Abstract
Calculation method for daily agricultural water demand was put forward from the aspects of water demand of crop growing period . The daily agricultural water demand in China was estimated.Results showed that Northeast China Plain, North China Plain and middle and lower reaches of the Yangtze River plain were the concentration areas of agricultural water demand in China .Daily agricultural water demand in most areas was 1 million-5 million m3 , and in some areas even exceeded 5 million m3 .Daily agricultural water demand in most areas of South China was 2 million-5 million m3 , and in some areas even exceeded 5 million m3 .Daily agricultural water demand in Xinjiang reached 1 million m3 .关键词
