To investigate the use efficiency of agricultural water resources in Yunnan Province
an evaluation model of agricultural water use efficiency was established by selecting the resource use efficiency
economic benefit
ecological benefit and other related 15 indexes
combining genetic algorithm with traditional optimization method
and using the principles of projection pursuit regression(PPR)technique.The model was used to comprehensively evaluate agricultural water scheme of 16 2010
optimize the best projection direction of state variable index areas in Yunnan Province in 2000-2005 and obtaine each sample projection value
so as to classify of the agricultural and evaluate each water resources use and efficiency
area.The evaluation recult best reflects the contribution and directivity of each index and accords with plateau seasonal drought gion of the agricultural water resources status.
