基于可变模糊评价法的农业旱灾灾后恢复力评估研究--以河北省为例
Application of variable fuzzy assessment method to drought resilience evaluation:a case study of Hebei Province
摘要
Abstract
Taking into consideration the natural and social economic conditions,eight indexes including precipita-tion,multiple cropping index,yield per unit area,per capita yield,effective irrigation rate,labor force proportion,per capita income of farmers,and ratio of agriculture output to input,were used to evaluate agricultural drought resilience . By using analytic hierarchy process,the weight of each index was determined,and the variable fuzzy assessment model was used for 1 1 cities of Hebei Province .The results indicated that there were significant differences among cities,with Shijiazhuang showing the highest value of 4 .2329,Tangshan the second 4 .0046,and Zhangjiakou the lowest 1 .8079 . We also found that effect of influencing factors on drought resilience varied .Precipitation was the most influencing factor, and effective irrigation rate as well as per capita income of farmers and ratio of agriculture output to input also showed considerable effects .关键词
