input into policy making and the proper mechanism for that input engender substantial conflict in the water resources arena. Nevertheless, discussions of citizen participation in water policy formation generally occur within narrow perspectives both with regard to the issues involved and the alternative mechanisms by which that participation can be realized. This paper examines the historical and current contexts of the controversies and presents a discussion of the alternative processes for citizen influence - called linkage. The linkage processes discussed include direct participation, citizen advisory committees, the pressure group model, the electoral model and the bureaucratic model. Each linkage process is discussed in terms of who is considered the public, how the public influence works, the limitations of the process, and what available water policy-related data suggest regarding the adequacy of the process.     

资源核算及其纳入国民经济核算体系初步研究

实施资源核算并将其纳入国民经济核算体系是保障和促进国民经济持续、稳定、协调发展的重要措施之一。本文论述了对这一问题初步研究的基本思路、框架、方法,并以1988年我国森林资源状况为研究范例,说明了核算方法的具体应用。     

A “RATIONAL” POLICY FOR THE ENERGY AND ENVIRONMENTAL CRISES1

ABSTRACT: The present energy and environmental crises are due to increasing per capita demands as well as increasing populations. The role that traditional pricing policies have played in promoting these demands is discussed. The reduction or stabilizing of per capita demands is advocated through the use of Conservational Pricing mechanisms which charge higher average prices for high consumption. An example of the effect of Conservational Pricing in the water supply industry is given.     

Potentially recoverable resources: How recoverable?

There are a number of factors which are likely to limit the proportion of potentially recoverable resources that will actually be recovered. The most important of these concern the way minerals are distributed within the crust and trends in energy costs associated with mineral production. This article offers a pessimistic view of the prospects for mineral supplies early in the 21st century. The resource situation is even less hopeful when the possibility of extending the material living standards of the developed countries to everyone likely to be living on earth late next century is considered.

长江上游攀西—六盘水地区资源开发与环境保护

长江上游攀西——六盘水地区是个资源富集的“金三角”。通过交通先行,加快资源开发,对增强21世纪经济发展后劲意义重大。但生态环境恶化,急需加强保护。     

从河流网系整体出发开发整治长江流域

长江是我国最大的河流,干流长6300km,流域面积180万 km~2,占全国国土面积的1/5。整个流域大部分位于湿润亚热带地区,具有丰富的自然资源,工农业产值占全国的45%,是我国最发达的地区。但流域内地区发展很不平衡,下游地区的发展超过中游和上游,干流沿岸城市的发展超过丘陵山区。因此,从河流网系整体出发,均衡开发长江流域很有必要。
