- 摘要:
- 为研究延边地区的冻土与气温变化的响应关系,利用1965—2018年延边地区季节冻土的逐月冻土深度、冻结初终日期、月平均气温等资料,采用气候倾向率、小波分析、Mann -Kendall 检验、Pearson相关系数等方法对其进行了分析.结果表明:①延边地区冻土深度呈逐年变浅趋势,冻结日数呈逐年缩短趋势,气温呈逐年升高趋势,三者的气候倾向率分别为-6.48 cm/10 a,-4.30 d/10 a, 0.26 ℃/10 a.②冻土深度存在着17～24 a、10～16 a和3～9 a的变化周期,其中以17～24 a为主周期.③冻土深度和冻结日数与年均气温呈显著负相关性,即气温每升高1 ℃,最大冻土深度减小19.24 cm,冻结日数缩短10.35 d.本文研究结果可为延边地区的生态环境保护以及工程建设和农业生产等提供参考.
- Abstract:
- In order to study the response relationship between permafrost and temperature change in Yanbian area from 1965 to 2018, the monthly frozen soil depth, freezing beginning and ending dates, monthly average temperature and other data of seasonal frozen soil in Yanbian area were used to analyze it by using climate tendency rate, wavelet analysis, Mann Kendall test and Pearson correlation coefficient. The results show that:(1)the depth of frozen soil in Yanbian area is becoming shallower, the number of freezing days is shortening, and the temperature is increasing. The climate tendency rates of the three are -6.48 cm/10 a, -4.30 d/10 a, 0.26 ℃/10 a.(2)There are three types of periodic variation of frozen soil depth: 17-24 years, 10-16 years and 3-9 years, of which 17-24 years is the main period.(3)There is a significant negative correlation between the frozen soil depth and the average annual temperature in Yanbian area, that is, when the temperature increases by 1 ℃, the maximum frozen soil depth decreases by 19.24 cm, and the freezing days shorten by 10.35 days. The results of this paper can provide reference for ecological environment protection, engineering construction and agricultural production in Yanbian area.
