区域视觉形象识别系统设计的理论与实践

目前，全国各地正在兴起区域形象设计与建设的浪潮，但如何把区域形象信息系统地传递出去，这方面的理论研究大大落后于实践。文章就区域形象信息传递的有效工具－区域视觉识别系统设计的主要内容，设计的原则，设计的基本流程等在理论与实践上作了较为详细的探讨，并就区域视觉识别系统设计方案的经济学论证作了一些有益探讨。     

旅游信息系统建设模式探讨——以佛山市为例

作为当前旅游信息系统开发的两种主要基础平台，地理信息系统和多媒体制作系统都存在一定的缺陷。多媒体制作系统缺乏旅游地图的有效管理，空间查询，分析和统计功能，旅游地理信息系统则缺乏旅游信息的多媒体表达能力。从实用性和普及性出发，集合二者优点开发模式具有更大的推广应用价值。因此，论文提出在同一界面下基于GIS和多媒体集成的旅游信息系统开发模式；（1）在GIS中增加多媒体信息表达能力，以关系数据库为核心，把多媒体文件名信息存储在地理信息系统属性库，依靠多媒休段实现多媒体数据与地理信息系统图形和属性的关联，实现查询的基本概念；（2）在多媒体系统中开发部分GIS空间查询功能。以此思路，佛山科技学院GIS技术实验室利用VB进行GIS和多媒体二次开发，成功地完成了佛山旅游信息系统的设计和开发。     

旅游自组织系统:区域旅游规划的根本目标

随着旅游活动不断走向大众化，旅游现象各要素之间已形成相互联系，具有特定结构和功能的有机整体，即旅游系统，旅游规划的对象也由旅游业发展到旅游系统。文中认为旅游系统规划的最终目标就是促使旅游系统6向旅游自组织系统进化，为促进旅游自组织系统的形成，编制科学的规划方案是基础，加强规划的实施监控是关键，成立实施监管小组是制度保障。

基于GIS的滑坡CF多元回归模型及其应用

目前基于GIS滑坡变形失稳危险性评价方法均有各自的局限性。本文在基于数据的数学统计模型的基础上提出CF多元回归模型。通过将滑坡确定性稳定系数与回归模型的融合，在一定程度以解决了滑坡评价过程中影响因子的选择和量化的问题，有利于建立准确的滑坡分析模型。最后，将模型应用于云南小江流域，进行了该区的滑坡空间分布及稳定性分析。     

The application of GPR to barrier-lagoon sedimentation study in Boao of Hainan Island

Sedimentary successions and internal structure of the coastal barrier-lagoon system of Boao, eastern Hainan Island were studied through utilizing data from test holes and trenches and ground-penetrating-radar (GPR) profiles. During late Pleistocene, fluvial and delta plains developed over an unevenly eroded bedrock during low sea level stand, followed by the formation of littoral and lagoon facies and defined coastal barrier-lagoon-estuary system during the post-glacial uppermost Pleistocene-lower Holocene eustatic rise of the sea level, and the upper Holocene high stand. GPR results show that Yudaitan, a sandy coastal bar backed by a low-laying land (shoal) just east of the active lagoon, is a continuous, parallel and slightly-wavy reflectors indicating homogeneous sandy or sandy gravel sediments, and inclined reflectors partly caused by progradation and accumulation of beach sand and gravel. Quasi-continuous, hummocky and chaotic reflectors from the shoal of Nangang village correspond to mixed accumula     

Pauperizing the pastoral periphery: the marginalization of herding communities in the world's dry lands

Environmental degradation and other socio-economic problems are too often discerned in contemporary pastoral systems in the wake of global economic change. This paper identifies cases where pastoral people respond to external pressures and opportunities in positive ways and adapt to changes. We hope that by doing this a framework of pastoral adaptations can be developed. The first part of this paper focuses on impacts of global economic change, which are mostly negative in nature. Through an extensive literature search in geography, anthropology, range management, and development field, the second part introduces cases that we categorize as positive adaptations.

Quasi-continuous, hummocky and chaotic reflectors from the shoal of Nangang village correspond to mixed accumulation of sands and clay. This research indicates the GPR is a non-intrusive, rapid, and economical method for high-resolution profiling of subsurface sediments in sandy gravelly coast.
