Abstract:

As an index of abilities of response，resistance and adaptation to the change of environment，resilience，which play the same role with vulnerability (another attribute of hazardaffected body)，enriched and defined exactly the characteristics of hazardaffected bodies when it was introduced to the field of natural disaster.It is urgent to study on resilience，such as how to define natural disaster resilience，diagnose and evaluate it，because of little researches on them at present.Based on land use investigation data and home inquiry data，using mathematical analysis methods，the paper analyzed the relationship between agricultural drought resilience and land use structure，economic and educational conditions of farmers in Gaopai River watershed of Dingcheng district，Hunan province.The results show that，the physiognomy types and altitude decide the agricultural drought resilience on larger scale，and the location of the water sources and its saving capacity，the percentage of paddy and dry land，cultural level，annual net 〖JP2〗income，percentage of nonfarm income are the main influence factors of resilience.It provided a 〖JP〗demonstration case and theoretical basis for further understanding and quantitative evaluation on resilience.
