| 摘 要： | 沼气工程是治理畜禽粪便污染的主要方法,可提供清洁能源,减少温室气体排放,减轻环境污染,具有良好的环境效益。本研究以湖南省洞庭湖区为例,利用《气候变化框架公约》清洁机制执行理事会批准的方法(ACM0010)和环境成本估算方法,分析了沼气工程对畜禽粪便污染的环境成本的控制潜力。结果表明,在湖南省洞庭湖区的畜禽粪便均采用沼气项目进行污染治理条件下,年出栏5 000头以上的生猪规模养殖场均进行沼气发电,其他畜禽养殖场的沼气全部用于畜禽养殖场及周边居民的供热和照明使用,则2006年可减排温室气体2 891 614 t CO2当量,减少温室气体排放环境成本为4.52亿元;同时,可减排水体污染、土壤污染、微生物污染控制的环境成本分别为4.56亿元、1.69亿元、5.32亿元。因此,要支持和鼓励养殖户利用沼气工程处理畜禽粪便,实现畜禽粪便污染治理环境效益、经济效益和社会效益的有机统一。

| Abstract: | As a main livestock and poultry fecal pollution management method, biogas project offers several advantages including clean energy, limited greenhouse gas emissions and environmental pollution. Using the Dongting Lake District (DLD) in Hunan Province as a case study, environmental cost control potential of livestock and poultry fecal pollution management via biogas projects was analyzed. The analysis was based on small scale CDM (clean development mechanism) project (ASM III.D-version14), approved by the CDM Executive Board under the United Nations Framework Convention on Climate Change and Environmental Cost Estimation Method. The results indicated that greenhouse gas emission was reduced by 2 891 614 ton equivalent CO2, and the environmental cost by 0.452 billion Yuan (RMB) in terms of greenhouse gas emission, provided that for the pig breeding farms with annual productions of 5 000 pigs, the biogas project was used to generate electric power in DLD; and for other pig breeding farms, the biogas project was used for heating and lighting in the surrounding residents in 2006. Concurrently, the reduced environmental cost of water pollution, soil contamination and microbial contamination was 0.456 billion RMB, 0.169 billion RMB and 0.532 billion RMB, respectively. It was therefore concluded that farmers with biogas projects (to manage livestock and poultry fecal pollution) should be supported and encouraged to achieve the environmental, economic and social benefits harmonically of livestock and poultry fecal pollution management. |
