摘要: 文章以提高东三省用水效率为目标，构建农业水贫困指标体系，依据水贫困指数模型(WPI)以及主客观综合赋权法对我国2010~2020年东北三省36个市级行政单位进行农业水贫困测度，结果显示了东北三省农业水贫困的基本分布格局、水贫困时空演变格局。

Abstract: With the goal of improving water use efficiency in the three northeastern provinces, this article constructs an agricultural water poverty index system. Based on the Water Poverty Index Model (WPI) and the subjective and objective comprehensive weighting method, agricultural water poverty was measured in 36 municipal administrative units in the three northeastern provinces of China from 2010 to 2020. The results show the basic distribution pattern and spatiotemporal evolution pattern of agricultural water poverty in the three northeastern provinces.
