摘要
以热带地区三亚市为研究对象,基于2009—2023年三亚市6个气象观测站日降水量、日平均气温等观测数据,利用Thornthwaite Memorial模型等数理统计分析方法,研究三亚市气候生产潜力的时空变化特征。结果表明,近十五年来,三亚市年平均气温、年降水量和气候生产潜力分别以0.54℃/10a、-227.6 mm/10a、-67.4 kg/(hm^(2)·10a)的速率变化,仅气温的变化趋势均通过显著性检验。三亚市各分区的气候生产潜力年际变化存在较大波动,各分区的年最大值和最小值相差328.8~394.0 kg/(hm^(2)·a)。空间分布上,气温呈现西高东低、南高北低的分布特点;降水和气候生产潜力空间变化总体上呈东高西低、北高南低的分布特征。三亚市年降水量和年平均气温与气候生产潜力分别存在正向和负向的相关关系,其中降水对气候生产潜力的正向影响更为显著。
Sanya City in a tropical region was taken as the research object,based on the observation data of daily precipitation and average temperature from six regional automatic meteorological stations in Sanya City from 2009 to 2023 and using the Thornthwaite Memorial model and mathematical statistical analysis methods,studied on the spatiotemporal variation characteristics of climate production potential in Sanya City.The results revealed that in the past 15 years,the annual average temperature,annual precipitation,and climate production potential in Sanya City have changed at rates of 0.54℃/10a,-227.6 mm/10a,and-67.4 kg/(hm^(2)·10a),respectively,only the trends of temperature changes has passed the significance test.There were significant fluctuations in the interannual variations in the climate production potential,with a difference of 328.8-394.0 kg/(hm^(2)·a)between the annual maximum and minimum values.Regarding spatial distribution,the temperature was higher in the west and lower in the east,and higher in the south and lower in the north.The spatial changes in precipitation and climate production potential generally exhibited patterns of high values in the east and low in the west,and high in the north and low in the south.There was a positive correlation between annual precipitation and climate production potential and a negative correlation between annual average temperature and climate production potential in the Sanya region.The positive impact of rainfall on climate production potential was especially more significant.
