摘 要：
基于对云南省13个州(市)25县(市)25个村的1225个样本农户问卷调查资料分析发现,当前约有1/4的样本农户没有使用自己的户用沼气设施,究其主要原因放弃牲畜饲养是最重要的一个方面。随着农户家庭经济结构及劳动力就业结构的转变,分别只有43.4%,14.9%和12.7%的样本农户饲养了牛、马、羊,有45.6%,36.9%和75.1%的样本农户分别饲养了仔猪、母猪和肥猪。而农户饲养母猪及肥猪与其户用沼气使用情况的相关性达到了0.354。这足以说明农户牲畜饲养对户用沼气的影响,应该引起政策制定者及沼气推广部门的高度关注。

摘 要：
Based upon questionnaire survey of 1225 sample households from 25 villages of 25 counties(municipals) of 13 prefectures in Yunnan province,the paper highlighted that it is about 1/4 of sample households gave up the use of their biogas facility. The key reason is that they gave up the livestock breeding,and so they lost raw material for the biogas facility. The survey findings showed us that with the change of households' economic sources and employment structure,there were only 43. 4%,14. 9% and 12. 7% of sample households feeding cattles,horses and goats respectively,and 45. 6%, 36. 9% and 75. 1% of sample households were feeding piglets,sows and fattening pigs. The Lambda correlation coefficient between number of pig husbandry and use of biogas digester is about 0. 354. All these findings mean that the situation of households' animal husbandry has become one of the key factors influencing the use of biogas digesters,which should be paid more attention by the policy-maker and technicians related to biogas development.
