哈尔滨市郊八月不同下垫面人体舒适度指数日变化特征

Human comfort degree index diurnal variation characters in different underlying surfaces in Harbin suburb in August

文章以气温、空气相对湿度、太阳辐射三个指标为影响因子来研究哈尔滨市郊八月不同下垫面人体舒适度指数,运用温湿指数模型,获得人体舒适度指数值,分析人体舒适度指数在三种下垫面随各指标的日变化特征及通过SPSS因子分析并确定各指标对人体舒适指数的贡献度。结果表明,人体舒适度指数日平均值:旷地(24.21)>草地(24.09)>林地(23.21);舒适时间:林地(11h)>草地(2h)>旷地(1h);舒适度关系:林地>草地>旷地。因子分析各气候指标对人体舒适度的解释程度:气温(1.959)>空气相对湿度(1.041)>辐射(0.26);人体舒适度指数信息含量:气温(65.316%)>空气相对湿度(33.776%)>辐射(0.908%);气候指标对人体舒适度的贡献度:气温>空气相对湿度>辐射。

The article took air temperature,air relative humidity and solar three indicators as factors to research human comfort degree index.Thermal Humidity Index model was used to get human comfot degree index value.Human comfort degree index diurnal variation with indicators in three underlying faces was analyzed and the indicators to contribution of human comfort degree index was determined through SPSS Factor Analysis.The results showed that human comfort degree index diurnal average value was like this ground （24.21）grass（24.09）woodlands（23.21）,comfortable time was woodlands（11 h）grass（2 h）ground（1 h）.It showed that the comfortable relation was woodlands grassground.Indicators to the explanation degree of human comfort degree represent temperature（1.959） air relative humidity（1.041） solar（0.26） and the information content of human comfort degree index was temperature（65.316%）air relative humidity（33.776%）solar（0.908%）.It showed that the indicators to contribution of human comfort degree index：was like this air temperatureair relative humiditysolar.
