| Abstract: | Using the projection pursuit technique,a comprehensive assessment model for regional agricultural eco-(environmental) quality is developed.Projection pursuit model can give a comprehensive assessment projection index based on the indexes of regional agricultural eco-environmental quality,and according to the value of projection index,a(reasonable) assessment result can be drawn and it is easy to do in practice. |
