Abstract: A project of applications of multivariate statistical analysis in forestry and its software packages has been engaged for six years. Three achievements, a book and two software packages have been submitted.1.The book "Methods of multivariate statistical analysis" was written to provide researchers, investigators and workers in forestry and agriculture with an elementary and important multivariate technique. The book includes many examples which have been employed in forestry and agriculture successfully.2.The IBM-PC program set consists of 90 programs, which involve statistics, programming and management. The set not only includes usual data transformations, statistical and multivariate analysis programs but also has some powerful programs, e. g. general multivariate nonlinear regression and general ANOVA. All the programs are easy-to-use and source programs are provided.3.OPMA (MAtrix Operator) is a software package for dealing with matrix operation. OPMA makes matrix operation easy. It is a useful tool to compute matrix and suitable for the students to learn matrix operation and computing methods of maltivariate analysis.
