甘肃省各个农田参考作物腾发量分析数据

通过全自动小型气象站对甘肃省各个农田实时监测空气中的温度、湿度和风速等并每日上传即时数据，分析计算参考作物腾发量ET0，为农田水分盈亏分析提供数据支撑，指导农田科学灌溉和排水，从而提高作物的产量和质量。1、每天每半小时通过全自动小型气象站对甘肃省各个农田实时监测空气中的温度、湿度和风速等并每日上传即时数据。 2、数据处理 对采集到的数据进行去重、合并，按照区域分类、统计处理，得到太阳净辐射量（W/m²）、温度（℃）、风速（m/s）、饱和蒸汽压（Pa）、环境湿度（%rh）、大气压值斜率、空气湿度，基于这些参数利用以下公式计算参考作物腾发量ET0： ET0=0.408*每日太阳净辐射量*大气压值斜率/（大气压值斜率+（空气湿度常数*（1+0.34*风速）））+900*风速/（温度+273.15）*（饱和蒸汽压-环境湿度）*空气湿度常数/（大气压值斜率+（空气湿度常数*(1+0.34*风速）））。 3、数据应用：通过长期ET0数据跟踪与分析，实现对该区域农田的蒸发蒸腾监测，为灌溉和排水提供数据支撑，从而提高作物的产量和质量。

This dataset is developed to support farmland water surplus and deficit analysis, guide scientific irrigation and drainage, and ultimately improve crop yield and quality. It is established through real-time monitoring of agricultural environmental parameters across various farmlands in Gansu Province via fully automatic small-scale weather stations, with real-time collected data uploaded daily, followed by analysis and calculation of the reference crop evapotranspiration (ET0).
1. Monitoring and Daily Data Upload: Every half-hour throughout the day, fully automatic small-scale weather stations conduct real-time monitoring of air temperature, humidity, wind speed and other relevant parameters across various farmlands in Gansu Province, and the real-time collected data is uploaded daily.
2. Data Processing: The collected raw data is first deduplicated and merged, then subjected to regional classification and statistical processing to derive the following parameters: solar net radiation (W/m²), air temperature (℃), wind speed (m/s), saturated vapor pressure (Pa), ambient relative humidity (%rh), atmospheric pressure slope, and air humidity. The reference crop evapotranspiration (ET0) is calculated using the following formula based on these parameters:
ET0 = 0.408 × (Daily solar net radiation × Atmospheric pressure slope) / (Atmospheric pressure slope + Air humidity constant × (1 + 0.34 × Wind speed)) + 900 × Wind speed / (Temperature + 273.15) × (Saturated vapor pressure - Ambient humidity) × Air humidity constant / (Atmospheric pressure slope + Air humidity constant × (1 + 0.34 × Wind speed))
3. Data Application: Through long-term tracking and analysis of ET0 data, evapotranspiration monitoring of farmlands in the target region is implemented, providing data support for irrigation and drainage operations, thereby improving crop yield and quality.
