Characteristics and Driving Forces of Spatial Expansion of Oasis Cities and Towns in Hexi Corridor, Gansu Province, China

This paper presents an integrated study of urban spatial expansion in the Hexi Corridor, Gansu Province, China based on TM, ETM remote sensing data in 1987, 1990, 1995, 2000, 2006 and 2011. The study explores the characteristics of urban spatial expansion and dynamic mechanism by using expansion speed index, expansion intensity index, compact index, fractal dimension, and extended flexibility index. We built the index system of influencing factors of urban spatial expansion by using the grey incidence model. The results showed that urban spatial expansion rate in the Hexi Corridor has been on the upward trend since 1987. Expansion intensity showed an obvious upward trend, however, the upward trend varied in different urban areas. In addition, the urban structure was loose relatively, but the urban compactness was more obvious. The urban spatial form tended to be simple, and the urban land use tended to become more intensive. Urban spatial expansion experienced several stages: padding internally, external expansion and padding internally. The main driving factors of urban spatial expansion are not the urban water resources and the oasis scale, but one or several factors such as economy, traffic, population, resource and national policy.

Preliminary Analysis on Environmental Impact of Relocation of Cities and Towns in the Three Gorges Reservoir Region

At the normal pool level of 175 m, the inundated areas of the Three Gorges Reservoir involve 2 cities, 11 county seats and 140 towns. The population of the cities and towns under the inundated line totals 393 000 people(1985). These affected cities and towns will be rebuilt by means of moving backward to a higher elevation or to other places.The cities and towns to be relocated are the regional political, economic and cultural centres, and serve as traffic complexes and places of goods gathering and distributing. They are also the seats containing some important cultural relics and historic sites, landscaping and scenic spots. The relocation of the cities and towns will generate far-reaching impacts on regional socio-economy and environment. The unreasonable excavation and fill or the improper protective measures adopted may induce land slide,collapse and soil loss. The ruins and wastes will affect the water quality in the early period of impoundment of the Three Gorges Reservoir. A large demand of timber may result in forest fall excessively in the local area of the reservoir region, and lower forest and vegetation coverage rate may lead to soil loss. The relocation of the cities and towns will increase urbanization in reservoir, improve the infrastructure, enhance their location function and economic radiation capacity. The negative impact will reach its maximum during relocation peak period, and the environmental quality will be progressively improved with the recovery of the functions of the relocated cities and towns and the implementation of environmental protection measures. Finally, the negative impact will be offset, and the negative impact will be changed into positive environmental elements.

International Arts Festivals Visitors＇ Motives and Profile Characteristics： The Case of Two Medium-Sized Greek Cities

This paper presents an analysis of two renowned international arts festivals visitors＇ motives and profilecharacteristics, in two medium-sized Greek cities： the Kalamata International Dance Festival （KIDF） and theDrama International Short Film Festival （DISFF）. The purpose of the study was to determine the reasons visitorsattend these festivals, which is necessary for building more concise marketing strategies and, therefore,more successful and sustainable events, with long-term benefits, ranging from the local to the national levels.The research addresses international arts festivals that share four main characteristics： （1） they host internationalprofessional artists; （2） they feature explicitly-stated artistic visions and objectives; （3） they are publicly funded;and （4） they have achieved a consecutive 23 years of successful presence in each city. These two case studiesrepresent two cultural events which have managed to maintain their popularity and high status, on the Europeanfestival map, as well as to raise their host cities＇ cultural and tourism standards, despite the serious economiccutback they have both faced. Due to limited available funds, the festivals lack marketing resources andspecifically data collection on visitor motivation, a gap which this study aims to remedy. Primary datawere collected with the aid of online structured questionnaires, distributed and collected during autumn2016. Altogether, 130 questionnaires were answered by visitors of the DISFF and 186 questionnaires wereanswered by visitors of the KIDF. Even though both festivals share similar characteristics regarding theirorganization and their aims, our analysis emphasized the heterogeneity of the motives of attendance in connectionwith the visitors＇ profile characteristics, for each event. While some similarities were found, especially betweendemographic sample characteristics and visitors＇ profiles, the general picture to emerge from the findingsindicates significant differences between the two cases. Arts festivals-goers do not appear to constitute a singlehomogeneous market; rather, each event appears to attract different audiences for different reasons. Theimplications of these findings, deriving from statistical analysis, are discussed and suggestions for further researchare outlined. This research aims to contribute to knowledge concerning the marketing strategies of internationalarts festivals in medium-sized cities, useful for research and academic purposes, as well as to local and nationalauthorities and other agencies and bodies, responsible for urban tourism and cultural city/town planning andmanagement.

