Tropical cities currently face issues of climate change resulting from rapid urbanization and the impact of urban morphological transformations on the microclimate. The analysis of urban physical forms and patterns is a realisticmethodfor quantifying these impacts. This work examined the impact of morphological transformations of an urban site in Wuhan, China, on the microthermal environment at different time periods. We also quantified and compared the impact of four urban site morphologies on ambient air temperature. The morphological changes of the study site were inferred from Google Earth images acquired at different time points in 2006 and 2013. ENVI-met simulation software was used to compare the changes in temperature at the selected site by specific date. The year- and time-based analysis of existing urban morphologies and their impact on the microurban thermal environment shows that the overall minimum and maximum values of morning and afternoon ambient air temperature are nearly the same for the 2013 and 2006 morphologies. The maximum temperature difference was observed in the afternoon (14:00), with an average difference of approximately 2 °C in the east. The findings of this research could provide a useful guide for optimizing the transformation of urban site planning and design and a suitable method for assessing the impact of built-up areas on the environment.

This paper identifies transformation of urban morphology, form and urbanization impacts on both city's form and ecological functions. It explores, in particular, the transformation of urban spatial configuration and their relationship with the ecosystem. Also, it addresses the question of whether urban form contributes to the sustainable ecological urbanism. The methodology aims to integrate existing urban form and ecological urbanism approaches to improve the ecosystem of future cities. The research demonstrates how one can transform a city into a sustainable ecological urban environment, using the integrated approaches. The synthesis between urban form and ecological urbanism are able to produce ecologically sustainable urban environment.

The ecological functions of urban areas are degraded; the infrastructures of cities and the built have enormous impacts on ecosystems and ecology of the urban environment. In this paper, we focused on the connections of urban ecology and urban urbanisation impacts on urban ecosystems functions and ecological urbanism approach to degraded urban areas. The studies revealed the relationship of urban ecology and urban design and the ecosystem services they provide in the urban environment. I cities the impacts of urbanisation on ecosystem and ecology are various. Many cities in the world have implemented green infrastructure strategies for environmental improvement. Green infrastructure like green spaces, parks, gardens, and green bui provide ecosystem services to urban areas and can restore the ecological functions of urban areas. We proposed that Green infrastructure implications at urban design and buildings design level can lead to ecological-urbanism practices and can reduce environmental problems in degraded urban areas.
