Abstract: The ecological classification of animal husbandry regions was a determined by a combination of the structure of species or kinds of livestocks and the feeding methods and management practices which possessed significant regional ecological characterisics.Complicated topography existed within Daoyuan County consisting ol different geomorphological types including mountains,hills and plains. The land elevation gradually decreased from south-west toward the east that caused apparent regional differences between the animal husbandry enterprises in each of the regions. The authors used cluster analysis by selecting five factor groups(topo-graphy , feed resources, carrying capacity, structure of stocks and poultry kinds)and 20 other factors. The regional ecological types of animal husbandry of Daoyuan County could be classified into three groups and eight subgroups according to these calculations. The first group consisted of swine, chicken, duck and rabbit production for the high plain regions; the second consisted of cattle,swine, rabbit, chicken and duck for the hilly region; the third consisted of cattle, sheep, rabbit, swine, chicken for the mountainous region. On the basis of such classification, the method of equal-effect coefficients Was used to make a comprehensive evalution of exploitation potential of each type of region. The results of evaluation indicated that the second group had the highest exploitation potential. It was determined from these results that animal husbandry should be further strengthened and developed for the hilly reglon and the structure of animal husbandry of the entire county should be readjusted.The proportion of herbivorous stocks should be raised and the pasture and feed resources of plant proteins should be fully exploited and utilized.
