城市化对局地气候的影响分析

选取位于中等城市城区的湖南省常德气象观测站地面气象观测资料和位于小城市城郊的湖南省临澧气象局地面气象观测资料，利用统计方法，对比分析了各气候要素的变化态势。结果表明：常德站和临澧站在气候变暖大背景下，平均气温和最低气温呈线性递增趋势，相对湿度呈线性递减趋势，且递增（减）幅度常德站大于临澧站。常德城市人口大幅度增加年的前后，气候要素变化存在明显的突变，且以气温、湿度最为剧烈，显现出明显的热岛、干岛效应。针对显现出的城市发展对局地气候的影响，提出了减缓城市化影响的初步建议。

Analysis of Influence of Urbanization on Local Climate

The paper compares and analyzes the change trend of climate elements of surface meteorological observation data of Changde Meteorological Observation Station,which in medium-sized city of Changde,and Linli Meteorological Observation Station,which is in small city suburb,with statistical methods.The result indicates the average temperature and minimum temperature have a linearly increasing trend,and the relative humidity decreases linearly in Changde and Linli stations in the condition of climate warming,and...
