  3. There was a positive correlation between protein content and average daily temperature and average sunshine time during heading to maturation, but a negative correlation existed between protein content and average diurnal variation of temperature in this period

    蛋白質含量與抽穗成熟期間的平均日均溫和平均日照時數呈正相關，與平均晝夜溫差呈負相關。
  4. The main results indicated that : significant differences exist in diurnal average transpiration rate and the range of diurnal transpiration rate ; the transpiration rate of sawtooth oak, amorpha, lalang grass varied with a regular double apex rhythm, but that of the rest varied with a regular single apex rhythm, stomatal conductance play a maximal important role in transpiration rate, temperature ( air temperature, the earth ' s surface temperature ) also influence the transpiration rate ; transpiration rate has prominent negative correlation with the relative air humidity, the biggest coefficient is 0. 866

    筆者對日照沿海防護林幾種主要木本植物和草本植物的蒸騰速率和環境因子的關系進行了研究，結果表明： 8種植物日平均蒸騰速率和蒸騰速率日變幅各異；麻櫟、紫穗槐和白茅的蒸騰速率日變換呈現出雙峰式的變化規律，其它5種植物蒸騰速率表現為單峰式的變化規律；氣孔導度影響著植物的蒸騰速率，溫度（氣溫、地面溫度）是影響植物蒸騰速率的主要因子；空氣相對濕度和蒸騰速率表現為顯著或極顯著負相關，相關系數高達0 . 866 。
  5. ( 3 ) the diurnal observation results of soil co2 dynamics in the field display the variation of soil co2 concentration and the releasing rate of co2 coming from soil surface is controlled by temperature. the correlation between co2 concentration in the top soil and temperature is very significant

    （ 3 ）土壤co _ 2濃度和土壤釋放量晝夜動態變化均受溫度控制。土壤co _ 2濃度中義摘要變化與溫度相關分析結果表明，土壤表層co 。濃度的變化與溫度相關性顯著。
  6. 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。
  7. The character of surface radiation and energy expended over soil temperature variation is that the temperature variation at surface, 5cm depth and 10cm depth are approximately sine curve on clear and cloudy day while this way the temperature variation at 20cm depth shows small extent anti - phase variation and the temperature under 50cm is no diurnal. in contrast, the temperature at 5m, 10cm and 20cm shows linear decrease and the soil - surface temperature is concaved on rainy day

    地表輻射和能量耗散反映在土壤溫度變化上的特徵是晴天和陰天地表、 5cm 、 10cm的溫度變化表現為準正玄曲線， 20cm深處的溫度變化呈現出幅度很小的反位向變化， 50cm以下地溫已不存在日變化特徵；雨天5cm 、 10cm和20cm的溫度呈線性遞減，地表溫度表現出由降雨引起的凹陷現象。
