摘要
气候变化是当前全球关注的热点问题,为了进一步研究常德市近70年气候变化特征,选择1951-2020年间该站点监测地区的最低气温、最高气温、平均气压、平均气温、平均水气压、平均相对湿度6个气候因子为分析对象,运用时间序列分析、方差分析及线性回归等方法分析了常德市近70年气候变化状况.研究结果表明,常德市在近70年内各气候因子在时间上均存在上下波动情况,最低气温、最高气温、平均气温总体呈上升趋势,平均气压、平均水汽压、平均相对湿度呈下降趋势,平均相对湿度的下降幅度均高于其他气候因子.
Abstract
Climate change is currently a hot topic of global concern.In order to further study the characteristics of climate change over the past 70 years in Changde City,the six climate factors of minimum air temperature,maxi-mum air temperature,average air pressure,average air temperature,average vapor pressure and average relative hu-midity in the monitoring area of the station from 1951 to 2020 are selected as analysis objects,and time series analy-sis,variance analysis and linear regression methods are used to analyze the situation of climate change over the past 70 years in Changde City.Research results show that in the past 70 years,various climate factors in Changde City fluctuated up and down in time,minimum air temperature,maximum air temperature and average air temperature showed an overall upward trend,average air pressure,average vapor pressure and average relative humidity showed a downward trend,and that the decline range of average relative humidity was higher than that of other climate fac-tors.
