[Bio-geological temporal zonation and its agricultural significance].
Bio-geological temporal zonation can be defined as a subsistent spatial-temporal style that the organisms clip from a geographical zone to break through its limit, and extend their survival extent with the strategy of excluding the environmental period of time which is not suitable to live and intercepting it which is suitable. It is the consequence that organisms temporally adapt the heat distribution pattern caused by the rotation and revolution of the Earth. Bio-geological temporal zonation relies on spatial zone, and the zonation spectrum changes in different spatial zones and has different basal heat zone. It appears as spiral loop based on its own spatial zone, and implies temporally seasonal change of the heat. Similarly, bio-geological temporal zonation relies on the distribution process of water and heat under spatial and temporal scale. The component, range and hierarchy of zonation spectrum change with spatial and temporal scale, and organisms adapt this kind of change with different ecological strategy depended on different ecological strategy. Human being can tune up bio-geological temporal zonation only in small scale.
