Design principles for origin-destination flow maps

Origin-destination flow maps are often difficult to read due to overlapping flows. Cartographers have developed design principles in manual cartography for origin-destination flow maps to reduce overlaps and increase readability. These design principles are identified and documented using a quantitative content analysis of 97 geographic origin-destination flow maps without branching or merging flows. The effectiveness of selected design principles is verified in a user study with 215 participants. Findings show that (a) curved flows are more effective than straight flows, (b) arrows indicate direction more effectively than tapered line widths, and (c) flows between nodes are more effective than flows between areas. These findings, combined with results from user studies in graph drawing, conclude that effective and efficient origin-destination flow maps should be designed according to the following design principles: overlaps between flows are minimized; symmetric flows are preferred to asymmetric flows; longer flows are curved more than shorter or peripheral flows; acute angles between crossing flows are avoided; sharp bends in flow lines are avoided; flows do not pass under unconnected nodes; flows are radially distributed around nodes; flow direction is indicated with arrowheads; and flow width is scaled with represented quantity.     

Unraveling Hong Kong Geopark experience with visitor-employed photography method

Geoparks have been established around the world with the major objective of protecting significant geoheritage features and reinforcing geoconservation ideas and support through educating visitors. Understanding visitors' perception of geoheritage can inform educational and conservation endeavors. This study used the visitor-employed photography (VEP) method to unravel visitor perception of geoheritage and associated natural and cultural features in the recently designated Hong Kong Global Geopark of China (HKGP). Participants were asked to take photographs of scenes with an effect on their experience in the HKGP and to elaborate in a logbook the chosen subject, reason of choice, and effect on their travel experience. Aimed at capturing real-time and organic experiences, it was found that geoheritage plays a major role in HKGP visits. Visitors develop strong emotional connections with nature through appreciating and learning about prominent features of both small and landscape scales. However, a mismatch was found between visitor belief or incorrect geological or geomorphological knowledge with inherently strong enthusiasm in deciphering the science behind geoheritage. The findings permit development of a new approach of geopark interpretation, commencing with aesthetic and emotional connections with geoheritage features. Modification of fixed on-site provisions and guiding services directed at visitor interests can better spread geoheritage knowledge and reinforce geoconservation ideas. Modeling after overseas practices, a park ranger system, audio guide devices and smart phone applications are essential to achieve meritorious geopark management, appreciation, and enjoyment.     

Aesthetic evaluation of yardang landforms landscape: the Dunhuang Yardang National Geo-park example

Dunhuang Yardang National Geo-park,situated in the Gansu Province of northwestern China(40o25'36 "N–40o33'10" N,93o00'00 "E–93o13'30" E),was chosen as a research locality of aesthetics evaluation of yardang landforms landscape.The yardang landforms landscape is a composite structural system of patch-corridor-matrix,with four landscape unit elements as dense group,sparse group,single body and remnant.The study of the landscape aesthetics spatial pattern of Dunhuang Yardang National Geo-park shows that yardang dense group,sparse group and single body provide the greatest contribution to the aesthetic value of yardang landforms landscape.Yardang bodies are scarce,unique,irreplaceable,and priceless resources in yardang landforms areas.However,they are easily destroyed under the influence of the natural and artificial factors.Therefore,when the tourism potential of yardang landforms landscape is exploited,the protection should be fully improved.     

南昌市厚田乡风沙地貌形态特征与美学价值

南昌市南部新建县广泛分布由古风沙和现代流沙组成的沙化土地。在野外地质调查的基础上,选择新建县南部厚田沙地作为研究对象,应用观察法、描述法和系统调查分析法等定性评价方法对上伏风沙地貌的类型和特征进行分析,并结合下覆古风沙的OSL年代、粒度组成及色度参数等定量分析方法,探讨亚热带湿润区风沙地貌遗产的美学特征。结果表明:厚田风沙地貌包括现代风沙沉积和晚第四纪古风沙沉积。现代风沙沉积大致始于14 ka B.P.,以纵向沙垄、穹形沙堆、辫状沙堆、平沙地等微地貌形态为主;晚第四纪古风沙沉积时间约为77.0~14.9 ka B.P.,以板状交错层理为主,地层序列丰富,是蕴含古环境演变信息的特殊地质遗迹,具有重要的科学研究价值。风沙地貌具有色彩美、旷远美、形式美和生命美等美学特征,具有良好的地学旅游开发价值。定性评价与定量分析相结合,可丰富风沙地貌美学研究的内容,也可为中国南方亚热带湿润区风沙地貌的地质遗迹保护和地学旅游开发提供参考。

论影视艺术欣赏的审美关系

影视艺术欣赏是人类在精神上对美的需求且与其对应的、按美的法则建造的“第二自然”,具有审美属性;是一种审美创造与审美关系。从悲剧、悲剧感,喜剧和喜剧感及其审美价值等方面均可印证这一说法。

Estimation on Aesthetic Value of Tourist Landscapes in a Natural Heritage Site： Kanas National Nature Reserve, Xinjiang, China

Most world natural heritage sites are designated partly by reason of their prominent aesthetic values in accordance with Article Ⅶ of World Natural Heritage Convention.In this paper, the aesthetic values of Kanas National Nature Reserve, which has potential for such designation, was analyzed quantitatively using scenic beauty estimation(SBE).The landscapes of 19 representative scenic spots in the Kanas National Nature Reserve in summer and autumn were selected as the objects of evaluation.The contributions of different landscape factors to the aesthetic value of the Kanas National Nature Reserve were revealed using a multivariate quantitative model.The main factors affecting the aesthetic value were waterscapes, vegetation, mountains, folk culture and the tourist environment.The t-test and F-test results are extremely significant.According to the results, some suggestions were given for conserving the landscapes in the Kanas National Nature Reserve.
