The 7 indicators of large field mouse were analyzed by principal component analysis with total 88 individual＇s specimens which collected from reclaimed green land in,Qinghai province. All ana lyzed indicators were ordered on the first principal component axis and representative degree on growth of large field mouse determined. T.he results showed： the body weight and corpus weight were the most representative age indicators of large field mouse. On purpose of accuracy, practicability and convenience, we selected body weight as age indicator of large field mouse and classified to 5 age clas ses. All of the work would be powerful witness which could be used to find out population dynamics and provide effective control; in time. |
