摘　　要：基于西安地区的西安市、户县、长安区及高陵区1961-2017年5-20cm逐月地温的观测资料,通过气候诊断、单位转换、误差校正、距平等数据处理方法,并结合小波分析和Mann-Kendall非参数检验等数据分析方法,形成《西安地区土壤浅层温度距平及突变数据集(1961-2017)》。该数据集包括西安地区土壤浅层温度:(1)年代距平、逐年距平、年季距平和逐月距平数据;(2)周期、突变及异常值数据。本数据集存储为.xlsx格式,由6个数据文件组成,数据量为546 KB。In this study,based on existing literature research and the monthly ground temperature observation data from 1961 to 2017 in Xi'an city,Hu county,Chang'an district,and Gaoling district,the Anomaly and mutation dataset of soil shallow temperature in Xi'an region(1961-2017)was developed through processing methods such as climate diagnosis,unit conversion,error correction,and distance equality data,and data analysis methods such as wavelet analysis and Mann-Kendall non-parametric test.The dataset includes:(1)chronological data,year-by-year flat data,average annual temperature distance data,month-by-month flat data;(2)periodic,mutation,and outlier data.This dataset is archived in.xlsx format and consists of 6 data files with a data size of 546KB.
