中文摘要:针对农产品水足迹量化仅关注农田直接耗水,而忽略间接水足迹的问题,基于国际水足迹标准量化框架,结合生命周期法,构建考虑生产资料及其上游产品完整供应链、国际和国内贸易的农产品生产水足迹量化框架,计算2016年中国大陆省级行政区尺度小麦原粮及其初加工产品(面粉和麦麸)的生产水足迹,分析其耗水特征。结果表明:供应链视角下,全国平均小麦生产水足迹为4869m3/t,生产资料的间接水足迹占比为6%;面粉和麦麸生产水足迹分别为3781m3/t和11037m3/t;省级小麦及其初级加工产品生产水足迹的大小与构成存在显著空间异质性,福建省小麦生产间接蓝水足迹占比高达25%。研究结果可为全面解析区域间农业和工业用水投入内在联系,制定合理的配水方案、落实“以水定产”战略提供一定科学依据。

Abstract:The product water footprint (WF) is defined as the direct and indirect consumption of water resources in the process of product production. The complete water consumption of agricultural products includes the direct water consumption of crops in the field and the indirect consumption of relevant inputs in the crop production supply-chain. However, previous studies on the WF of agricultural products only focused on the direct water consumption in the field. Here, within the framework of WF standard quantification and life cycle method, a quantitative framework for the supply-chain based water footprint (SWF) of agricultural products production that indicated both indirect and direct water consumption along the raw material-to-product chain at an intra-national level was proposed. Then, the SWFs of wheat and its processed products (wheat flour and wheat bran) in mainland Chinas provinces in 2016 was quantified. Results showed that the national average SWF of wheat production was 4869m3/t, and the indirect WF related to means of production accounted for 6% of the total SWF of wheat. The SWFs of wheat flour and wheat bran production were 3781m3/t and 11037m3/t, respectively. There was significant spatial heterogeneity in the intensity and composition of the SWF of wheat and derived products production, and the contribution of the indirect blue WF of Fujian wheat to the total blue WF reached 25%. The results can provide a scientific basis for comprehensively analyzing the internal relationship between agricultural and industrial water input among regions and for formulating reasonable water resources allocation scheme and implementing the stratagem of “deciding production by water”.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
