12.	内蒙古天然与放牧草原温室气体排放研究王跃思纪宝明等 Ying yong sheng tai xue bao, 2003, Letnik: 14, Številka: 3 Journal Article 采用静态箱-气相色谱法测定内蒙古典型草原温室气体排放。结果表明，四类天然草原吸收CH4、排放N2O和CO2各自有其相对固定的季节变化形式，四类草原和大气交换温室气体通量的变化形式基本一致，受年度气候变化所控制，而土壤、植被类型、降雨量等天然因素和放牧强度等人为因素仅影响排放强度。与天然羊草草原相比，自由放牧降低了羊草草原对CH4的吸收和N2O排放，增加了CO2的排放。	Celotno besedilo Dostopno za: UL
