The invention relates to a distribution network evaluation method based on power supply partitioning features. The method comprises the following steps: determining a distribution network evaluation index system which is composed of five primary indexes and 17 secondary indexes; building membership functions of the indexes by use of a fuzzy membership degree method and based on the principle of linear interpolation; determining the weights of the evaluation indexes by use of a judgment matrix method of a quantitative calculation method; establishing a direct influence matrix, calculating a comprehensive influence matrix between the indexes, and using the comprehensive influence matrix to optimize the weights of the evaluation indexes; and substituting the calculation result of the previous step to a calculation formula of the analytic hierarchy process to get the final result of distribution network evaluation. Through the method, the comprehensive score level of evaluation samples can be given more accurately, the evaluation result is more accurate, and the distribution network plan and design decision work can be better guided.
