This paper analyzed on temporal and spatial differences of the wheat water footprint in the Yellow River Basin during 1984-2013. The results showed: (1) GWF and BWF both decreased; (2) the GWF proportion rose from 25.7% to 35.7%; (3) the BWF proportion decreased from 74.1% to 64.3%; (4) the highest WPWF value occurred in the northwest of the Yellow river basin, while WPWF in the southeast was low. The research is conducive to adjust measures to local conditions by Analysis on temporal and spatial differences. Introduction Agriculture is a water-intensive business, accounting for approximately 70% of total water consumption . Facing contradiction of water supply and demand, reasonable assessment for agriculture utility is required so as to improving water use efficiency to guarantee the food security. In 2002, Dutch scholar Hoekstra A. Y. depicted that the cumulative virtual water content of all goods and services consumed by one individual or by the individuals of one country, called water footprint (WF). WF is a comprehensive assessment criterion that interpret both direct and indirect water consumption from consumers and producers with the information of use time, location and types of water source . The majority of crop water footprint researches have been conducted from a macroscopic perspective, taken the whole world or the entire country as an object, and fruitful results are mainly contributed to water footprint quantification [3]. However, few studies attached importance to the temporal and spatial differences of WF in a specific river basin, where had unique climatic conditions and geological environment. Water issues related to wheat production in Yellow River Basin are impacted by regional climate, financial condition and infrastructural construction, which may have intimate spatial correlation. Especially Yellow River Basin with a vast territory, there is a big difference in agricultural development among its interior zones. In this paper, winter wheat in Yellow River (zone 8 province to 29 regions basic on climate and topography, Figure 1) is the main objects. The temporal and spatial differences of the water footprint of wheat is analyzed. 3rd International Conference on Management, Education Technology and Sports Science (METSS 2016) © 2016.
