| Abstract: | Land ecological model system is set up by using systematic idea,and multi-factors are analysed quantitatively.In mathematical model of quantitative evaluation,land ecological types are divided by using cluster analysis of Q system,and position ratio of all ecological types are determined by using major composition analysis method. |

| Keywords: | Bashan reservoir area ecological evaluation Q type cluster major compositon analysis |
