在内涵解析的基础上,主要从数据质量评估、贡献者分类与动机以及法律议题三方面归纳与梳理国外自发地理信息的研究情况。相比较而言,我国对自发地理信息的研究无论从深度还是广度上都处于起步阶段,未来研究应从四个方面深入开展:政府主导下的公众贡献自发地理信息;数据质量控制;移动自发地理信息以及自发地理信息涉及的法律议题。  相似文献

Use of public participation geographic information systems (PPGIS) studies that collect local knowledge in a spatial format is increasing as a tool in natural resources management. Qualitative PPGIS studies have been conducted as individual interviews, as workshops, and in focus groups. As the number of qualitative PPGIS studies increases, so does the need to understand their quality. Saturation, the point when the researcher determines that the collection of additional data will provide minimal new information as it relates to a particular issue, directly reflects on the validity of the study. While the concept of saturation is well established, it is still inconsistently assessed and reported. Furthermore, how saturation applies to qualitatively collected spatial data has not been addressed. A method is presented to assess spatial saturation of qualitative PPGIS data from 19 focus groups that were conducted to investigate important places for recreation, livelihoods, and the environment in the Florida Panhandle.  相似文献

Stakeholder participation is vital when introducing and implementing ecosystem-based management (EBM) at any scale. This paper presents the results of a survey covering four European Regional Seas (Baltic Sea, Black Sea, Mediterranean Sea and North-East Atlantic Ocean) aimed to collect stakeholders׳ perspectives on their Regional Sea governance to implement the European Union (EU) Marine Strategy Framework Directive (MSFD). In this survey, drivers of good governance including stakeholder involvement, willingness and capacity to cooperate, efficiency, institutional ambiguity and decision-making were explored. The results indicate a clear gap in perception between the current, the ideal and the foreseen situation regarding the implementation of the MSFD. The preferences for the future governance structures vary between stakeholders and across seas although some similarities can be found. Based on the results of the survey, this paper concludes that tailor-made rather than off-the-shelf solutions will be needed to accommodate regional cooperation in the European marine environment for implementing ecosystem-based management under the MSFD.  相似文献

针对公众参与的兴趣点数据在有效性的处理或评判中的不足,文章以最为常见的LBS签到数据为研究目标,以兴趣点与地图上普通点要素的区别为出发点,从公众的地理空间认知和兴趣点的空间特性两方面分析影响兴趣点数据有效性的因素,由此建立有效性度量模型,最后对实验区签到数据进行了有效性计算。实验结果表明,该模型可剔除原始数据中的大量无效数据,为以公众参与方式收集的兴趣点数据的有效性提供了切实可行的评判方法。  相似文献

The object of the paper is to provide an insight into the changes in livelihood strategies of the people in the Garhwal Himalayas over time. From sustaining an economy based on transit trade and subsistence agriculture, there has been a shift towards tourism in recent times. This shift has been due to the tradition of pilgrimage to the higher reaches and also due to promotion by the state by developing infrastructure and providing incentives. The paper is divided into four parts. In the first part, the policies of the colonial state and the events leading to the destruction of forests and the impoverishment of the self-sustaining semi-pastoral economy in the Garhwal Himalayas are outlined. It is argued that the destruction of forests and subsequently, the economy of the Himalayas were directly responsible for the large-scale migration to the plains. This also led to further exploitation of forests by the people who were unfamiliar with any other form of livelihood. The paper also discusses the policies of the newly independent Indian state and sees them as an extension of the British policy of large-scale exploitation of Himalayan forests for the purpose of development and economic growth. In the third section, the growth of ecotourism as a direct outcome of the orocess of deforestation and as resulting from the need of society to conserve and yet to earn a livelihood is discussed. The case study of the Gangotrir egion examines the dilemma faced by the people of Garhwal in sustaining their livelihood, income or the development in the area. In addition, tourism has fostered monopolies of groups external to the region thereby contributing neither to the income or the development in the area. In addition, there is an added threat to the environment-deforestation, and erosion-a direct outcome of increased and unplanned tourism. Such problems demand state intervention and management of t.ourism. The conclusion to the paper asserts that in order that the requirements of the society to progress and to sustain itself in its natural habitat are not compromised, it is essential to increase the process of democratization by strengthening local structures and by vesting the community with the autonomy to determine its future. The paper therefore argues that ecotourism in the Himalayas undertaken without local involvement is not desirable. The constant need for local monitoring of external agencies or even of the State‘s participation and the need for re-evaluation of environmental standards are cumbersome details that add to the costs of promoting low-impact tourism. To be viable, ecotourism should be community based and the needs of the community, their ideas of conservation should be given prime importance and local community must be encouraged to review the standards governing conservation. Local structures should thus receive patronage and promotion, so that ecotourism becomes a dynamic facet of economic development.  相似文献
