[A simulation on the emerging of birth defects in China with Kriging interpolation method].
OBJECTIVE
To describe the regional patterns of emerging level on birth defects with simulated map by original studied and reference data.


METHODS
Based on geographical information system, Kriging interpolation method was used and some related environmental factors were drawn from geographic information system software.


RESULTS
The Kriging method had drawn continual and smooth map on birth defect emerging level and shown some clues with environmental factors.


CONCLUSIONS
Kriging method and advanced spatial statistical and analytical methods were helpful in public health studies while simulated map suggested the feasibility of sampled data on national disease surveillance and giving some useful clues to etiological analysis.
