Abstract

Based on the rainfall data of nearly 60 years in Tongchuan City, Shaanxi Province, China (the following abbreviated as tongchuan) the author makes a detailed study of the precipitation data in Tongchuan since the 21st century by a detailed study. the author makes a detailed study of the precipitation data in Tongchuan since the 21st century by a detailed study.In other words, the author researches standardized precipitation index in every year and reason in Tongchuan,in order to analyze standardized precipitation index and drought intensity in different years and season. The main conclusions were as follows:(1)in the past 60 years throughout a downward trend and change tendency rate was -4.2831mm/10a.(2)The drought conditions in the Tongchuan city has gradually increased since the 21st century, especially in recent years, the intensity of drought in winter has been increase slowly.
