The technique estimates tension fire seasons on the complex natural and anthropogenic factors determining burn vegetation. For its technical implementation of geographic information system architecture is proposed,consisting of blocks of data collection and data preprocessing; storage, and calculation of the indicators index tension fire seasons and visualize their changes. The developed system is investigated tensions fire seasons in 17 municipalities in the Khabarovsk Krai and the Jewish Autonomous Region meteorological data 27 weather stations and information about regional vegetation fires airbase and the Far East with the help of space and NASA sites FSI «Avialesookhrana» from 1976 till 2012. It is shown that the stress index corresponds to the density of vegetation fires and can be used to identify trends in the characteristics of the seasons to develop long-term programs to modernize fire monitoring based on the predictions of climate change and socio-economic conditions in a particular territory.
