供暖期间太原市不同下垫面条件下温湿环境日变化特征

THE CHANGE CHARACTERISTICS OF TEMPERATURE AND HUMIDITY ENVIRONMENT UNDER DIFFERENT SURFACE CONDITIONS IN TAIYUAN CITY DURING HEATING PERIOD

本文以太原市为例,在供暖期间通过对太原市不同下垫面(五一广场、文瀛公园)以及在同一下垫面不同高度(0.3m、1.0m、1.5m)分别架设HOBO温湿度记录仪实地观测数据,然后利用计算机对所测数据进行分析对比找出下垫面对近地面气温与湿度影响的细微差异,得出太原市供暖期间不同下垫面条件下温湿度环境日变化特征。其特征主要表现为太原市供暖期间下垫面条件不同对城市内部温湿环境日变化特征影响有明显差异,在同一下垫面条件下不同高度的温湿度环境日变化特征也有明显差异。首先,不同下垫面的温湿度环境日变化趋势及同一下垫面不同高度的温湿环境日变化特征趋势均大致相同。但在下垫面不同、高度相同条件下,温度大体上呈现出广场>公园的趋势,湿度大体上呈现出公园>广场的趋势。在下垫面相同、高度不同的条件下,呈现出温度随高度递增、湿度随高度递减的趋势。

Taking taiyuan city as an example,the different underlying surface during heating in taiyuan city(wuyi square,wenying park),and in the same underlying surface different height(0.3 m,1.0 m,1.5 m),respectively,set up the HOBO temperature and humidity recorder field observation data,and then using a computer to analyze the test data comparison to find out the mat facing the subtle differences in the effect of the surface temperature and humidity,come to taiyuan city during the heating temperature and humidity environment under the conditions of different underlying surface characteristics. Its characteristic main performance for different underlying surface conditions during heating in taiyuan city has obvious influence on urban internal temperature humidity environment day change characteristics differences,on the same underlying surface variation characteristics of temperature and humidity environment under the condition of different heights also have obvious difference. First of all,the variation trend of the temperature and humidity environment on different underlying surfaces and the temperature and humidity environment with different height of the same underlying surface are all the same. However,under different conditions and height,the temperature generally shows the trend of > park in the square,and the humidity generally shows the trend of > square in the park. Under the condition of the same height and different height,the temperature increases with height and the humidity decreases with height.
