This paper synthetically summarized current research on terrestrial nitrogen cycle and soil nitrogen cycle, meanwhile, uncertainties of terrestrial nitrogen cycle were discussed. the global diversified ecosystem nitrogen and carbon storage was comparative thoroughly estimated through different life zone. the global organic nitrogen storage was estimate by the c / n ratio
Post等按照不同生物帶比較全面的估算了全球各種生態系統類型的土壤碳氮密度和含量， mcelroy等利用土壤有機碳儲量和碳氮比來估算了全球土壤有機氮儲量。 -
In the past 40 years, the great change of nutrient structure has lead an obvious effects on the jiaozhou bay ecosystem, the silicate cycling has received significant scientific attention. an improved method is applied to the study of bsi in jiaozhou bay, the relationship between bsi and the phytoplankton, nutrient and organic carbon were discussed, the bsi cycle was studied simply
在此基礎上，對膠州灣沉積物中的bsi含量進行了測定，同時測定了4個航次膠州灣水體中的顆粒態生物硅（ pbsi ）含量，結合bsi培養實驗較系統地討論了膠州灣生物硅與浮游生物、營養鹽和有機碳之間的關系。 -
In this homeostaticsystem, a great number of organic compounds are synthesized, transformed, and decomposed continuously ; together, these processesconstitute the major parts of the carbon cycle
在這趨于穩定的體系中，很多有機化合物不停地被合成、轉換、分解；這些過程一起構成碳循環的主要部分。 -
New achievements having been obtained in this field show that co2 participating in karst process in the epikarst dynamic system mainly comes from soil air co2 created by the organic carbon, in other words, although karst is a kind of biochemistric action in nature, distribution and transmit and cycle of carbon rely on changes of soil organic carbon. soil organic carbon is the greatest carbon storeroom. soil respiration emission of co2 is the most important passing entrance in carbon cycle of epikarst ecosystem
已有的研究表明：參與巖溶作用的co _ 2多數屬于土壤中生物成因，也就是說，盡管巖溶作用是一種自然界無機化學作用，但碳的分佈與轉移及循環仍以生物活動為紐帶的土壤碳積累為轉化中心，土壤有機碳構成系統最大的碳庫，土壤呼吸碳表現為該系統中最重要的碳流通途徑，因此進行土壤co _ 2濃度觀測及其影響因子分析是研究表層帶巖溶生態系統運行機制和全球碳循環的首要條件。 -
The effect of different fertilization patterns ( such as normal chemical fertilizer, maize straw and farm manure ) on soil respiration has been measured by the method of static chamber alkaline absorbing and the difference of soil carbon cycle has been analyzed by quantity. by studying the effect of different fertilization patterns on soil nutrients and yield, the sustainable fertilization patterns of farm ecosystem was explored, especially supply the practical direction and theory guiding for developing ecological agriculture and organic agriculture
本試驗在不同培肥模式下（常規化肥培肥、秸稈還田、農肥培肥） ，通過研究不同培肥模式對土壤呼吸速率的影響，定量分析比較各培肥模式下玉米田生態系統土壤碳循環變化差異；研究不同培肥模式對土壤養分和產量的影響，探討可持續發展的農田生態系統培肥模式，特別是為發展生態農業和有機農業提供理論依據和實踐指導。
