中文摘要 | The framework of water consumption and water productivity (WP) is a useful approach for evaluating the performance of agricultural production systems and provides relevant feedback for management. The purpose of this research is to examine rice water consumption and WP in 56 counties of the Songnen Plain through integrating remotely sensed images, census data, and climatic records. The mean value and standard deviation (SD) of actual seasonal evapotranspiration (ETs) were 678.4 and 86.6 mm for paddy rice in the growing period (153 days) in the Songnen Plain, exhibiting a significant spatial heterogeneity. The WP ranged from 0.85 to 1.71 kg/m(3) with the WP mean value and SD being 1.26 and 0.23 kg/m(3). A comparative analysis of actual evapotranspiration (ETa), rice yield, WP, water stress, and rainfall maps indicates greater space for improvement of water use efficiency in the Songnen Plain, which will facilitates irrigation water resource management. |
