City spirit is the soul of the city. The spread of city spirit not only could establish a civilized specimen for citizens, but also create a good cultural atmosphere for the city. Hefei residents’ perception of city spirit is extensive, and most of Hefei citizens consider the expression words of city spirit are very appropriate, which is enlightened, open-minded, actual and innovate. Great majority of Hefei citizens willing to support the propaganda and promotion of the city spirit, and they think the promotion of the city spirit plays a key role in the way of city’s development. In addition,significant differences in the perception of urban spirituality emerge among residents with different economic and social characteristics. There are four aspects about how to enhance the public perception of city spirit, which including increasing dissemination channels and means,strengthening guidance according to the difference of residents, encouraging participation of community residents, and building good atmosphere depending on the city’s advantages.

Changes in sea level along the coastal southeastern United States (U.S.) influence the dynamic coastal response. In particular, the Southeast Coastal Network (SECN) of the National Park Service (NPS) has exhibited evidence of fluctuations in sea level which caused coastal erosion. Airborne LiDAR acquired from NOAA for Fort Matanzas National Monument, Fort Pulaski National Monument, Charles Pinckney National Historic Site, and Cape Lookout National Seashore were analyzed to identify changes in both elevation and the spatial volume of unconsolidated sedimentary material in the coastal southeast over time. Areas that exhibited an increase (deposited material) or decrease (eroded material) in elevation were mapped across the study area from 2006 to 2018. Results indicate a quasi-cyclic process where unconsolidated sediment distribution and the morphodynamic equilibrium changes with time. The coastal zones are steadily oscillating between the process of erosion and deposition affecting the coastal geomorphological dynamic. The use of LiDAR for evaluating coastal sustainability and resiliency due to this environmental phenomenon is clear.

With the development and construction of the city, the urban development of the Macau Peninsula has entered an era of stock development against the background of the limited scale of urban land. With the shortage of land resources, the problem of unused land on the Macau Peninsula is coming to the fore. This paper mainly studies the problem of idle land in the Macau Peninsula, based on the urban development and particular historical background of the region, investigates and elaborates on its complex formation causes through the literature research method, and analyzes the spatial distribution characteristics of idle land in the current situation of the Macau Peninsula by using GIS technology. Based on the above research,suggestions are put forward to prevent and manage the urban vacant land problem in the future urban management and development of Macau.

Eco-efficiency is an invaluable indicator for the measurement of the relationship between production activities and environmental depletion. This study measures the tourism eco-efficiency of 30 provinces in China from 2005 to 2020 based on the super-efficiency SBM model, and explores its spatial-temporal evolution characteristics using the kernel density function, standard deviation ellipse, and center of gravity model. Then, the influencing factors of the tourism eco-efficiency in China are analyzed by Tobit regression model. The results show that the tourism eco-efficiency of China is generally fluctuating upwards, but has not yet reached the maximum production possibility frontier. The kernel density curve shows a unimodal-bimodal-unimodal pattern, while the inter-provincial differences have been decreasing and becoming more balanced. The center of gravity of tourism eco-efficiency is located at the junction of Henan and Hubei province and generally moves to the south (slightly to the southwest). Meanwhile, it is revealed that the level of economic development and the tourism eco-efficiency has a significant inverted U-shaped relationship. The level of economic openness, traffic conditions, and tourism eco-efficiency is positively correlated. The environmental regulations and industrial structure have a negative but limited impact on tourism eco-efficiency. Finally, recommendations and suggestions for policy formulation to promote quality and sustainable development of the tourism industry are put forward, such as increasing investment in ecological protection and governance in tourism development, improving capacity-building in allocating green and low-carbon technologies and resources, strengthening tourism infrastructure construction, and enhancing environmental governance systems and mechanisms.

