This paper reported that Bellamya purificate was highly sensitive to environmental factors. The growth speed and spawning number would increase when the water temperature raised. The experiment showed that Bellamya purthcate could live normally when pH value was 4.0~9. 4, but the optimum value was 6. 0~7. 8. Bellamya purificate has strong ability to anti-dry. Only the losing ratio of water is over 30% would cause to die.When the total nitrogen content is over 5.53%, it will find nothing of Bellamya purificate,but they can live normally when the total nitrogen content is not higher than 3. 6%. Bellamya purificate can live in high polluted and middle polluted water regions.
