摘要
采用对林外和林内小气候定位观测的实验方法,以天山生态站2005,2006年的观测数据为基础,从大气温度、大气相对湿度、土温、蒸发量、风向风速、辐射量和照度等因子对天山生态站区林外林内的小气候要素差异性进行分析。结果表明:天山云杉林对小气候要素的影响是非常明显的,林内大气温度、土温、蒸发量、辐射强度、光照强度要比林外小,而相对湿度比林外大。利用SPSS(V11.5)软件统计分析表明,天山云杉林对土温和蒸发量的影响比对大气温度和湿度的影响显著。
With the experimental ways of locating observation of the microclimate in and out of the forest,based on the observation data in Tianshan Forest Ecosystem Research Station from 2005 and 2006,this paper applies air temperature,air relative humidity,soil temperature,evaporation,wind speed,wind direction,solar radiation,and sunlight strength etc.to analyze the difference of the microclimate factors in and out of the forest of the Tianshan Forest Ecosystem.The results show: The influence of Tianshan Mountain on the microclimate factors in Tianshan Forest is obvious.The observations in solar radiation,air temperature,soil temperature,evaporation,wind speed,solar radiation and sunlight strength in the forest are smaller than that out of the forest,but the relative humidity is higher.With the analysis of SPSS(V11.5),it is concluded that the influence of Tianshan Mountain Spruce on soil temperature and evaporation is more obvious than that of the temperature and humidity.
