EMERGY analysis for sustainability evaluation of the Baiyangdian wetland ecosystem in China

Weiqing MENG, Cui HAO, Hongyuan LI, Meiting JU,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 2, Pages 203-212 doi: 10.1007/s11783-010-0015-6

Abstract: Methods of EMERGY analysis were applied to illustrate the wetland ecosystem, to evaluate the economicThe indicators for the integrated ecological and economic system, such as EMERGY yield ratio (EYR) (7.51), EMERGY investment ratio (EIR) (4.52), environmental loading ratio (ELR) (2.92), EMERGY exchange ratio(0.41), and EMERGY sustainable indicator (ESI) (2.57) were calculated, compared, analyzed, and discussed

Emergy evaluation of Cynoglossus semilaevis Günther in industrial recirculating aquaculture

Wang Feng and Lei Jilin

Strategic Study of CAE 2015, Volume 17, Issue 1, Pages 4-10

Abstract: preferably evaluate breeding effect and environmental sustainability of recirculating aquaculture mode， the emergyCynoglossus semilaevis Günther in industrial recirculating aquaculture was built to analyze the emergyThe results showed that： The environment emergy input occupied only 1.08 %， emergy yield ratio (EYR)was 2.433， emergy loading ratio (ELR) was 0.313 4， and emergy sustainable index (ESI) was 7.763， indicating

Emergy evaluation of polygeneration systems

WANG Lingmei, LI Zheng, NI Weidou

Frontiers in Energy 2007, Volume 1, Issue 2, Pages 223-227 doi: 10.1007/s00000-007-0030-x

Abstract: To expand the application range of the emergy evaluation method, an emergy evaluation index, which canreflect the particular feature of polygeneration systems, has been elaborated on the basis of energy and emergyconservation, guided by the fundamental principle of emergy analysis.The results showed that emergy evaluation indices are practical for comprehensively evaluating polygeneration
