摘要
文章以乌鲁木齐南湖(观赏性湖泊)和幸福一号水库(灌溉水库)为例,对其夏季表层水体CH4和CO2分压[p(CH4)和p(CO2)]进行了监测,并分析了影响湖泊温室气体排放的水质参数。结果表明,乌鲁木齐典型水体对大气温室气体排放主要以CO2为主,CO2通量是CH4的2.29倍。pH、电导率、氧化还原电位与CH4、CO2通量显著相关(P<0.05),溶解氧、温度与温室气体排放通量不存在显著相关性。
In this study,Urumqi South Lake(an ornamental lake)and Xingfuyihao Reservoir(irrigation reservoir)were taken as examples to monitor the CH4 and CO2 partial pressures[p(CH4)and p(CO2)]for the surface water in summer.And the greenhouse gas emissions affected by the water quality paratmeters were analyzed.The results showed that the major greenhouse gas from the typical waterbody to the atmosphere was CO2,and the CO2 flux was 2.29 times than that of CH4.The parameters of pH,conductivity,redox potential were significantly correlated with the CH4 and CO2 fluxes(P<0.05),while there was no significantly correlation between dissolved oxygen,temperature and greenhouse gas emission fluxes.
