规模化猪场甲烷排放通量测量与分析

Measurement and analysis of methane flux emitted from animal manure lagoon of livestock farm

畜禽粪便是温室气体甲烷排放的一个重要来源,养殖场蓄粪池的甲烷排放量受排入粪便性质、外界温度、风速以及诸多因素影响。为了研究中国北方规模化猪场蓄粪池的甲烷排放潜力,本研究通过对北京市北郊一个代表性猪场甲烷排量的连续监测,得出春夏交替期间蓄粪池甲烷排放的变化规律。

Methane(CH_4) emissions from animal breeding have become a concern.The concentration and emissions are affected by animal manure characteristics,air temperature and water temperature,wind speed and the other factor.To investigate CH_4 emissions from animal manure lagoon of livestock farm appropriate for China specific management method and climate situation,the CH_4 concentration and related information were measured in Beijing north during 2006.4～ 2006.8,the experimentation is still in progress.Some useful...
