云南高原蒙自城市热岛效应分析

The Analyse of Urban Heat Island Effect in Mengzi of Yunnan Plateau

  • 摘要: 根据蒙自市和屏边县气象站1951-2002年52年的气象资料,分析了蒙自城市热岛变化特征.结果表明蒙自城市存在热岛效应且有逐年增大的趋势.通过分析得知,近10年来蒙自热岛平均强度为1.56℃,热岛春季最强,夏季最弱;一天之中热岛强度08时最弱14时最强.利用灰色关联度分析法,分析了影响蒙自热岛效应的主要气象因子,得出影响蒙自城市热岛效应的主要气象因子是风速.

     

    Abstract: This paper analyzes the changing characteristics of the temperature and rainfall of Mengzi according to the meteorological information obtained from the weather observatory in Pinbian County of Mengzi from 1951 to 2002.The results indicate that there is urban heat island effect in Mengzi and it is increasing year by year.Through the investigation,we know that the average intensity in Mengzi is 1.56 ℃.It is strongest in spring and weakest in summer.It is strongest at 08:00 and weakest at 14:00 in a day.This article uses gray connection analysis method to analyze the main weather factor which affects this urban heat island in Mengzi.At last,it comes to the conclusion that the velocity of wind is the main weather factor.
