| 摘 要： | 分析了西藏当雄高寒草甸碳通量站4 a高密度小气候观测资料的净辐射、光合有效辐射,气温的年变化和日变化的规律,绝对湿度、相对湿度、风、大气压、土壤温度及湿度、土壤热通量的年变化规律.该地区具有明显的高原大陆性气候特征,光照强、日照长,太阳辐射和光合有效辐强;气温年较差小,日较差大;空气湿度小,较干燥,雨季和旱季分明,降水集中强度小;气压低,有常风;土壤温度年变化较小,土壤湿度和降水有明显的对应关系,降水节律是土壤湿度的决定因素.

| Abstract: | 4-years microclimate of alpine meadow of China Flux Station in Damxung on the Tibetan Plateau was analyzed.The monthly and annual variation of solar radiation,photosynthetically active radiation (PAR),air temperature,absolute humidity,relative humidity,wind speed,air pressure,soil temperature,soil humidity and soil heat flux were compared and analyzed.That climate of the Damxung alpine meadow is characterized by continental temperate feature,with strong solar radiation and PAR,radation hours,low seasonal va... |
