基于Logistic模型与成本加权距离方法的济南城市公园综合可达性分析

城市公园是城市绿色基础设施的重要组成部分，具有重要的社会、经济和生态文化功能，其空间布局合理与否直接影响到城市公园的可达性与公平性．以济南市为例，采用2009年ALOS遥感影像数据，基于RS和GIS软件平台，解译获取了研究区土地利用现状图、道路交通和城市公园等空间数据，构建了城市公园吸引力综合指数，并基于道路网络，采用成本加权距离分析方法计算研究区城市公园的空间可达性，最后基于logistic模型计算了城市公园的综合可达性，以表征城市公园自身属性特征（吸引力）和交通可达性的综合影响．研究结果表明：1）济南城市公园空间可达性和综合可达性总体水平均较好，20min内可达区域约占研究区的80％，但空间分布不均衡，中心高外围低，南部受地形影响可达性普遍较低；2）吸引力比较强的公园周边可达性水平明显提升，说明城市公园吸引力对可达性的影响较为显著．研究结果丰富了可达性研究的内涵，可为城市规划者和决策者进行城市绿地空间布局和城市绿地景观设计提供一定的科学依据与参考．

世界大型主题乐园的区位指数研究

一般认为,旅游资源是不可移动的。但主题乐园属于人造景区受资本和市场共同驱动下,可以在全球范围内布局配置的。因此,主题乐园业区位分析可以从区域经济条件和区域自然条件两大方面来考察,而经济条件又可以从需求和供给两个方面来衡量。需求指向可以从当地居民的消费能力(购买力)和消费规模(购买总量)来测度;而供给指向则是以经济密度、企业经营环境和城市人口数量(具有一定素质的人力资源)来评价;对于大型主题乐园而言,在众多自然条件中气候是最主要的因素。由此,我们分别构建了大型主题乐园的经济区位指数和自然区位指数,并通过加权后得出区位吸引指数。从区位吸引指数的数值和结构可以评价各国大型主题乐园布局的区位优势和劣势,发展潜力和潜在威胁,并结合世界各大区大型主题乐园的发展现状和经营业绩进行实证分析,从而寻找出大型主题乐园区位布局的一般规律。

Application of Disaggregated Logit Modeling with Stated Preference Method in Park and Ride Behavior for Non-local Private Car Travelers in Big Events

During big events, non-local private car travelers can be divided into two types which were returning in one day and in several days. It was demonstrated that those two kinds of travelers have distinct behavior on park and ride （P＆R）, due to their different travel demand and behavior attributes. In this paper focusing on the travelers returning in several days, the travel attributes and requirements for P＆R were analyzed with stated preference survey. A P＆R choice behavior disaggregated logit model was established and calibrated based on random utility theory. The model concludes three variables, which were travel time, parking fee and comprehensive attractiveness index for suburban satellite towns comparing to urban district. The results revealed that for travelers returning in several days the primary key point is increasing the attractiveness of suburban satellite towns.
