内蒙古大青山天然白桦林生物量、生产力及固碳释氧价值研究

Biomass,Productivity and Natural Forest of Betula platyphylla in Daqing Mountains of Inner Mongolia and its Value of Carbon Sequestration and Oxygen Release

白桦林是大青山的主要天然乔木林,在大青山的生态环境中占有重要的地位。通过对天然白桦林生物量及净生产力的研究,计算出了不同龄组天然白桦林的年平均固碳释氧总价值,结果为:幼龄林(7 222.99元·hm^(-2)·a^(-1))·中龄林(6 750.50元·hm^(-2)·a^(-1))·近熟林(5 838.27元·hm^(-2)·a^(-1))。

Betula platyphylla,which is the main forest of the Daqing Mountain,occupies an important position in the ecological environment of the Daqing Mountain.Through studying biomass net production of natural Betula platyphyllaforest,the mean annual carbon sequestration and oxygen release value for natural Betula platyphylla forest at different age group was calculated.Result show that young forest of Betula platyphylla（7 222.99Yuan·hm^-2·a^-1）〉half-mature forest Betula platyphyllaforest（6 750.50Yuan·hm^-2·a^-1）〉near-mature forest of Betula platyphyllaforest（5 838.27Yuan·hm^-2·a^-1）.
