北纬30度东经120度采样点日照时数及光合有效辐射比较数据

光合日照时数的变化率直接反映了植物在不同时间段内可利用光能的多少，从而影响植物的光合作用效率。光合有效辐射变化率能够反映植物在不同时间段内光合作用能量来源的变化情况。光合有效辐射变化率与植物的光合速率密切相关。当光合有效辐射增强时，植物的光合速率通常会提高，反之则降低。因此，通过监测光合有效辐射变化率，可以间接了解植物光合作用效率的变化趋势。通过掌握光合有效辐射的变化规律，可以合理调节作物的种植密度、灌溉量、施肥量等管理措施，以优化作物的生长环境，提高作物产量和品质。
1数据采集：根据气象学标准，设置专业气象采集点，采集实时日照及辐射数据，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年同期日照时数变化率和光合有效辐射变化率。

The rate of change in photosynthetic sunshine duration directly reflects the amount of available solar energy for plants across different time periods, thereby affecting the photosynthetic efficiency of plants. The rate of change in Photosynthetically Active Radiation (PAR) can reflect the variations in the energy sources for plant photosynthesis across different time periods. The rate of change in PAR is closely correlated with plant photosynthetic rates. When PAR increases, plant photosynthetic rates typically rise, and vice versa. Therefore, monitoring the rate of change in PAR enables indirect understanding of the changing trends in plant photosynthetic efficiency. By grasping the variation patterns of PAR, reasonable adjustments can be made to crop management measures such as planting density, irrigation volume and fertilization rate, so as to optimize crop growth environments and improve crop yield and quality.
1. Data Collection: In accordance with meteorological standards, professional meteorological monitoring stations are established to collect real-time sunshine and radiation data, with an hourly sampling interval and uninterrupted collection for 365 consecutive days per year.
2. Data Preprocessing: Denoise, optimize and fill gaps in the collected datasets.
3. Data Derivation: Compare the data collected at the same month, same day and same time in 2022 and 2023, and calculate the rates of change in sunshine duration and PAR of 2023 relative to the corresponding period in 2022.
