By using 11 indexes of statistics between 1996 and 2000 and canonic correspondence analysis (CCA) method, spatial differentiat ion pat tern of production structure (combinat ion and propo rtion of faming-livestock raising-forestry)is analyzed.First, independent variable group and dependent variable group of CCA are defined. Second, by apply ing CANOCO4.5 and CANODRAW4.1 software, the study area is divided into 5 types of production structure :farming, farming-to-livestock raising, livestock raising-to-farming, fo restry and livestock raising.Finally, through a discussion on the spatial dif ferent iation, the 5 types of production st ructure distributed from southeast to northw est are found to be farming, farming-to-livestock raising, livestock raising-to-farming,forest ry and livestock raising.
