Abstract
In our study, five stations of Poyang Lake were selected: Nanchang, Boyang, Jingde, Lushan and Jing’an. The three observational values of temperature, precipitation and evaporation in these five stations from 1988 to 2017 were analyzed. Through average, extreme value, linear regression and cumulative anomaly analysis, the interannual temperature variation trend of the five stations is consistent and is expected to continue to rise over the next 20 years; precipitation shows different changes in different periods; evaporation is decreasing year by year. This study is of great significance to the maintenance of ecological function and security of Poyang Lake.
