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 溫帶的半干旱、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,為了揭示半干旱、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,本研究采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。

Abstract : the generation and control of odorous gases in treating night soil sludge was exploited in this paper . the results indicated that high concentration odorous gases can be generated during whole process in treating night soil sludge . in order to control the secondary pollution of odorous gases , the authors put forward a new kind of deodorization process - combustion in methane boiler and absorbde in washer 文摘:對糞渣污泥處理處置過程中惡臭氣體的產生及控制進行了研究,結果表明,在綜合處理全過程的幾個主要階段都會產生高濃度的惡臭氣體,為防止惡臭氣體對環境造成的二次污染,提出采用沼氣鍋爐焚燒和洗滌塔相結合的除臭工藝,洗滌塔除臭只有在系統啟動、調試和沼氣鍋爐發生故障的情況下使用。
