Abstract: Based on the results of survey, field experimentation and model calculation, from the rainfall use during crops growth stage, the time-sequence relationship between crops growth and rainfall distribution, water supply-demand balance, water ecological adaptability index and water use efficiency. Water ecological adaptability of crops in mountainous arid area in suburb of Beijing was evaluated through a case study in Yanqing county. Results showed that there were differences in rainfall use among crops, the order being: perennial alfalfaspring cornspring soybeanspring milletpotato. Spring corn, spring millet and spring soybean were superior to potato and alfalfa in coupling characteristics between crop growth and rainfall distribution. Water satiety rate and water ecological adaptability could be put in order of spring cornspring milletspring soybeanpotato. There were also differences in water use efficiency, the order being: spring cornperennial alfalfa spring millet spring soybean potato. The study results may provide theoretic basis for drawing up the cropping system in mountainous and arid area in the suburb of Beijing.

Key words: Mountainous and arid area, Water ecological adaptability index, Water use efficiency
