This study selected 11 typical polders above the Xianghekou gate of the Chu River as alternative flood storage areas, collected and collated data such as flood storage area, volume, population, arable land area, GDP and other data in the polders as input data, and the output data are the scores of indicators evaluated by each polders with the optimization method of the layout of this study.
11 typical polders are Gaohong pike, Lixin pike, Rean pike, Gangli pike, Qugao pike, Chengjia pike, Sun Xiaoxu pike, Xiangcheng-Hanshandong pike, Xiaosuijiao pike, Arakusa a pike, Hongguang pike. The unit of flood storage area is square kilometers, the unit of volume is ten thousand cubic meters, the unit of population is ten thousand people, the unit of cultivated area is ten thousand acres, and the unit of GDP is billion yuan. The output data is unitless.
The source of data for this study is filled in by the water administrative authorities of Hefei City and Chuzhou City Water Resources Bureau in Anhui Province. There is a strong reliability.
Input data are collected for research; using the comprehensive scoring method, the score value of each indicator is first calculated, and then points are assigned to each assessment indicator according to the scoring criteria of different indicators (the maximum value of the scores assigned to each indicator reflects the importance of each indicator), and then the scores assigned to each indicator are added up to obtain the total score.
