沼气工程对生态畜牧业系统的影响

Impact of biogas project on ecological animal husbandry system

以周口村为例,对周口村生态畜牧业系统进行能流分析,评估了引入沼气工程对村生态畜牧业系统的影响。结果表明,在生态畜牧业系统中引入沼气工程,可以将生产过程中产生的废弃物进行物质和能量的转化,实现对资源的多层次利用,形成了系统内部物质的良性循环,改善农村环境,促进经济、社会和生态环境的协调发展。

Ecological agriculture is the efficient approach and necessary choice for agriculture sustainable develop- ment in China,and ecological animal husbandry system is the key content of ecological agriculture.Taking Zhoukou village as an example,energy input—output analyses of Zhoukou ecological animal husbandry system is dealed with and the impact on the village animal husbandry system by biogas project is estimated.The estimated results indicate that biogas project into ecological animal husbandry system can efficiently transform the waste produced during the agricultural production,realize the multilevel utilization of resources,establish substance positive circulation inside the system,improve the environment of rural area,and accelerate the coordinated de- velopment of economy,resource and ecological environment.
