丝路中道旅游产业带开发是优化新疆旅游景区系统空间结构、解决"旅长游短"问题的关键,文章运用分形理论测度样本景点的随机聚集维数和关联维数,评估核心带动地区喀什旅游圈景区系统结构的紧致度和均衡度水平。分维数据显示:以喀什市为中心的旅游圈方圆240km范围内景点系统呈多嵌套分形结构;方圆170km范围内样本景点呈随机聚集态分布,景点布局基本均衡但聚集分布的密度偏低。该结果表明需要着力优化喀什旅游圈的景点布局:①增加A级景区数量,适度提高喀什市核心旅游圈景点分布密度;②加快开发新的中心性景区,即选点打造喀什地区第一个国家5A级景区,构建双中心结构大旅游圈,从分形结构特征看泽普县金胡杨国家森林公园为比较适宜的区位点。从全产业带上看,对阿克苏和巴州等地区布局若干5A级景区创建点位,形成分布均衡、结构紧致的多层级中心地空间体系结构。 相似文献

旅游景区（点）系统空间结构关联维数分形研究——以南京市景区（点）系统为例 总被引：16，自引：0，他引：16
本文以南京市旅游景区（点）系统为例,采用测算与分析空间关联分形维数的方法对景区（点）系统的空间结构进行了研究。根据旅游景区（点）系统空间结构的无标度特性和遵循的进化过程,认为对其空间结构进行分形研究是可行的。南京市景区（点）系统的空间结构是分形的,具有景点系统空间结构演化自组织优化的趋势,在地理区域分布上表现为景点空间分布较集中的特性。同时认为景区（点）系统空间结构具有自仿射性分形特征,景点系统从中心向外围有递变的趋势,且在不同方向上递变的比率是不同的,在地理区域上表现为景点的空间分布越往外围越集中（或均衡）,且不同方向上的集中性程度是不同的;具体到南京市来说是递减的,向南部递减的较慢,向北部递减的较快。同时系统的空间结构也基本具有分形对称性特征。 相似文献

西部地区旅游资源综合分析与开发对策 总被引：14，自引：1，他引：14
西部地区旅游资源十分丰富 ,具有类型多、质量高的特征 ,同时也存在分布分散、基础设施落后、信息闭塞等问题。本文对西部地区旅游资源 (主要旅游资源类型 )的丰度、分布密度 (面积相对密度和人口相对密度 )、类型和质量进行了较为系统的分析。分析结果表明 ,西部主要旅游资源总量占全国总数的 1 3左右 ,其中列入世界遗产名录的自然和文化遗产多达 8处 ,占全国总数的 34 8%。然而西部主要旅游资源的面积相对密度只有全国平均水平的 4 0 %～ 6 0 % ,其中森林公园数目仅为全国水平的 31 % ;而西部地区较高的人口相对密度则意味着较少的当地旅游客源。针对西部旅游资源开发中存在的问题 ,文章提出了一系列建议措施 :①资源开发遵循从点到线、从线到面的分层次的原则 ,形成旅游网络 ;②加强旅游资源宣传力度 ,改善信息闭塞的现状 ;③加强以交通设施为核心的基础设施建设 ;④大力发展与环境保护相结合的生态旅游。 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
