Abstract: |
【Background】 In previous work, we studied the results of the first-order partial connection coefficient and the subtraction set pair potential of the connection number, where we considered the directionality of the difference coefficient i in the partial positive connection number and the partial negative connection number. 【Objective】The aim of this paper is to clarify the definition of the total partial coupling coefficient of the five element effect, determine its expression formula, describe its physical connotation, and evaluate its practical application in solving real water problems. 【Method】This paper uses the method of analogy analysis to determine the calculation formula of the total partial coefficient of the five element effect by analyzing the existing results of the total partial coefficient of the three element effect, and further explains the physical connotation of the total partial coefficient of the five element effect with the help of the area of the trend curve of the partial coefficient, and applies it to the actual analysis of water problems.【Result】 ①the results of the dynamic evaluation of water resources carrying capacity in Sichuan Province are highly consistent with the results of the full deflection coefficient of five element effect, and the full deflection coefficient of five element effect has the advantages of clearer development trend of the evaluation object, simpler calculation process, more reasonable evaluation results and more consistent with the physical connotation of the deflection coefficient; ②The diagnostic results of the five element effect partial coefficient on the vulnerability index of agricultural drought are consistent with the actual situation. The four indicators have great intraannual changes, and the impact on the comprehensive assessment results of drought vulnerability is more obvious.【Conclusion】 The proposal of the five element effect total partial coupling coefficient expands the research scope of the effect total partial coupling coefficient, and the application in different cases has drawn more reasonable and credible calculation results, which has a great application prospect in solving similar problems in natural risk research. |
