Assessment of the natural-cultural resources in Çanakkale for nature-based tourism

While the world is going into different tourism expectations, the tourism understanding in Turkey is defined as tourism in the sea-sand-sun triangle. However, it is possible to contribute to the income and local development of the indigenous people by developing nature-based tourism. Besides, with the sustainable use and preservation of the natural-cultural assets, the damage of the traditional tourism industry on the natural and cultural environment could be reduced. In this study, it is aimed to bring up the nature-based tourism concept in Çanakkale by evaluating the nature-based tourism industry in the general of Turkey and assessing the natural-cultural resources that Çanakkale comprehends. The most important areas that have a nature-based tourism potential in Çanakkale and the tourism activities that are most suitable for these areas have been determined.     

Exploration of Science Parks

1 DEVELOPMENT OF SCIENCE PARKSThe concept of science park originated in the US. Manyterms are used to describe science parks, such as researchpark, technology park, science centre, research centre,innovation centre, and with various combination of these(MacDonald, 1987). The first science park in the worldis Stanford Industrial Park established in 1951. In 1955,only seven companies were located in the park. By 1980there were ninety companies including Hewlett PackardCompany, whic…     

北京市公园土壤铜、铅含量及化学形态分布特征

对北京市的12个公园进行表层、深层土壤样品的重金属Cu、Pb含量分析,并对其中10个公园的表层、深层土壤样品进行Cu、Pb的化学形态分析。研究结果表明:北京市部分公园的深层土壤已在某种程度上受到人为扰动,大多数公园表层土壤中存在着一定的Cu、Pb含量积累现象,总体上市区公园比郊区公园明显。公园表层、深层土壤中Cu形态分布的总体规律均为残渣晶格态>有机结合态>铁锰氧化物结合态>碳酸盐结合态>可交换态,表层、深层土壤中Pb形态分布的总体规律均为残渣晶格态>铁锰氧化物结合态>有机结合态>碳酸盐结合态>可交换态,但表层土壤中活性态Cu、Pb的平均比例较深层土壤均有所上升,部分市区公园表层土壤中Cu、Pb的含量较高且活性态比例较大,具有一定的释放潜力和生物有效性。     

State Park Directors' Perceptions of Mountain Biking

/ This study intended to explore the perceptions of mountain bikingmanagement through a mail survey of state park directors in all 50 states.With a 100% response rate, it was found that 47 states permit mountainbiking in their state parks, however, few state parks have formalized plansto manage this outdoor activity. The management policies that do exist arenot followed on a statewide basis but vary within each state and at eachstate park. Many states have worked cooperatively with local mountain bikingclubs to develop and maintain mountain bike trails, promote rider education,and provide volunteer patrols on trails. The issue of user conflict surfacedwith almost three-fourths of the managers responding that conflict existedbetween mountain bikers and other trail users. This preliminary study shouldprompt further research with on-site managers focusing on the use ofmanagement plans for mountain biking, cooperation between managers and usergroups, and user conflict. It is recommended that an Internet-basedinformation clearinghouse or discussion group be made available to landmanagers by a national bicycling organization.KEY WORDS: Mountain biking; State parks; State park directors;Recreation resource management

Hierarchical pre-positioning of emergency resources for a chemical industrial parks concentrated area

Accidents in chemical industrial parks always cause fateful damage which can be reduced greatly by providing emergency resources sufficiently and timely. One effective way to enhance the emergency response capacity and agility is by pre-positioning of emergency resources for the potential accidents. The Yangtze River Delta of China is a large region where a large number of chemical industrial parks are concentrated. According to the distributing characteristics of demand points in this region, a mathematical model of hierarchical pre-positioning of emergency resources is proposed to ensure that accidents in all chemical industrial parks in this region can be responded timely and effectively. Considering accident domino effect and minimizing the total cost, the model gives optimal decisions of pre-positioning emergency resources, including the location and inventory of depots. The innovative hierarchical pre-positioning method greatly reduces the total cost in the premise of sufficient preparation for supplying emergency resources. Finally, in a visual graph of the Yangtze River Delta, the model is applied and the result shows its applicability.     

化工园区接警处警与应急值守系统的研究

本文分析了目前常用的接警处警系统,针对化工园区安全管理的工作需要,研究化工园区综合接警中心接警处警工作的特点和要求,分析化工园区接警中心工作体系和功能要求,设计开发了化工园区接警处警与应急值守系统。文中对系统体系架构、系统建设关键问题和所需的支持系统进行了详细介绍。该系统集成了地理信息系统的功能,提供化工园区事故接警、通知和处置功能,应用重大危险源监管信息系统、应急预案综合管理系统、综合监控系统等业务系统作为数据支持,为化工园区接警中心管理园区突发事件、实现事故快速反应和及时应对提供技术支持。     

生态工业园评价方法研究:以北京市为例

建立科学有效的评价方法将有助于稳步推进我国的生态工业园建设．而园区所处区域的特点对于评价指标的选择和评价体系的建立具有重要影响。本研究在借鉴国内外最新研究成果的基础上．针对北京工业开发区的发展现状和特点．考虑相关性、可操作等原则，初步提出了一套生态工业园评价指标体系框架及其计算评价方法。评价指标共分为6大类准则，共计25个具体指标．划分为“控制性”指标和“指导性”指标。前者包括：信息基建共事类指标、管理与发展类指标、减量消耗类指标、园区环保类指标。后者包括：循环利用类指标和产业共生类指标。该指标体系蕴涵的思想和理论方法已成为推进北京生态工业园建设的重要借鉴，也可作为国家生态工业园评价方法研究的有益补充。     

基于工业生态化建设的工业园区环境管理研究

工业园区是产业集聚的载体,是区域经济发展的引擎。工业园区同时又是污染产生排放集中地,我国工业园区在发展过程中随着经济总量扩大、资源和能源消耗的增加,出现了大量的环境问题,阻碍了园区的可持续发展。工业园区的环境管理可以从园区层面出发解决污染问题,这是个既复杂又重要的工作。本文在分析工业园区发展历程的基础上揭示了目前工业园区存在的环境问题,以及管理方面存在的缺陷和不足,发现总体上园区环境管理水平较差。工业生态化建设为进行合理的园区环境管理提供了一个契机,本文针对我国工业园区的发展现状及发展趋势,提出基于工业生态化建设的工业园区环境管理的对策:1提升生态工业的意识,鼓励公众参与;2确立生态化建设思想,以生态化建设促进环境管理效率的提升;3加强工业生态化建设相关政策法规、规划的完善和实施;4构建工业生态化建设信息服务平台,以生态化建设来实现工业园区科学的环境管理。     

Willingness to pay and demand elasticities for two national parks: empirical evidence from two surveys in Pakistan

Using survey-based data approach for modeling the demand for environmental goods/resources, this study estimates income and price elasticities of demand for improved environmental quality of two National Parks in Northern Pakistan. The study uses data from two studies. The estimates indicate that improved environmental quality effects can be described as a luxury and an ordinary and price elastic service. Confidence intervals show however that the classification as a luxury is not statistically significant. Income elasticities of willingness to pay are estimated for a broad range of environmental services. The study finds that income and willingness to pay vary directly and significantly. The elasticity estimates, in general, are greater than zero, but less than unity. The study concludes that environmental improvements are more beneficial to low-income groups than for high-income groups.
