甘肃省第三产业对经济增长贡献的实证研究

第三产业的加快发展是生产力提高和社会进步的必然结果。大力发展第三产业有利于提高工农业生产的社会化和专业化水平,有利于优化生产结构,促进市场充分发育,缓解就业压力,从而促进整个经济持续、快速和健康发展。利用1991-2009年数据,以向量自回归模型为基础,采用单位根检验、协整分析和格兰杰因果检验等方法对甘肃省第三产业与经济增长之间的关系进行了实证研究。结果表明,1991-2009年甘肃省第三产业总值对GDP的长期弹性为0．35035,第三产业对经济增长具有积极的促进作用。     

基于轴-辐理论的皖江城市带物流网络空间构建

大力发展现代物流业和皖江城市带承接产业转移示范区建设是两大重要国家级战略。首先对轴-辐理论的国内外研究现状进行了总结和归纳,分析了轴-辐网络的结构及其优劣势。其次,设计了物流中心性指数的评价指标体系,运用主成分分析法对皖江城市带的9个地级城市进行物流节点等级划分,根据分析结果的总得分和区位特征确定合肥、芜湖、安庆3个一级物流节点,形成轴三角。分析了各级物流节点间的干线及支线物流通道,构建了皖江城市带轴-辐物流网络空间。     

黑龙江省东部煤电化基地经济与生态环境协调发展评价研究

构建东部煤电化基地是继哈大齐工业走廊启动建设后,黑龙江省做出的一项重大战略部署。基地建设要求深入贯彻科学发展观,大力发展煤化工产业,实现全面、协调、可持续发展。全面协调发展不仅是经济的发展,同时也要考虑生态环境的保护。运用层次分析法和协调发展度模型,研究黑龙江东部煤电化基地经济和生态环境的协调发展程度表明,黑龙江东部煤电化基地经济和生态环境协调发展水平处于中等协调状况。针对评价结果,提出了相应的对策和建议。     

阿坝州大骨节病和扶贫开发决策中AHP方法的应用

大骨节病防治和扶贫开发试点工作涉及阿坝州的经济、社会、生态等各方面,且州内各县、乡、村情况各异,众多具体措施关系复杂。为了提高决策质量,使试点工作取得“优化举措、重点突破”的效果,应用AHP方法建立了定量模型。

旅游产业园：理论模式与实践发展

旅游产业集群式发展成为新的发展趋势和现实要求,但目前国内仍存在多种发展模式。笔者认为,旅游产业园应特别突出旅游产业特色,既要考虑传统的观光度假功能,更应考虑上下游的旅游装备研发制造、旅游商品研发生产、旅游产品营销推广等各个环节。以鄱阳湖生态旅游产业园为例,分析了该产业发展模式的建设背景、战略意义、发展定位和建设内容。     

Learning About the History of Landscape Use for the Future: Consequences for Ecological and Social Systems in Swedish Bergslagen

Barriers and bridges to implement policies about sustainable development and sustainability commonly depend on the past development of social–ecological systems. Production of metals required integration of use of ore, streams for energy, and wood for bioenergy and construction, as well as of multiple societal actors. Focusing on the Swedish Bergslagen region as a case study we (1) describe the phases of natural resource use triggered by metallurgy, (2) the location and spatial extent of 22 definitions of Bergslagen divided into four zones as a proxy of cumulative pressure on landscapes, and (3) analyze the consequences for natural capital and society. We found clear gradients in industrial activity, stream alteration, and amount of natural forest from the core to the periphery of Bergslagen. Additionally, the legacy of top-down governance is linked to today’s poorly diversified business sector and thus municipal vulnerability. Comparing the Bergslagen case study with other similar regions in Russia and Germany, we discuss the usefulness of multiple case studies.     

Network design for water quality monitoring of surface freshwaters: a review

To date, many water quality monitoring networks for surface freshwaters have been rather haphazardly designed without a consistent or logical design strategy. Moreover, design practices in recent years indicate a need for cost-effective and logistically adaptable network design approaches. There are many variables that need to be included in a comprehensive yet practical monitoring network: a holistic appraisal of the monitoring objectives, representative sampling locations, suitable sampling frequencies, water quality variable selection, and budgetary and logistical constraints are examples. In order to investigate the factors which affect the development of an effective water quality monitoring network design methodology, a review of past and current approaches is presented.     

Importance of public information and perception for managing recreational activities in the Peel-Harvey estuary, Western Australia

Surveys of water recreational activities were conducted in the Peel-Harvey estuary. Channels used by recreationists to gain information about water quality, the perception of water quality and resulting behaviour were investigated. This study showed that personal perception, local knowledge and history, absence of warnings and residency were major factors contributing to risk perception and behaviour in this recreational community. Management strategies should take this information into account to achieve maximal outcomes.
