人为因素对西安市气候变化的影响
Study on Effect of Human Activities on Climate Change of Xi' an City
摘要
Abstract
Taking example for Xi' an city, this paper studied the influences of urban development on the regional climate changes based on the meteorological data of Xi' an city and its surrounding areas as well as the data of urban human activity indexes, and established the regression models of urban climate affected by human activity. The results indicated that the heat island intensity generally presented an inverse - U - shaped variation trend in Xi' an city since 1993, and the precipitation difference between Xian city and its surrounding areas narrowed gradually. Meanwhile, the simulative curves of correlation between human activity and annual, seasonal and July urban climate mainly showed an inverse - U - shaped variation, suggesting that the microclimate in Xi' an city was gradually close to that in surrounding areas. So at present the climate of Xi' an city is in a good transition period, and the environmental protection measures needed to be consolidated and strengthened in the future.关键词
