Comprehensive assessment of irrigation water quality based on multiple connection coefficient
摘要
Abstract
The determination of boundary value in dividing index grade of irrigation water quality is uncertain. In order to judge the relationship between index value and grade standards precisely, irrigation water quality is evaluated with the method of multiple connection coefficient. The electrical conductivity, sodium adsorption ratio, Na2CO3, chlorine ion and boron were selected as evaluating indexes, the paper combined the rights of each index to determine multiple connection coefficient and used confidence criteria to judge the grade of irrigation water quality. The results were basically the same as the attribute comprehensive evaluation, artificial neural network and matter - element model in the example, and agree with the actual. This illustrated that multiple connection coefficient method is used to evaluate irrigation water quality is feasible.关键词
