The community productivity, structure and succession are significantly influenced by global climate changes. this study focused on soil respiration rate of stipa baicalensis grassland by using dynamic infrared gas absorbed method. we analyzed diurnal pattern of soil respiration rate and the influences of surface soil temperature and water content for this parameter, then compared the differences between day and night soil respiration rates, and explored the correlations between aboveground and underground biomass with the soil respiration
溫帶的半乾旱、半濕潤區草甸草原屬于過渡氣候影響下形成的植被類型，對環境氣候條件變化十分敏感，為了揭示半乾旱、半濕潤區草甸草原生態系統土壤碳素釋放規律及其對主要環境因子的響應，本研究採用動態室紅外氣體吸收法測定松嫩草甸草原典型群落? ?貝加爾針茅群落土壤呼吸速率，分析了土壤呼吸速率日變化規律及表層土壤溫度和含水量對土壤呼吸速率日變化的影響，比較了土壤呼吸速率的晝夜差異，探討了地上生物量和地下生物量與土壤呼吸速率之間的相關關系。 -
Plants partitioned more biomass to the underground parts at high irradiance and more biomass to leaves at low irradiance. biomass partitioned to roots and leaves of plants at intermediate irradiance went between those of plants at high and low irradiance. defoliation of plants led to an increased partitioning of biomass to leaves, but the results were different at different time
總體來說，在高光照水平下，植株加大了對根的生物量分配，在低光照水平下增加了對葉的生物量分配，中度光照條件下植株對根和葉的分配則處于兩者之間；葉組織損失使植株加大了對葉的生物量投資，不同處理階段結果有所不同；在低光照條件下，葉損失植株對葉的生物量分配顯著高於高光照下的葉損失植株。 -
