三生共赢:可持续发展的根本目标与行为准则

明确可持续发展的行为目标。制定相应的评价准则，是可持续发展思想从理念探讨向实践操作延伸的必由之路，也是进行社会行为选择的依据。在系统分析生活、生产与生态之间的关系后，提出应将“生活水平不断提高，生产能力不断增长和生态环境不断改善”(简称“三生共赢”)作为可持续发展的行为目标和评价准则，并从理论上对这一命题进行了阐述。     

生态文明与农业发展

农业作为国民经济的基础,是生态文明的重要内容,其文明程度直接体现生态文明程度.生态文明建设给农业经营提出了更高的要求,也为农业生产的发展指明了方向.充分认识生态文明建设与农业生产的关系,加强农业相关人员的生态文明教育和农业环保法制建设,实施更加科学、文明的农业经营方式将对促进农业的可持续发展和生态文明建设发挥积极的作用.     

Introduction: Natural Capital, Poverty and Development

Can development occur without running down natural resources in an unsustainable way? The concept of natural capital offers a way for those with divergent views (ecologists and economists for example) to discuss this difficult question. Four aspects are examined in detail. First, the role of institutions in facilitating sustainable development is discussed, with examples from forestry. Then examples from (eco)tourism illustrate the potential – and limits – of applicability of the concept. Measurement issues for natural capital are then considered in detail. Finally, the concept is applied to agricultural strategy in fragile lands, where the tradeoff between the environment and development is likely to be most severe. Some implications for future research and policy are developed.     

Production, Consumption and the World Summit on Sustainable Development

At the World Summit on Sustainable Development (WSSD), world leaders agreed that eliminating unsustainable production and consumption is one of the three overriding objectives of sustainable development. Achieving that objective should have been a major priority for the WSSD Plan of Implementation. Increases in consumption and production over the past decade were largely responsible for the worsening environmental and social trends. Unfortunately, the negotiators of the Plan paid insufficient attention to the lessons from 10 years of discussions about the concepts, the available policies and tools and their effectiveness, the impacts of those policies on developing countries, and the political commitment of countries in an era of globalization. Despite a promising proposal for a new ten-year work programme aimed at bridging the gap implementing the Agenda 21 commitments from Rio, Summit negotiators produced barely more than a muted echo of recommendations from the past which have yet to be taken seriously enough by the world's leaders in a comprehensive intergovernmental strategy. In the ten-year review of progress to achieve sustainable production and consumption (SPAC), governments quickly skipped past the critical work of examining why things are getting worse, avoiding the task of identifying the obstacles (which in some cases were themselves) and in turn avoiding the commitment to time-bound measurable targets. If nothing else, the WSSD demonstrated that a global strategy to achieve SPAC will come not from a UN consensus of world leaders but from a strategic alliance of responsible governments, civil society and others with a vision beyond the next election cycle.     

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。

我国东部沿海地区差距状况以及经济低谷地区的崛起

我国是区域发展差异巨大的大国之一，存在着多种尺度的区域发展差异。从中小尺工区域差异的角度，分析了我国东部沿海地区内部发展差距扩大趋势有其影响，可以看出，东部沿海地区在经济快速发展的同时，也存在着经济相对落后的低谷地区。沿海经济低谷地区分布相对集中于香港－－珠江三角洲、上海－长江三角洲、京津唐－环渤海三个经济隆起带之间，处于省际交界处。按照类型可以分为黄泛平原区、丘陵山区和沿海库区。东部经济低谷地区区位条件相对比较落后，交通可达性较差，产业结构单一，城市化水平发展严重滞后，社会经济发展比较缓慢，这些不利因素制约着该地区经济和社会的发展。根据崛起机制和途径，低谷地区发展呵以分为资源转换型、非国有经济推动型和外资推动型。建议国家修筑贯穿沿海经济低谷地区的东部沿海铁路大通道，降低沿海经济低谷地区设定标准，加快农业产业化发展，对特殊贫困地区实行特殊优惠政策，从而促进东部沿海地区经济协调发展。     

中国农业发展过程中的生物多样性影响及一体化途径

改革开放以来，我国农业得到了迅速的发展，但是以稳步提高农产品供给的农业发展模式在迅速促进农业发展的同时却忽视了对农业生态环境的保护，带来了严重的生态环境问题，给生物多样性造成了巨大的负面影响；生物多样性的减少和生态环境的恶化又危及可持续农业发展，因此，农业需要寻求新的发展模式。本文对农业发展对生物多样性的影响进行了理论与实证分析，论证了生物多样性对实现可持续农业发展的支持作用，提出了用生态农业改造传统农业，从而实现农业发展与保护生物多样性的双赢。     

Assessing Tourists' Preferences for Recreational and Environmental Management Programs Central to the Sustainable Development of a Tourism Area in the Dominican Republic

The main goals of this paper are to (1) highlight the need for sustainable development as a means to conserve natural resources and the environment, which often represent the basis for tourism development, (2) illustrate the importance of assessing tourists' preferences when designing programs and policies central to the sustainable development of a tourism area, and (3) study tourists' interests in sustainable development. With these goals in mind, 180 tourists from Europe, Latin America, and North America were interviewed as they were leaving the resort region of Punta Cana in the Dominican Republic. The main factors that they considered when deciding where to go on a beach vacation were evaluated, as well as their preferences regarding four programs designed to improve recreational and environmental management of the area. Preferences by tourists were elicited both in monetary and non-monetary terms. This paper reports the non-monetary analysis of the data. The results indicate that clean ocean water and beaches, quality of services, and price are the most important factors considered by the respondents before deciding to come to Punta Cana. It was not possible to obtain reliable responses on how tourists perceived the four programs contributing to the sustainable development of Punta Cana. Nevertheless, they expressed high interest and willingness to pay for two of these programs: the outdoor aquarium and the Water Management Program. The results reported in this paper show how important it is to elicit tourists' preferences of programs central to the sustainable development of tourism areas since these preferences can drive managers' development decisions in more sustainable directions.     

A comparative analysis of predictors of sense of place dimensions: attachment to, dependence on, and identification with lakeshore properties

Sense of place can be conceived as a multidimensional construct representing beliefs, emotions and behavioural commitments concerning a particular geographic setting. This view, grounded in attitude theory, can better reveal complex relationships between the experience of a place and attributes of that place than approaches that do not differentiate cognitive, affective and conative domains. Shoreline property owners (N=290) in northern Wisconsin were surveyed about their sense of place for their lakeshore properties. A predictive model comprising owners' age, length of ownership, participation in recreational activities, days spent on the property, extent of property development, and perceptions of environmental features, was employed to explain the variation in dimensions of sense of place. In general, the results supported a multidimensional approach to sense of place in a context where there were moderate to high correlations among the three place dimensions. Perceptions of environmental features were the biggest predictors of place dimensions, with owners' perceptions of lake importance varying in explanatory power across place dimensions.
