Dynamic Evaluation of Regional Agricultural Drought Vulnerability Based on Triangular Fuzzy Number and Connection Number Coupling by GUO Fang, CUI Yi, CHEN Menglu

“…Vulnerability assessment of agricultural drought system is of great significance to agricultural drought risk management and risk control practice.In order to quantitatively evaluate the vulnerability of agricultural drought in Bengbu City,an evaluation model of agricultural drought vulnerability is established based on the coupling method of triangular fuzzy number and connection number.Firstly,connection number of single index is calculated by set pair analysis method,and the dynamic difference coefficient of different indexes is determined by the analysis and value method,that is,different-grade standard thresholds correspond to different difference coefficients.Then,connection value of each single index is calculated by combining the opposition coefficient and is weighted to obtain connection value of each subsystem and comprehensive connection value of sample.Finally,vulnerability grade value of regional agricultural drought system is determined by functional relationship between sample comprehensive connection value and evaluation grade value.Moreover,the model based on triangular fuzzy number and connection number coupling is applied to evaluate agricultural drought vulnerability in Bengbu City.The results show that:The results of comprehensive evaluation method based on triangular fuzzy number and connection number coupling were consistent with the comprehensive evaluation method based on grey relational analysis and connection number coupling,cloud similarity evaluation method and fuzzy comprehensive evaluation method.Drought vulnerability in 2001—2003 was strong,close to 3.5,and that in 2004—2010 was moderate,around 3.On the whole,the vulnerability is improved,which show that the ability of Bengbu's agricultural system to resist drought vulnerability is gradually strengthening,and level of agricultural development is constantly improving.Therefore,it can provide a strong basis for the government to scientifically prevent and control drought risks and scientific researchers to conduct quantitative research.…”
