TL;DR: Wang et al. as mentioned in this paper proposed a related method to predict the future of China's urbanization rate, and with the city to observe the first degree of urbanization development potential.
Abstract: From 2003 to date the beginning of urbanization in China is growing rapidly, China’s urbanization rate in 2003 was 40.53%. 2013, the urbanization rate reached 53.7% of the total urban population of over 700 million, an average increase of 1.28 percentage points per year to maintain a rapid growth trend. New urbanization in relation to the future development of the country road is very important. While on the surface, urbanization, China has reached the world average, but many contradictions and problems lurking behind the increasingly prominent. In this paper, related method to predict the future of China’s urbanization rate, and with the city to observe the first degree of urbanization development potential. The new study found that the process of urbanization exist three main problems: “urban dual structure”, land reform and rural community issues into the city after the elaborate, these three issues if not solved, will affect the healthy development of urbanization in China, so the end of the article make recommendations and countermeasures.

TL;DR: In this article, a sunny day with high temperature in the coastal city of Dalian in July 2013 as the research background, the WRF model was used to implement the urban climate numerical simulation.
Abstract: Taking a sunny day with high temperature in the coastal city of Dalian in July 2013 as the research background, the WRF model was used to implement the urban climate numerical simulation. The results showed that the sea breeze and mountain massif had a significant alleviated effect on the UHI ( urban heated island ); the center of UHI is located in golden triangle area of Ganjingzi District with the maximum UHI intensity reaching 5.6°C . Compared the simulation results with the data of meteorological station and the in situ observation, the paper finds that their change trend was consistent and the deviation was within the acceptable range. The correspondent overall planning strategies were also analyzed for the city.

TL;DR: Wang et al. as discussed by the authors analyzed the spatial and temporal dynamic characteristics of Wuhan urban green land and suggested enhancing ecological restoration efforts, ensuring the construction of core patches in urban areas, and protecting and increasing some important patches in a stepping stone pattern to optimize the quantitative and spatial layout structure.
Abstract: Although rapid urbanization has improved living conditions, progress has caused several environmental problems, and has posed a serious threat to regional sustainability. Hence, reducing the negative effects linked to rapid urbanization has become an urgent task. As a vital part of the urban ecosystem, urban green land connectivity is a significant criteria for assessing the sustainable development of urban ecology. This study selected the highly urbanized Wuhan city as a research area, and used the Landsat 5 TM images from 2005 and the Landsat 7 ETM+ images from 2000 and 2010. These images were combined by using the graph-based integral index of connectivity (IIC), probability of connectivity (PC), and the importance value of the patch to analyze the spatial and temporal dynamic characteristics of the Wuhan urban green land. The results showed the increasing area and the widening Wuhan green land. However, for the past 10 years, their patch structure has been uneven, and composed of several small and super-large patches. The IIC and PC of Wuhan green land tended to increase slightly, whereas the connectivity level of urban green land remained low. The value of the importance of the patch and its range are increasing. Some of its characteristics indicated north is better than south, rural is higher than urban, and the main urban area is lesser than the urban area. Results further suggested enhancing ecological restoration efforts, ensuring the construction of core patches in urban areas, and protecting and increasing some important patches in a stepping stone pattern to optimize the quantitative and spatial layout structure of urban green land.

TL;DR: In this paper, the authors examined the changes in the temporal evolution of the surface energy budget induced by urbanization known as the Anthropogenic Influence (AI) in modifying the urban climate of a tropical city using Weather Research and Forecasting (WRF) numerical modeling system.
