福建省各农田五层土壤THI分析数据

采集福建省各农田的五层土壤温度和土壤湿度数据，分别分析不同深度的土壤温度湿度指数(THI)。THI是描述土壤中温度和湿度状况的重要指标，可以为农业生产、植物生长监测和灾害预警等领域提供重要的参考数据；而五层土壤检测是对土壤进行多层次、综合性的分析和评估，五层土壤THI监测可以全面了解土壤的性质、质量、污染状况和环境特征，为土壤管理、农业生产和环境保护提供科学依据，有助于实现可持续农业和生态环境的保护与改善。每日采集福建省各农田的土壤进行编号，从而取得不同土壤编号的五层土壤温度和五层土壤湿度数据，以计算福建省各农田不同深度土壤的温度湿度指数(THI)，其计算公式为：THI = 0.8 × 温度 + 相对湿度 × （温度 - 14.4） + 46.4。 THI1、THI2、THI3、THI4、THI5分别表示表层土壤（深度为0-20厘米）、次表层土壤（深度为20-40厘米）、中层土壤（深度为40-60厘米）、下层土壤（深度为60-80厘米）和底层土壤（深度为80厘米以下）的温度湿度指数，根据上述公式可依次算出THI1、THI2、THI3、THI4以及THI5的值。

This dataset collects five-layer soil temperature and moisture data from farmlands across Fujian Province, and conducts separate analyses on the Soil Temperature and Humidity Index (THI) at various soil depths. THI is a critical indicator characterizing soil temperature and moisture conditions, providing essential reference data for agricultural production, plant growth monitoring, disaster early warning and other relevant fields. Five-layer soil testing enables multi-level and comprehensive soil analysis and assessment, while five-layer THI monitoring allows for a holistic understanding of soil properties, quality, pollution status and environmental features. This provides scientific support for soil management, agricultural production and environmental protection, and facilitates the achievement of sustainable agriculture as well as the conservation and improvement of the ecological environment. Soil samples from farmlands across Fujian Province are collected and numbered daily, to obtain five-layer soil temperature and moisture data corresponding to different soil sample numbers. These data are then used to calculate the THI values for soils at different depths in each farmland of Fujian Province. The calculation formula is: THI = 0.8 × Temperature + Relative Humidity × (Temperature - 14.4) + 46.4. THI1, THI2, THI3, THI4 and THI5 respectively refer to the THI of topsoil (0–20 cm depth), subsurface soil (20–40 cm), middle-layer soil (40–60 cm), lower-layer soil (60–80 cm) and bottom soil (below 80 cm). The values of THI1 through THI5 can be sequentially computed using the aforementioned formula.