Full scale application of combined SBF-AS process for municipal wastewater treatment in small towns and cities in China

The combined submerged biofilm （ SBF）-activated sludge （AS） process for treatment of municipal wastewater in a small city in China is described in this paper. The process exhibited high removal efficiencies for carbonaceous substances, nitrogen and phosphorus which mainly took place in the combined SBF-AS biore- actor. The SBF-AS bioreactor was divided into pre-anoxic, anaerobic, anoxic and aerobic zones from inlet to outlet, in which fixed biofilm carriers were packed. Excellent performance had been obtained under normal operating conditions in more than one year of operation in Dong＇ e municipal WWTP, Shandong province, with mean removal efficiencies of BOD5 93.4%, COD 88%, SS 92%, NH4 - N 82. 1%, TP 75% and TN 66.7%, and quite high effluent quality such as BOD5 6 to 10 rag/L, COD 20 to 40 rag/L, SS 5 to 10 rag/L, TN 10 to 20 rag/L, NH4 - N 4 to 8 mg/L and TP 0. 6 to 1.0 mg/L. The effluent was reused multi-purposely, such as toilet flushing, green belt watering and artificial lake pounding. Simultaneous nitrification and denitrification took place due to the DO gradient in biofilm in aerobic zone of the SBF-AS bioreactor, which made TN removal efficiency improved remarkably in system. Some activated sludge was returned from final clarifiers to the bioreactor for phosphorus removal. The process had the advantages of low investment and low operational/ maintenance （O/M） costs, low sludge yield and was preferably employed in small towns and cities.

Bicycle Paths： A Way to Sustainable Mobility in Medium Sized Towns

Considering that non-motorized transport along with public transport are resourceful forms of mobility, this research aimed to investigate the serviceability of integrated bicycle path networks in towns of medium size. Factors impacting bicycle use in medium sized cities （urban planning, other transport means, adequacy of installations and parking spaces, etc.） have been examined. Bicycle can be something more than a sport or entertainment activity and has the potential to become an efficient means of transport. Xanthi is a medium sized town in Northern Greece. Its total area is 153 km2 and 65,000 people live there. An analysis of the existing traffic schemes in the city has pointed out the necessity of an organized bicycle paths network both cost effective and time saving. The main characteristics of such a network are described, hoping that in its completed form could impose the features of sustainable mobility and would be a paradigm for mid-sized cities in the country. Cars could be kept out of the central part of Xanthi ifa bicycle paths network is built using a ring-like scheme, since the residents favor the use of bicycle. Local authorities＇ plans must encourage the lending of public owned bicycles.

Sustainable Development Research in Chinese Medium-Sized City Based on SLEUTH

Compared with megacity, the medium-sized city is playing a more and more important part in the rapid urbanization process in China. Due to the expanding scale of the medium-sized city, urban growth is sprawl and this way leads to ecological, social and environment problems that are unsustainable. To measure the urban growth of the medium sized city, cellular automata (CA) model is employed. CA has proven to be a popular and effective modeling approach to investigate dynamic urban growth systems and for evaluating the impacts of possible policy options. We use the SLEUTH model, which is a well known CA model, to simulate the future urban growth of Huaian, Jiangsu province of China. The results confirm the value of SLEUTH which provides a rich exploratory of knowledge for evaluating the effects of possible decision-making in local government.
