jailcd2017062: The Influence of Urbanization Development on Urban Climate and Its Improvement Strategy -Taking Beijing Area as an Example

Abstract

In recent years, China's rapid urbanization process brought economic benefits, but also brought a series of urban problems. The continuous expansion of urban scale has created many high-density areas, such as land tension, population density, also resulting in environmental pollution. Due to the large-scale development and construction of city, it has changed natural topography, and made underlying surface of city rougher, weakened the role of city's wind, cause some problem in urban climate and ecological environment. This paper analyzes urbanization development and urban scale expansion of domestic cities in recent 50 years, taking Beijing as an example. The climate data of Beijing, such as carbon emission, temperature, humidity and wind speed, were collected in recent decades to analyze the trend of these climate data to study impact of urbanization on urban climate and environment. At the same time as development of urbanization to Beijing has brought many climate problems, especially in haze and extreme weather-based weather. In the last part of the article, putting forward some improvement strategies to the existing environmental problems caused by high density of urbanization, we discuss that the measures of smart growth, organic evacuation and ventilated corridor can provide a reference for Environmental issues.
