Assessing streetscape greenery with deep neural network using Google Street View

The importance of greenery in urban areas has traditionally been discussed from ecological and esthetic perspectives, as well as in public health and social science fields. The recent advancements in empirical studies were enabled by the combination of ‘big data’ of streetscapes and automated image recognition. However, the existing methods of automated image recognition for urban greenery have problems such as the confusion of green artificial objects and the excessive cost of model training. To ameliorate the drawbacks of existing methods, this study proposes to apply a patch-based semantic segmentation method for determining the green view index of certain urban areas by using Google Street View imagery and the ‘chopped picture method’. We expect that our method will contribute to expanding the scope of studies on urban greenery in various fields.     

The patterns and driving forces of uneven regional growth in ASEAN countries: A tale of two Thailands' path toward regional coordinated development

Uneven development has long been a critical issue in geography and urban studies, leading to economically inefficient urbanization, environmentally unbalanced regions, and socially unequal livelihoods. As one result, primate cities and urban primacy form within a hierarchical urban system, to which urban and regional planning must positively respond. It is worth noting that Thailand has experienced a number of important urbanization issues related to developing countries, such as semicolonialism and internal colonialism. This study aims to investigate regional uneven development based on primacy theory and the rank‐size rule, which are common in most Asian and developing countries. We examined the urbanization processes in Thailand, from 2000 to 2015, by looking at factors of population, GDP, land use, transportation networks, and nighttime light, which provide very recent regional development patterns. The second set of analyses explained the degree of primacy among different provinces and their ranking hierarchies. By presenting the persistent disparities of contemporary urbanization in Thailand and exploring its driving forces, this study offers insights into planning and policy and underscores the importance of regional coordinated development for achieving sustainable urbanization in Southeast Asian countries.     

Optimization of Urban Opening Space Pattern Based on Landscape Ecology

City is a spatial synthesis which consists of various buildings and urban opening space.With the developing of the urbanization,the urban planning will directly influence the sustainable development of a city,and the optimization of the urban zone pattern is the main section of the urban planning.The urban opening space is the main part of the urban landscape with important eco-function.Due to its flexibility,the urban opening space is becoming the object of the urban landscape pattern.In this study,some ecological problems during urban development were discussed,and a series of strategies of urban opening space pattern optimization have been put forward based on landscape planning theories.     

Applying SLEUTH model for simulating urban growth scenario of Chongqing districts

Districts of Chongqing is selected as the study area, which has a rapid rate of urbanization and eco-environmental pressure. The fundamental data of this study is the remote images and urban planning images of Chongqing city in 1988, 1993, 2000 and 2007. After data processing by RS and GIS, model calibration is applied to obtain the best parameters for the SLEUTH model. Then, the SLEUTH model is used for the simulation of the urban growth over the past 20 years. On the basis, the SLEUTH model is applied to predict the situation of urban expansion of the region in the next 10 years. The simulation results show that the calibrated model has a higher simulated precision for the urban expansion of study area, and the pace of urbanization has become relatively rapid in the study area, which may be closely related to the current land planning, road construction, industrial structure and economic policy.

Sustainable urbanization in Southeast Asia and beyond: Challenges of population growth,land use change,and environmental health

As economic growth centres, the Southeast Asian cities feature high population pressure, unsustainable land use, environmental degradation, and large ecological footprints. It is difficult to manage environmental health and basic services for urban dwellers, and ensure optimum flow of ecosystem services in the context of rapid, unplanned, and haphazard urbanization. These challenges are particularly multifaceted in the developing countries of Southeast Asian region. This study, based on secondary sources, adopted multidisciplinary lenses, such as geographical information systems, socio‐economic perspective, and sustainability science to examine the population situation, land use change pattern, and drivers of environmental degradation in the Southeast Asian cities as well as the Dhaka megacity, and brought forth a fresh perspective to look into contemporary urban ecosystems, population dynamics, environmental health, and sustainability. It also focused on identifying the commonalities among the cities under study to create a common understanding towards promoting collaborative urban development. This study shows that the urbanization process in the Southeast Asia region is taking place mostly in an unplanned and haphazard manner. With little concern for nature, life‐supporting ecological systems, and the environment, urban spatial growth continues unabated. The data surveyed and discussed in this paper shows that the current style of urbanization in Southeast Asia can best be called unsustainable. The findings also suggest that the general wellbeing and welfare of the current and future generations in Southeast Asian cities as well as in Dhaka is at risk. The paper recommends concerted efforts towards making the urbanization process sustainable, including better urban planning, policymaking, and international and regional cooperation.

Land supply and urbanization strategy in the Yangtze River Delta region,China

China's urbanization rate is increasing beyond sustainable levels because it has increased by approximately 1% every year in the last 30 years. As an important part of urban development, the selection of an urbanization strategy has been the focus of local governments. As such, local governments play an important role in urbanization processes by coordinating land supply and population growth. Using the 2009–2013 panel data of 41 cities in the Yangtze River Delta (YRD) region, this research tests the relationship between land supply and population growth to explore the urbanization strategy adopted by local governments. Simultaneous equation models for land supply and population growth are developed in this research. Empirical results identify land supply as the cause and population growth as the effect. Findings suggest that local governments in the YRD choose an aggressive strategy in urbanization which treats land as a tool for accelerating the urbanization.
