基于差异优化减法集对势的区域农业旱灾脆弱性评价与诊断研究
Assessment and Diagnosis of Regional Agricultural Drought Vulnerability based on Differential Optimization Subtraction Set Pair Potential
摘要
Abstract
[Objective]To accurately and objectively assess regional agricultural drought vulnerability and quantitatively iden-tify its key driving factors is a key task in current agricultural drought risk management and prevention.[Methods]Starting from the perspective of the physical connotation of mutual migration and transformation of connection number components,semi-partial connection numbers were introduced to thoroughly explore the completeness of the uncertain information in the difference degree term of connection numbers.The uncertain information in the five-element connection number partial identi-cal difference degree and partial opposite difference degree was integrated into the partial neutral difference degree,and it was more finely allocated by considering the potential for mutual migration at the micro level.A difference optimization subtraction set pair potential method was proposed,and a regional agricultural drought vulnerability assessment and diagnostic model was constructed.This model was then empirically applied in Bengbu City,Anhui Province,China.[Results]The overall trend of agricultural drought vulnerability in Bengbu City from 2001 to 2010 improved,with exposure and disaster prevention and mitigation capacity identified as the main driving factors,and 10 indicators of agricultural drought vulnerability were diag-nosed.[Conclusion]Compared with existing methods,the evaluation results obtained using the above method demonstrate higher accuracy,objectivity,and sensitivity,which can provide new perspectives and approaches for the assessment and diag-nosis of agricultural drought vulnerability in China,and help to formulate more targeted agricultural production policies and drought mitigation measures to support the high-quality development of agriculture.关键词
