Abstract
The biogas-linked agro-ecosystem plays a critical role in the sustainable development of rural China. In this study, emergy analysis was performed to assess the sustainability of a biogas-linked ecological orchard system in the Loess Plateau area. To analyze the system more comprehensively, the overall orchard system was divided into three subsystems, including the biogas subsystem, the greenhouse subsystem, and the orchard subsystem. Other than the conventional indicators, two novel indicators suitable for orchard ecosystems, the system production dominance and index of system stability, were developed to evaluate the overall performance of the system and subsystems. The results showed significant variations in multiple performances of the subsystems regarding resource utilization, renewability, and production capacity. The circulation of emergy flows among different subsystems revealed a promising renewable capacity and self-organizing ability for the overall system, which further suggests the advantage of this mode in terms of sustainability. As revealed by the emergy indicators, the biogas-linked ecological orchard as an ecological practice is feasible for modern agriculture involving intensive fruit production and breeding, as it can guarantee highly efficient resource recycling and energy conservation without destroying the local environment.
