| Abstract: | We preliminarily applied principal component analysis to study the annual pro-cesses of river runoff,and took Qitai county of Changji Prefecture of Xinjiang asan example to make concrete calculation and analysis.We got the conclusion thatprincipal component method was a better one to study the annual variation of riverrunoff. |
