An effective sponge city construction evaluation system plays a crucial role in evaluating sponge city construction *** construction of a sponge city evaluation system still faces challenges related to incomplete index selection and unscientific weight *** studies have focused on the comprehensive assessment of sponge city construction in the early *** study constructed a scientific assessment indicator system and a quantitative indicator weight at all levels by literature review and statistical analysis methods from an objective *** demonstrate how to utilize our evaluation methods,three construction schemes randomly generated by MATLAB were evaluated under evaluation states of constant weight and variable weight,*** 3 had the highest score of 0.638 under the constant weight assessment,but it cannot practically be the final construction scheme due to the imbalance between *** to the constant weight assessment,a variable weight assessment can effectively balance the states of the evaluation index with changes in the decision *** the three schemes,Scheme 2 is the best choice with a value of 0.0355 under variable weight evaluation due to punishment and incentives in the variable weight *** concept of“punishing”a disadvantageous indicator and“motivating”an advantageous indicator increases the relative advantages of the indices,ultimately affecting the assessment results of schemes and leading to a more balanced *** study provides reasonable analysis and decision-making mechanisms to support decision-making and guide the scientific selection of a construction scheme.
