%X Based on the season droughts and situation of rice cultivation in hilly region of southern China,the analytic hierarchical process theory is applied to establish a mathematical model and indicators system for evaluating the comprehensive benefits of water-saving rice cultivation patterns.The evaluation indictors system is proposed abiding by principles of being scientific,practical and concise.The indicators system includes three aspects that reflect the primary benefits of water-saving rice cultivation patterns;there are economic,social and eco-environmental benefits.The evaluation model and the indicators system were carried out to evaluate synthetically the comprehensive benefit of water-saving rice cultivation patterns.The three demonstration patterns of water-saving rice cultivation(the water-saving irrigation double cropping rice pattern,the double cropping rice pattern of flood-drought cultivation,and water-saving rice cultivation pattern of rice and rape rotation) in the native "863" special project and the conventional double cropping rice pattern were taken as research projects in seasonal droughts hilly region of southern China.The evaluation results indicate that the integrated benefits of the water-saving rice cultivation patterns were higher than that of the conventional double cropping rice pattern,especially of water-saving rice cultivation pattern of rice and rape rotation.Therefore,the application of water-saving rice cultivation pattern of rice and rape rotation has a promising future,and furthermore,the evaluation model can be served as theoretical evidence for the management of,as well as further research on,water-saving rice cultivation patterns in seasonal droughts hilly region of southern China.
