title: [Eco-geographic landscapes of natural plague foci in China I. Eco-geographic landscapes of natural plague foci].
abstract: OBJECTIVE
  To study the eco-geographic landscapes of natural plague foci, in China.
  
  
  METHODS
  According to the surveillance records on plague epidemics and the eco-geographic landscapes of natural plague foci based on the county level, the criterion for classifying the ecological geographic zone of Chinese natural plague foci was established.
  
  
  RESULTS
  12 types and 19 subtypes of eco-geographic landscapes on Chinese natural plague foci were identified.
  
  
  CONCLUSIONS
  Scientific basis for Chinese natural plague foci classification was provided.
