北纬30度东经120度采样点30CM深度土壤温度比较数据

30CM深度的土壤温度变化率能够反映土壤深层的热动态特性。与表层土壤相比，深层土壤的温度变化更为稳定，但同样受到太阳辐射、大气温度、土壤湿度等多种因素的影响。通过监测这一深度的温度变化率，可以了解土壤深层在长时间尺度上的热变化规律。 土壤的热容量和导热性是影响土壤温度变化率的重要因素。不同土壤类型和质地的热容量和导热性存在差异，导致土壤温度变化率的不同。因此，监测30CM深度土壤的温度变化率，可以间接评估该土层的热容量和导热性，为土壤改良和农业生产提供依据。1数据采集：根据气象学标准，设置专业气象采集点，采集30CM深度土壤实时温度数据，时间做到以每小时为间隔，全年365天不间断采集；2数据处理：将数据去噪、优化、补全；3数据加工：通过将2023年和2022年同一月份同一天同一时刻的数据进行比较，得出23年相较于22年同期30CM深度土壤实时温度变化率。

The rate of soil temperature change at a depth of 30 cm reflects the thermal dynamic characteristics of deep soil layers. Compared with surface soil, deep soil exhibits more stable temperature fluctuations, yet its temperature is still influenced by multiple factors including solar radiation, air temperature, and soil moisture. By monitoring this temperature change rate, the long-term thermal variation patterns of deep soil layers can be characterized.

Soil thermal capacity and thermal conductivity are critical factors affecting soil temperature change rates. Variances in thermal capacity and conductivity exist across different soil types and textures, leading to distinct rates of soil temperature change. Accordingly, monitoring the soil temperature change rate at 30 cm depth can indirectly assess the thermal capacity and conductivity of this soil layer, providing a scientific basis for soil improvement and agricultural production.

1. Data Collection: In accordance with meteorological standards, professional meteorological monitoring stations are deployed to collect real-time soil temperature data at a depth of 30 cm, with a sampling interval of 1 hour and continuous collection for all 365 days of the year;
2. Data Preprocessing: The collected data will undergo denoising, optimization, and gap-filling;
3. Data Derivation: By comparing the real-time soil temperature data at 30 cm depth collected at the exact same month, day and time in 2022 and 2023, the relative rate of soil temperature change at 30 cm depth in 2023 versus the corresponding period in 2022 is calculated.
