农业生态运行性监测服务

1）长势监测。利用遥感参量评估农作物的生长形势、水热环境胁迫等内容，为田间管理和产量预期分析提供帮助。2）面积估算。利用遥感电磁波谱信息识别不同的农作物，估算农作物种植面积。3）产量估算。估算不同农作物的单位面积产量，并结合其面积大小估算总产量。4）旱情监测。利用卫星遥感的植被和地表温度信息，或土壤水分信息，建立旱情评估模型。确定旱情分布。受旱面积和受旱登记，并估算其对产量可能造成的影响。1) Crop Growth Monitoring: Use remote sensing parameters to assess crop growth status, hydrothermal environmental stresses and other related contents, so as to provide support for field management and yield forecast analysis. 2) Crop Planting Area Estimation: Identify different crop types by using remote sensing electromagnetic spectrum information, and estimate the crop planting area. 3) Yield Estimation: Estimate the yield per unit area of different crops, and calculate the total crop yield by combining the planting area. 4) Drought Monitoring: Establish drought assessment models using vegetation and surface temperature information from satellite remote sensing, or soil moisture information, to determine drought distribution, drought-affected area and drought severity, and estimate the potential impact on crop yields.
