近50年衡阳烟区气候变化及气象风险时空分布特征
Temporal and Spatial Distribution Characteristics of Climate Change and Meteorological Risk in Tobacco-Growing Areas of Hengyang in Recent 50 Years
摘要
Abstract
In order to understand the spatial and temporal distribution characteristics of climate change and meteorological disaster risk in tobacco-growing areas of Hengyang,based on the meteorological data from 1971 to 2020 in 5 counties and cities of Hengyang tobacco-growing area,the temporal and spatial distribution characteristics of climate change and meteorological risk were quantitatively analyzed by linear trend analysis and correlation analysis.The results showed that in the past 50 years,the average field temperature in the tobacco-growing areas of Hengyang increased significantly,the fluctuation of precipitation increased significantly,and the average sunshine hours decreased significantly.The risk of low temperature was mainly concentrated in the elongation stage.The risk of low temperature in Hengnan County and Hengyang County was relatively high and had a decreasing trend in recent years.The risk of high temperature mainly occurred in the later stage of maturation.The risk of high temperature in the southern region,centered in Changning,was relatively high.The increase of high temperature risk in the mature stage was significantly positively correlated with the increase of average temperature,there was a significant negative correlation between the risk of high temperature and precipitation.The southern regions of Changning and Leiyang had a relatively high rainstorm risk with an increasing trend,which may be related to the increase of rainfall in the later stage of maturity.In Leiyang,the drought degree at the elongation stage was more obvious and showed an increasing tendency,while the drought risk was relatively higher at the peak-early maturity stage in Hengyang County and Qidong County,and the drought risk was alleviated in other counties except Hengyang County.Finally,several practical recommendations are proposed for production.Preventive measures should be implemented at different growth stages to address varying meteorological risks,mitigating the adverse effects of weather disasters on tobacco growth and quality.关键词
