It appears particularly important to build city image. As manifestation of city characteristics, it reflects spiritual outlook of a city. More importantly, it is the requirement for unremitting self improvement in urbanization development. Public art embodies spirit and life style of a city. As a product of modern urban form, it has close relationship with the shaping of city image. This article researches on relevance between public art construction and city image shaping, according to general situation of public art construction in Nantong city, and discusses the influence of them. The aim of this article is to promote the shaping of city image more effectively.展开更多

Major international sporting events are the key channels for the exchange and dissemination of information among athletes from various countries, media coverages, national and international audiences which involves interpersonal communication, organizational communication, and mass communication at all levels. At the same time, the volunteers, especially young volunteers (mostly college student volunteers) considered as the Beijing city spokesperson and also as a group of "public diplomacy ambassadors", transfer positive energy in international communication during major international sporting events. Therefore, major international sporting events held in Beijing play an irreplaceable role in the image building of the capital city of China, Beijing.展开更多

At the same time, the map unification and harmonization should be taken into account dur-ing the design process, since some visual conflicts appear when map symbols overlaid on the true color image. The objective of this research is to explore the rules in the process of true color image city map design based on chromatic and aesthetic knowledge. At the end, taking the Image Atlas of Guangzhou as an example, image color adjustment, road network presentation, and symbol de-signing issues will be discussed in the application.展开更多

The aim of this study was to provide a reasonable scientific basis for the more reasonable use of regional land resources of Bole City by study of land use change and driving force of Bole City.[Methods] Through geometric correction, image mosaic and image registration processing and classification of the remote sensing images of Bole City in 2006, 2011 and 2016, the three images of land use change in land use types (land use change range, dynamic degree and variation degree) were studied, and the natural and social economy in terms of the driving forces of land use change were analyzed.[Results] In the 2006 to 2016 period, cultivated land of Bole City had the land use dynamic growth state, and the average growth rate was 0.26%; and forest land, construction land, water, grassland and unused land showed a decreasing trend, decreased by 0.23%, 0.22%, 0.75%, 3.85% and 1.52%, respectively. In the entire study period, the change of grassland was the biggest, the changes of unused land and water were the second, and the changes of cultivated land, construction land and forest land were lesser.[Conclusions] The main driving factors that effected on land use change of the study area were climate, industrialization, urbanization, social and economic activities, adjustment of agricultural structure and population expansion.展开更多

Taking Huadu District in Guangzhou City for example, urban green landscape pattern was analyzed from the level of region and district, according to the landscape ecology. The results showed that local green landscapes had many problems such as unreasonable structure, high fragmentation, unbalanced distribution of green space types, poor corridor networks etc.. In view of these problems, countermeasures for improving green landscape images in Huadu District were proposed.展开更多

It shares borders with China on the north and Thailand on the east. Kengtung is a place which forms a significant historical site in the easternmost part of Myanmar. From the geopolitical point of view, the region was located in a most strategic place. Its situation forced to safeguard the region. The town lies on a critical point of Myanmar’s defences. The restriction of exacting money as a yearly tribute did not concern for Kengtung. The tradition of paying homage was appeased to the King. The ruling Sawbwa which achieved the valuable return presents of the Burmese King. Kengtung came in the first class, and was the most important of the Myanmar’s possessions east of the Thanlwin River. Its position may be roughly judged by the tribute paid to the King and the contigent it was bound to supply to the royal army. Therefore, Kengtung was very important for the security of Myanmar’s eastern frontier during the Konbaung period. It was like a small Union within an Empire together with multinational races of Myanmar. A good deed of past events blanket over the town till today.展开更多
