摘要：
The price and planting area data of three main crops in five regions of the Tarim River Basin from 2006 to 2017 were collected, and the planting area of wheat, corn and cotton were predicted by using the Nerlove model. In order to maximize the economic benefit of regional agricultural water use, the optimal allocation model of agricultural water resources is constructed by taking the predicted value as input data and considering the constraints of available water and the maximum and minimum irrigation water demand. The results show that the Nerlove model can well reflect the supply response relationship between most crops and price; the projected acreage for the three crops in the five regions in the planning year was positive except for the negative increase in corn in Hotan compared to the current year. The total amount of water distributed was 1. 856 22 million m3, and the spatial distribution was very uneven; the total revenue was 10.386 5 billion yuan. The more water distributed by crops, the higher the economic revenue was. © 2021, Editorial Board of Water Resources Protection. All rights reserved.
