How does climate change influence regional stability

Abstract

Nowadays, different places have different region stability, which is influenced by lots of factors. In this paper ,it is aimed to analyze the influence of climate change on regional stability. several factors that may influence the region stability are proposed. Then Principle Components Analysis (PCA) was used to select the most relevant factors. After that ,a BP neural network is established considering all the principle components to evaluate the Region Stability (RS). Subsequently, the specific influence of the climate change is analyzed and the results showed that long term average precipitation is a main climate factor influencing the RS.
