Abstract: The assessment index system and standards of water resources renewability are established from a quantitative viewpoint.By using the projection pursuit,the genetic algorithm,the reverse S-shape curve and the assessment stardards of water resource reproducible ability,a new method for comprehensive evaluating water resource reproducibe ability,the genetic projection pursuit method (GPPM) is established,for which detailed steps are given,it is used to assess the water resources reproducible ability of the 9 administrative divisions along the Yellow River.The result shows that the water resources reproducible ability of the Yellow River is rather low.But the GPPM has visual,effective and well adaptative features,where the evaluation results are given with real number.It is a superior evaluation method to various water resource comprehensive evaluation problems.
