【 摘 要 】

For the pollution problem of the pig breeding scale, we took three indexes as evaluation criterion, including arable land per capita, the water resource per capita and per capita share of grain. Then SPSS was used to synthesized the natural resources supply indexes of the pig breeding scale. The results show that with the fast development of technology and the steadily rising of grain production, the natural resources supply indexes of the pig breeding scale are raising constantly.
