Based on forest biomass distribution,the entropy difference was used to calcuate the forest biomass distribution cntropy in soil-rock mountain area of North China,and the law that the value increases with forest growth and the increasing scales was analyzed.

Spatial data quality assessment indexes based on uncertain band model of error entropy;

Dynamic model checking method based on residual entropy;

Information entropy being fused in residual correlation analysis of dynamic model, this paper constructs a general diagnostic quantity named "residual entropy", which means the (amount) of information left in residual series, and indicates the approximation degree of residual to white noise.
