泥炭地的碳库被认为在气候变化中可能不稳定。本研究首次对俄罗斯北部泥炭地(61 56′ N,50 13′ E)不同微形态的CO2净生态系统交换、生态系统呼吸的CO2排放和初级生产总值的CO2吸收进行了研究。从4月25日到2008年10月20日植被期结束和第一次霜冻期间,在7种不同的微形态类型:矿化和降雨空洞,草坪和丘,分别使用封闭室技术测量CO2通量,以及位于矿化和降雨沼泽部分之间过渡区的苔草草坪。腔室通量测量的总数为5,517。在调查期间,含雨的丘和草坪是CO2的源,而空洞和含矿的草坪是CO2的汇。一些地块的苔草草坪和矿物质丘汇,而这些微形态类型的其他地块的源。的CO 2通量的特点是大的变化,不仅之间的缩微类型,但也在各自的缩微类型。在所有的微形态类型中,苔草、雨生和矿生草坪的CO2通量的变异性最高,这可能与植被组成和覆盖度以及地下水位的微形态内异质性较强有关。气温是影响CO2通量动态的主要因素之一.地下水位和绿色面积指数对同一微形态不同斑块内部以及不同微形态之间的CO2通量有很强的影响。
The carbon pool of peatlands has been considered as potentially unstable in a changing climate. This study is the first presenting carbon dioxide (CO 2) net ecosystem exchange, CO 2 efflux due to ecosystem respiration and CO 2 uptake by gross primary production over a complete growing season for different microforms of a boreal peatland in Russia (61 56′ N, 50 13′ E). CO 2 fluxes were measured using the closed chamber technique from the 25th April in the period of snow melt until the end of the vegetation period and the first frost on the 20th October 2008 at seven different microform types: minerogenous and ombrogenous hollows, lawns and hummocks, respectively, and Carex lawns situated in a transition zone between minerogenous and ombrogenous mire parts. The total number of chamber flux measurements was 5,517. Ombrogenous hummocks and lawns were sources of CO 2 over the investigation period whereas hollows and minerogenous lawns were CO 2 sinks. Some plots of Carex lawns and minerogenous hummocks were sinks while other plots of these microform types were sources. The CO 2 fluxes were characterised by large variability not only between the microform types but also within the respective microform types. Of all microform types, the Carex, ombrogenous, and minerogenous lawns showed the highest variability in CO 2 fluxes, which is probably related to a stronger within-microform heterogeneity in vegetation composition and coverage as well as in the water table level. Air temperature was one of the dominant controls on the CO 2 flux dynamics. Water table and green area index were found to have strong influence on CO 2 fluxes both within different patches of the same microform type as well as between different microforms.
