“…Road-influenced growth encourages urbanized cells to develop along road network, which simulates the impact of existing transportation infrastructure on urban growth. The mentioned four urban growth rules are performed sequentially in each growth cycle and are controlled by five growth coefficients [44], namely dispersion coefficient, breed coefficient, spread coefficient, road gravity coefficient, and slope coefficient. The relationship between the four growth rules and the five coefficients is shown in Table 1.…”

As uncontrolled urban growth has increasingly challenged the sustainable use of urban land, it is critically important to model urban growth from different perspectives. Using the SLEUTH (Slope, Land use, Exclusion, Urban, Transportation, and Hill-shade) model, the historical data of Hefei in 2000, 2005, 2010, and 2015 were collected and input to simulate urban growth from 2015 to 2040. Three different urban growth scenarios were considered, namely a historical growth scenario, an urban planning growth scenario, and a land suitability growth scenario. Prediction results show that by 2040 urban built-up land would increase to 1434 km2 in the historical growth scenario, to 1190 km2 in the urban planning growth scenario, and to 1217 km2 in the land suitability growth scenario. We conclude that (1) exclusion layers without effective limits might result in unreasonable prediction of future built-up land; (2) based on the general land use map, the urban growth prediction took the governmental policies into account and could reveal the development hotspots in urban planning; and (3) the land suitability scenario prediction was the result of the trade-off between ecological land and built-up land as it used the MCR -based (minimum cumulative resistance model) land suitability assessment result. It would help to form a compact urban space and avoid excessive protection of farmland and ecological land. Findings derived from this study may provide urban planners with interesting insights on formulating urban planning strategies.

Some Influences of Underground Coal Gasification on the Environment

Increasing energy costs and energy demand have renewed global interest in clean coal technologies. Underground Coal Gasification (UCG) is an industrial process that converts coal into product gas. UCG is a promising technology with a lot of health, safety and environmental advantages over conventional mining techniques. UCG carries risks to human health, agriculture and the environment. This article briefly analyzes the advantages and negative environmental impacts of UCG. It describes experimental objects, mathematical models as tools for simulation cases and it used coal from UCG experiments in Cigel, Barbara and Wieczorek mines to analyze the environmental impacts of UCG. The gasification converts the carbon in the coal to syngas and heat. We carried out a numerical simulation of the two-dimensional unstable heat conduction in the coal and overburden, with the aim of judging the influence of this heat source on the surroundings, including the surface. The results show that the temperature in the surrounding rock first increases and then decreases with time, the peak of the temperature curve decreases gradually, and its position moves inside the surrounding rock from the ignition point. A small amount of potentially dangerous syngas leaks from the UCG cavity and channels into vulnerable areas depending on working pressures. The danger of explosion and poisoning in vulnerable zones was evaluated by the simulation model. The results show that the danger is real but by monitoring and controlling the air in the vulnerable area it is possible to reduce this risk.

“…The authors in [5] demonstrate that the urbanization process affects climate at all scales. Several studies have shown strategies to minimize the impact of growth and of urban density on climate using urban planning as a tool to control land usage and coverage, as well as reduce the impact of the urbanization process [6][7][8]16,[22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The relation between the urbanization process and climate is complex.…”

The purpose of this article is to analyze urban form through the mapping of morphological indices, namely impervious surface fraction, building density, verticality, height/width ratio, roughness length, and porosity, to support urban planning in the city of João Pessoa, PB, in northeastern Brazil. The application of this study identifies and calculates such significant indices for the city’s urban space from a Geographic Information System (GIS) model. The spatial indices play notable roles in climate at different scales, developing guidelines to maximize environmental quality, promote improvements to thermal comfort, minimize the urban heat island in the city of João Pessoa, and provide relevant data (considering microclimate aspects), guiding decisions related to the planning process.
