生态足迹方法在土地利用总体规划实施评价中的应用——以常德市鼎城区为例

生态足迹作为一种可持续发展状况的定量测度．反映了人类对各种自然资源的利用程度。文章以鼎城区1998年和2006年统计年鉴的数据为依据．计算分析了鼎城区规划实施期问1997年和2005年的生态足迹。结果表明1997年人均生态足迹赤字为2．032hm^2；2005年人均生态足迹赤字为2．644hm^2。土地利用处于不可持续状态。针对目前的情况提出了新一轮土地利用总体规划编制的建议。     

甘肃省阿克塞哈萨克族自治县夏季鸟类调查

陕北石油产区生态可持续发展研究--以靖边县为例

陕北石油产区气候敏感,自然环境恶劣,是我国生态建设重点区。近年来化石能源的大力开采导致当地本来脆弱生态环境发生了显著的变化。为准确对石油产区近年来生态环境变化情况进行定量研究,文章选取陕北石油产出重地靖边县为例,运用生态足迹模型对其2001~2008年的生态足迹变化进行了计算分析。结果表明,8年内全县生态承载力下降了0.223hm2,生态足迹增加了15.775hm2,生态赤字增加了16.0hm2,生态压力指数增长近6.5倍。对6种生态生产性土地的生态赤字/盈余的计算表明,除了林地和水域有少量生态盈余之外,耕地、草地、化石能源地和建筑用地均存在不同程度的生态赤字。同时得出,石油开采是造成靖边县生态赤字的最主要影响因素,2008年石油开采生态赤字已占当年总生态赤字32.5%。大量的化石能源开发使得靖边县生态已处于严重不可持续发展状态。

旅游资源的捆绑开发--以湘西凤凰县为例

凤凰县旅游资源丰富多样,特色鲜明,且资源配合好并相对集中,具有很大的旅游发展潜力。但与周边地区的旅游资源存在一定的趋同性,因此如何立足资源的优势,进行资源的合理捆绑开发和利用,是凤凰县旅游业健康持续发展的关键。     

An autonomous multi-agent approach to supply chain event management

Organizations have made a significant effort to implement software for planning and scheduling, but disruptive event management is still a problem to be solved. Since a disruptive event can affect the overall performance of the supply chain, SCEM (Supply Chain Event Management) systems presenting different automation levels such as monitoring, alarm and decision support have been proposed. However, the management of disruptive events, taking into account the distributed nature of the supply chain, the members' autonomy and the ability to exert corrective control actions, has been identified as a problem that requires further research. This work presents an agent-based approach for the SCEM problem, which can perform autonomous corrective control actions to minimize the effect of deviations in the plan that is currently being executed. These control actions consist of a distribution of the variation between supply chain members, using the plan's slack in a collaborative way. An innovative feature of this approach is its focus on resources, which are affected by disruptive events in a direct way. Based on this approach, a SCEM system is designed as a net of control points defined on resources connected through supply process orders. Two novel aspects are the distributed collaborative inter-organizational architecture of the SCEM system and a Double Contract Net Protocol. This protocol allows a set of resource:representing agents to interact through an agent, representing a supply process order as a mediator. An application to a case study of the Multi-Agent SCEM system implemented with JADE is provided.

陕西洋县朱鹮河流栖息地生境修复 研究

河流是朱鹮重要栖息地之一,在朱鹮逐渐转移至低 海拔区域生存的趋势下,提高河流栖息地生境质量是当前朱鹮 保护的重要内容之一。利用数据收集、现场调研、ArcGIS等 分析方法对近年来河流栖息地生态变化过程进行分析,分别从 栖息地适宜性、景观格局指数及生境质量3个方面探讨朱鹮河 流栖息地质量的状况,从中找出朱鹮河流栖息地生境的具体问 题。从不同河流生境尺度,探讨朱鹮河流栖息地的修复方法。     

Personalist Economics: Unorthodox and Counter-Cultural

There are two reasons why personalist economics lies outside the mainstream. Personalist economics (1) rejects the premises of mainstream economics, and (2) takes exception to certain dominant values of today's culture whereas the mainstream is much more at ease with contemporary Western culture. This paper addresses both reasons and is organized accordingly. In it the author argues that the individualism and the autonomous individual of mainstream economics have their roots in the seventeenth-eighteenth century Enlightenment, that is well before the development of electronic means of communication. Personalism and the acting person of personalist economics emerged during the electronic stage of communication and, the author argues, are much better suited to the twenty-first century. The author calls for a reconstruction of economics which would replace the autonomous individual with the acting person.     

旅游强县向旅游城市跨越的战略构想——以星子县为例

基于星子县旅游业发展的现状,九江市政府提出要使"星子旅游业由景区建设向旅游城市跨越".这是旅游自身发展规律的内在要求,是地方经济社会发展的现实需要.星子县自然山水与文化元素变相辉映,大规模高品味旅游资源集聚,旅游市场基础好,又处于庐山、鄱阳湖两大旅游区的中心,区位优势十分明显,在江西省努力构建环鄱阳湖生态经济区的政策背景下,星子县具备由旅游强县向旅游城市跨越的可能性.在此基础上,我们针对星子县的实际,提出了实现这一跨越构想的战略对策.
