| Abstract: | Taking Shaanxi province as an example, analysis is made on the relation of changes of precipitation and air temperature, El-nino, La-nina and sunspot with crop diseases and insect pests. The results indicate that, in Shaanxi province, there is positive correlation between crop diseases and insect pests and atmospheric temperature changes. Climate condition is a primarily controlling factor of crop diseases and insect pests and their epidemic. El-nino, La-nina and sunspot activity are closely related with the occurrence or prevalence of crop diseases and insect pests. |
