%X It is difficult to establish the mathematics model and to control the precision of the assessment models in the multi - index complex system of water resources development.In order to solve the nonunniformity indexes problem and to raise the model precision for water resources development level assessment,a new model,genetic projection pursuit interpolation model(GPPIM),is presented for water resources development level assessment by using projection pursuit,genetic algorithm,interpolation technique and lots of sample data from the assessment standards of water resource development level.And its detailed step is developed.GPPIM remarkably improves calculation accuracy.The results of case studies in Xian show that GPPIM has the features of direct,credibility and effective.It proves a good assessment method in both classifying and arrangement,and could be applied to various water resources comprehensive assessment issues.
