Urban Microclimates in Chongqing

Project Overview

This project will collect original microclimates data in Chongqing, including air temperature, humidity and wind speed. We will analyse the trends of urban microclimate changes by collecting historical data from the annual national statistic book. Satellite Digital Image technology will be applied along with mathematical modelling to study the urban heat island. The research output will be useful to urban planning and sustainable development in the built environment.

Background

The environmental impact of the Three Gorges Dam construction project in China has attracted international attention. The reservoir was completed in October 2010 and the water has risen to the designed level of 175m. The project generates electricity to relieve energy burden but it also causes environmental impacts on surrounding areas. Chongqing, with a population of more than 31.4 million, is the biggest municipality in China, and is located in the upstream of the Yangtze River. Over the past decade, Chongqing has experienced a great influx of migrants from the Three Gorge Reservoir region. It has also undergone major urban development and continues to attract overseas interest in terms of business development, including from UK construction companies. This urbanisation in the region has caused massive environmental impacts including urban microclimates and air/water pollution.

Key Objectives

  • To review the most up-to-date research information about the environmental impact of the Three Gorges Dam construction project;
  • To collect historical data on the local climate including temperature, humidity and wind speed;
  • To monitor the urban microclimates including air temperature, humidity, wind speed, etc. in Chongqing;
  • To compare the collected data with historical data and analyse the variation trends of the local climates;
  • To study urban heat island and mitigation and adaptation in building design and urban planning using a digital simulation method.
