为缓解江苏省农业用水压力,研究基于水-能-粮-土纽带关系视角,揭示农业用水量的时空驱动机制。在2013年至2022年的时间跨度中,对江苏省13个城市的数据进行分析,运用对数平均迪氏指数法(LMDI)将农业用水量变化分解为人口规模、单位用水量、土地使用情况、机械化程度、每人机械动力及农业就业结构六个因素。在时间维度上,机械效率和土地使用效率是主要减少因素,而用水定额效应,年均增加10.92亿t为主要增加因素。从空间维度上,苏南城市的节水主要依赖于机械作用,而苏北城市则显著地受到土地利用效应的影响,为制定区域农业节水政策提供科学依据。

To alleviate agricultural water use pressure in Jiangsu Province, this study, from the perspective of the water-energy-food-land nexus, aims to reveal the spatiotemporal driving mechanisms of agricultural water use. Over the time span from 2013 to 2022, data from thirteen cities in Jiangsu Province were analyzed. The Logarithmic Mean Divisia Index (LMDI) method was employed to decompose changes in agricultural water use into six factors: population size, water use per unit output, land use patterns, mechanization level, machinery power per capita, and agricultural employment structure. In the temporal dimension, mechanical efficiency and land use efficiency were the primary factors reducing water use, while the water use quota effect, with an average annual increase of 1.092 billion tons, was the major contributing factor to increased water use. From a spatial perspective, water conservation in cities in southern Jiangsu mainly relies on mechanical effects, while cities in northern Jiangsu are significantly affected by land use effects. This provides a scientific basis for formulating regional agricultural water conservation policies.
