以沼气工程为纽带的生态农业工程模式及其效益分析

以杭州市浮山综合生态场为例,介绍了以沼气工程为纽带的生态农业工程模式。分析了该场沼气工程的设计和系统结构及各组分之间的相互关系,以及1983～1993年该场社会、经济和生态效益的演变过程。结果表明,以沼气工程为纽带的生态农业工程模式,能实现资源的多层次利用,改善生态环境,取得显著的生态、经济和社会效益。

Biogas-Project-Linked Eco agricultural Engineering Model and Its Benefit Analysis

Taking Fushan Integrated Ecological Farm of Hangzhou City for an example, this paper introduced the biogas project linked eco argicultural engineering model. The design of the biogas project, the system structure and the relationships among the components of the integrated farm, and the development process of its social, economic and ecological benefits during 1983~1993 were analyzed. The results indicated that the biogas project linked eco agricultural engineering model could realize the multilevel utilization of resources, improve the ecological environment, and therefore achieve significant social, economic and ecological benefits.
