摘要
1.Introduction China’s rural areas have experienced a significant transformation in the past four decades.During the period 1978-2019,agricultural production increased at an average rate of 5.4%per year[1].Although China’s water availability per capita is only one fourth of the global average and the nation’s cultivated land is only9%of the global total,China’s increased agricultural production has largely met the food needs of one fifth of the world’s population[2].