Open space has various implications in urban development planning and has been integrated in recent urban planning approaches and practices in Nepal. The open spaces are not only important for (re)shaping the urban form but are also important for enhancing urban social life and disaster risk management, particularly for dense cities. As most of the cities in Nepal have been growing haphazardly, the cities lack sufficient open space. However, the value of open space in dense cities like Kathmandu has been recognized more after the Gorkha Earthquake 2015 as the open spaces were extensively used for risk relief, treatment, recovery, and rehabilitation during and after the earthquake. With this background, this paper presents the major planning initiatives in Nepal and discusses how recent urban plans have provisioned and initiated open spaces development by reviewing concurrent urban planning practices, particularly reviewing Periodic Plans, Integrated Urban Development Plan, Smart City Plan, and Land Development Plan. The development of open areas has not been given much attention in the earlier urban planning practice but recent urban development planning has emphasized with a special focus which is very important for sustainable and safer city development and is expected to address the current bulging urban issues of spatiality and sociability. Therefore, it is very important for integrating open space implications in city planning and such open space should be conceptualized according to the city’s geography, landscape as well as socio-cultural contexts.

Traffic volume information has long played an important role in many transportation related works, such as traffic operations, roadway design, air quality control, and policy making. However, monitoring traffic volumes over a large spatial area is not an easy task due to the significant amount of time and manpower required to collect such large-scale datasets. In this study, a hybrid geostatistical approach, named Network Regression Kriging,has been developed to estimate urban traffic volumes by incorporating auxiliary variables such as road type, speed limit, and network accessibility.Since standard kriging is based on Euclidean distances, this study implements road network distances to improve traffic volumes estimations.A case study using 10-year of traffic volume data collected within the city of Edmonton was conducted to demonstrate the robustness of the model developed herein. Results suggest that the proposed hybrid model significantly outperforms the standard kriging method in terms of accuracy by 4.0% overall, especially for a large-scale network. It was also found that the necessary stationarity assumption for kriging did not hold true for a large network whereby separate estimations for each road type performed significantly better than a general estimation for the overall network by 4.12%.

This paper traces the sixteenth-century addition and removal on maps of a bulge on the southern coast of Chile. Abraham Ortelius was primarily responsible for these changes and many cartographers followed his lead.Then, Ortelius rotated the coastline of Chile from northwest to north. Later, he dropped the latitude of the islands of San Pablo and Isla de los Tiburones down six degrees. He named the Amazon River “Río de las amazons.” Finally, he removed the cities with fake Native-American-sounding names along the Pacific coast of North America. The research underlying this paper examined over seven-hundred sixteenth-century maps made by sixdozen cartographers. This paper cites five-dozen maps by four-dozen cartographers. In the traceability section of this paper, this information was condensed into a traceability diagram, which shows the chronological flow of information among a score of cartographers. Using this information, this paper traced the influence of one cartographer on another: it showed who influenced whom. It showed the spread of knowledge. Ortelius was at the center of most of this knowledge explosion.

Landuse/Landcover (LULC) changes are recognised as some of the major causes of environmental problems like land degradation and climate change. To achieve sustainability, we need to properly understand such changes in order to have adequate information that will enable us to design and implementing measures to mitigate their negative impacts. Doing this particularly requires a proper understanding of how stakeholders perceive the changes in general and their drivers in particular. Unfortunately,not much is known for many areas about the perspective of landuse stakeholders on drivers of LULC changes. This paper reports the results of a study conducted to examine the perceptions of different landuse stakeholders on drivers of LULC changes in Abuja Federal Capital Territory, Nigeria.Questionnaire survey was utilised, involving 514 households across four settlements, 2 rural (Karshi and Orozo) and 2 urban (Nyanya and Karu) towns in the territory, which were complimented with Focus Group Discussions were conducted. The results obtained showed that urban dwellers are largely aware of drivers of changes in socioeconomic drivers (physical development on lands, more commercial complex development and more institutional development). Rural dwellers are largely aware of environmental drivers of LULC changes (bush burning, livestock overgrazing, collections of wood and medicinal plants,and agricultural expansion). It was concluded that there is the need to bring about a harmonisation of the perceptions of LULC change drivers by the rural and urban dwellers so as to bring about a common front understanding and responding to LULC changes in the study area.
