庆阳市冻土人工与自动观测对比分析

Comparative Analysis of Artificial and Automatic Observation of Frozen Soil in Qingyang City

利用庆阳市8个基本气象站1968—2021年气象资料及2021—2023年自动与人工冻土对比观测资料,运用相关性分析、线性趋势分析、M-K突变检验等统计方法,分析研究了50多年来冻土的变化趋势、与气象因子的相关性及自动与人工冻土观测数据的差异性,为研究冻土平行观测效果提供参考依据。

Using meteorological data from 8 basic meteorological stations in Qingyang City from 1968 to 2021 and comparative observation data between automatic and artificial frozen soil from 2021 to 2023,statistical methods such as correlation analysis,linear trend analysis,and M-K mutation test were used to analyze and study the changing trend of frozen soil over the past 50 years,the correlation with meteorological factors,and the differences between automatic and artificial frozen soil observation data.This provides a reference basis for studying the parallel observation effect of frozen soil.
