首先从森林火灾的成因和影响因素，对其孕育环境进行了深入分析；其次，对中国森林火灾进行危险性分类，共5个大区，27个亚区，并对森林火灾损失危险进行分析；接着讨论了森林火灾影响评价。

This article mainly expounded pregant environment of forest fire hazard in China, Severity and frequent of forest fire hazard, damageable danger of forest fire hazar, evaluation of rist of forest fire hazard and countermeaseure for forest fire act. It is major research that regions of risk potential for forest fire hazard in China have been regionalized starting with analysis of pregnan environment of that at first. Then according to six factors of fire risk counter-analysis have been made for every forest area in all country, which are burning character of dominant tree breed, dense grade of agriculture population and dense degree of road network, as well as during protection against fire monthly average precipitation, the mean temperature and the average wind velocity. Also the  comprechensive essessing rescarch have been programed integration with occured strong degree and frequent grade by fire hazard in the history. In the end due to three fire dang erous grades of large、middle、small, the all forest areas in our cuontry will been divided into five large regions, twenty-seven sub-region.The counter-analysis are performing on Chinese map with scole of 1/4000000. This the lease area unite of the counter-analysis in Check netwoek of 5×5 squeare mm on the map. Then the small check betwork of 5×5 squcare mm also would been marged large check network of 15×15 squcare mm to equal 60× 60 squeare km on the ground, which are making integrate evaluation of fire dangerous grades in order to examine oneself critically time and reduced work content, In the addition from really neccessary protectional work aganst fire, the administrative division of having forest county are regarded as the least regional unite of counter-analysis, which are making integate evalution of fire risk potential.
Regionalization of forest forest fire hazard risk in China are performing comprehensive evaluation mainly on the basis of forest fire dangerous grades in forest aress, output of industry and agriculture by everybody, income of evbody in agriculture population, cost of gone out fire hazard, and also these are making the regionalization according to three dangerous grades of forest fire damage.
