本文在Odum的能值生态经济计量方法的基础上，建立了2004年中国农业生物质资源开发的系统账户，补充了前人对1978 - 2000年中国生物质资源开发的长期历史趋势的研究（Chen et al. 2006.中国农业的能值分析。农业，生态系统和环境115，161-173）。计算了2004年中国生物质资源总通量和开发指标，并与2000年进行了比较，以阐明中国农业作为生物质资源开发部门的最新状况。详细介绍了数据来源和算法，为生物质农业开发的生态经济相关分析提供了基本参考。(c)2007爱思唯尔有限公司保留所有权利。
On the basis of Odum's ecological economic measure of emergy as embodied solar energy, a system account of biomass resource exploitation by agriculture in China 2004 is developed in this paper, which supplements a former study on corresponding long-term historical trends during 1978 to 2000 (Chen et al., 2006. Emergy-based analysis of the Chinese agriculture. Agriculture, Ecosystems and Environment 115, 161-173). The aggregate fluxes and indicators for biomass resource exploitation in China 2004 are calculated and illustrated when compared with those for 2000 to elucidate the latest status of the Chinese agriculture as the exploitation sector for biomass resource. Data sources and algorithm are presented in detail as basic references for related analysis involving the ecological economy of biomass exploitation in agriculture. (c) 2007 Elsevier Ltd.
