- Abstract:
-
Through comparative analysis of suburb areas using statistical indicators of climate from 1959-2007, the dry island effect was characterized in urban Xi’an. With the introduction of mutation analysis and population of urban Xi’an over the years, we analyzed characteristics of seasonal variations and causes of the dry island effect in urban Xi’an of nearly 49 years. The results summarized as follows: years of Xi’an dry island effect showed a quadratic trend of sagging type, the lowest humidity down to -9%, mutations existed in 1992; the intensity of dry island effect of urban Xi’an varied with seasons, the strongest in spring, the second in winter, summer, autumn were the weakest. Xi’an dry island effect showed a strong linear relationship with population and the urban development in spring had the biggest impact on the dry island effect. The research results can enrich the content of the regularity of Xi’an urban climate change, which can be applied to the urban planning and management directly.
