The assembling analytical method which occurs in the amount classification is used as a tool. It has made the partition in the forest conflagration and climate in 27 counties and cities in the middle of Yunnan Province. The partition gives a scientific base to varied fire-proof departments for them to arrange fireproof forces. Therefore, it has an important significance in the forest fire-proof.
