Abstract:

There are complex interactions among climatic change, fire disturbance, and ecosystem productivity. Fire disturbance could change the biogeochemical properties of soil and ecosystem structure, nutrient cycle and distribution as well as atmospheric composition and then influence ecosystem productivity; additionally, fire-induced emission can change the atmospheric composition and hence impacts the climate system; climate warming could alter the properties of fuel load and increase the frequency of fire-weather, and then in turn, influences regional fire regime.

In order to evaluate the impact of global change on ecosystem productivity comprehensively, it is essential to fully understand this complex interaction.

In this paper, we have reviewed the mechanisms of the interactions among global change, fire disturbance, and ecosystem productivity. Four critical issues have been explored: 1) methods used for constructing time sequence of fire information, 2) interaction between fire disturbance and global climate change, 3) interaction between fire disturbance and ecosystem productivity, and 4) changing fire management strategy in response to global change.

The comprehensive understanding of the complex interaction will be an important basis for further study how ecosystem pattern and process respond global change.

Key words: global change, fire disturbance, ecosystem productivity, fire management
