摘要	为了探讨生物炭对土壤N2O和CH4排放影响的途径和机理,在综合评述前人研究的基础上,就生物炭对土壤N2O和CH4排放的影响因素、途径和影响机理进行了分析,提出了不同土壤的生物炭施用原则,并指出了今后生物炭研究应注意的问题:(1)明确土壤中2种温室气体排放特点,因地制宜地选择合适的生物炭类型;(2)注意生物炭的添加时机和用量;(3)目前学者所用的生物炭类型以及土壤种类不同,关于生物炭影响土壤N2O和CH4排放的研究结论不同。在这方面的研究工作还应在完善生物炭施用标准的基础上,继续进行生物炭还田的本地化试验验证,才能为生物炭对土壤N2O和CH4排放的影响得出更明确的结论。
其他摘要	In order to study the pathway and mechanism of biochar affecting soil N2O and CH4 emissions, based on comprehensive evaluation of published researches, the factors, pathway and mechanism that biochar affected soil N2O and CH4 emissions were analyzed, the principles of biochar addition in different types of soil were then proposed. The key problems that should be paid attention to in future studies were pointed out: (1) the characters of these two GHG emissions in soil should be explicited, the biochar type should be chosen according to the local soil conditions. (2) The time and amount of biochar addition should be reasonable. (3) Nowadays because of the differences of biochars and soil types that different scholars used, the research conclusions about the effects of biochar on the soil N2O and CH4 emissions were still controversial. In future, the more clear conclusions about the effects of biochar on the soil N2O and CH4 would be attained till the experiments of returning biochar into field according to the local soil type should be continued after the complement of biochar applying standard.
