| Abstract: |
| in order to further extend the definition, expression formula, description of physical connotation and analysis and application of five-element effect full partial connection number,and the analysis and application of examples, based on the study of expression formula and physical connotation the three-element partial positive connection number and the negative connection number of three-element effect full partial connection number, the calculation formula of of five-element effect full partial connection number is put forward, then, with the help of the area of the trend curve of the partial connection number to further explain it, extend the range of the application, and apply it to the actual analysis of water problems, the results show that:There is a high degree of consistency between five-element effect full partial connection number and the five-element fourth-order full partial connection number for the dynamic analysis and evaluation of water resources carrying capacity in Sichuan Province, moreover, the five-element effect full partial connection number can more clearly reflect the development trend of the evaluation object, the calculation process is more simple,and the evaluation result is more reasonable and more in line with the physical significance of the partial connection number; the diagnosis of the vulnerability index of agricultural drought by the five-element effect full partial connection number is consistent with the actual situation, and the four indexes fluctuate greatly with the change of the year, and the four indexes have great influence on the comprehensive evaluation results of drought vulnerability. Through the application of the five-element effect full partial connection number in different cases, the more reasonable and credible calculation results are obtained,, as the first-order partial connection coefficient of the connection number, the five-element effect full partial connection number can more intuitively reflect the differences between samples, more profoundly reveal the trend analysis of the set pair events, make preparations for the follow-up prevention and control and management, and also have great application prospects in other similar natural risks. |
