Abstract:

Rice is the most water-intensive crop in China, and water footprint for rice production as a measure of the total water consumption of a crop in a certain range of time and space, can measure the water resources in rice production accurately. In this paper, the temporal and spatial characteristics of water footprint for rice production were summarized, and the driving factors behind the temporal and spatial characteristics of water footprint for rice production were analyzed. The existing problems and the prospect of future research were put forward.

Key words: China, rice production, water footprint, spatio-temporal change
