Abstract

Abstract: Logarithmic mean divisia index （LMDI） model and Tapio decoupling model were used to study the driving effects of agricultural water consumption change and the decoupling relationship between agricultural water use and agricultural economic development in the middle reaches of the Yangtze River from 2009 to 2019. The results showed that the industrial structure effect was the main driving factor for the decrease of agricultural water consumption in the middle reaches of the Yangtze River, and the economic income effect was the main inhibiting factor for the decrease of agricultural water consumption. The overall decoupling situation in the middle reaches of the Yangtze River was good, but there were differences among provinces within the region.The overall decoupling situation in Hubei and Hunan was relatively good, while the overall decoupling situation in Jiangxi was relatively general. The technology decoupling factor had the most obvious influence on the decoupling, and the income decoupling factor was the most important factor to restrain the decoupling.

Key words: agricultural water consumption, agricultural economic development, Logarithmic mean divisia index model, Tapio decoupling model
