Fragmentation is often used to describe spatial structure of earth landscape ecology.This paper introduces the fragmentation in remote sensing sampling survey

and focuses on the application of area-scale and fragmentation in the stratified sampling.Experimental results show that:（1） in the regions with broken planting structure

correlation coefficients of area-scale and fragmentation are both above 0.7.Therefore

they both can be used as auxiliary variables for stratification design in such regions.With the increasing of sampling grids

correlation coefficient of area-scale increases

while correlation coefficient of fragmentation decreases.When sampling grid size is smaller than 100m×100m

fragmentation is better than area-scale.（2） in the regions with regular planting structure

area-scale is always better than fragmentation.Fragmentation is more suitable for the application of winter wheat area sample survey in regions where planting structure is broken

sampling units is small.
