应用能值分析法对临潼区的“猪－沼－粮”三位一体的循环农业、秸秆还田种植以及单一养殖进行能值流、能值的投入与产出以及能值指标进行横向对比分析，结果表明：“猪－沼－粮”循环模式的能值自给率（ESR）为0．005，比单一生猪养殖业提高了0．5％；系统净能值产出率（EYR）分别增加了10．84、5．43；系统可持续发展性能指标（EISD）分别增加了 5．81、5．03；环境负载率（ELR）分别降低了10．76、0．97；能值废弃率（EWR）比单一生猪养殖业降低了8．63％，该模式具有资源利用率高、低排放、环境压力小、系统可持续发展能力强等优点，是生态经济效益最佳的生产模式，适合在关中平原大力推广，但仍需加大现代科技的投入和对系统的经济开发利用，促进“猪－沼－粮”循环模式的进一步推广。

Based on the emergy analysis ,characteristics of the emergy flow ,the input and output of emergy ,and e-mergy index were investigated in the “pig-methane-grain” circular agriculture ,straw returning and single breeding .Hori-zontal comparison analysis showed that ,the ESR of the mode of “pig-methane-grain” was increased by 0 .5% compared with the single pig raising system ,while the EYR was increased by 10 .84 and 5 .43 ,respectively .The EISD was in-creased by 5 .81 and 5 .03 ,respectively .The ELR was decreased by 10 .76 and 0 .97 ,respectively .The EWR was 8 .63% less than that by the single pig raising .This was found to be the best production mode with optimal ecological e-conomic benefit ,low emission ,small environment pressure and sustainable development .This mode was also found to be suitable for general extension in Guanzhong Plain and its vicinities .To promote economy development and advance the popularization of “pig-methane-grain” mode ,modern technologies should be employed as well .
