| Abstract: | To build an index system for suitability evaluation of crops virtual water flows in China,18 indicators were selected respectively from agricultural production security system,support system and water security system.By using AHP and projection pursuit model,we calculated suitability degrees of crops virtual water flows of 31 provinces(autonomous regions and municipalities) in China.It is shown that Jilin,Heilongjiang,Hunan,Shanghai and Beijing have higher suitability degree,while Ningxia and Xizang have lo... |
