Abstract: Agrometeorological observation is an important cornerstone of agricultural modernization development. This study comprehensively sorted out the development process, business status and existing problems of agricultural meteorological observation in China, and discussed the development prospects of agrometeorological observation in the future, in order to provide a reference for escorting the sustainable development of modern agriculture and national food security. The development of China's agrometeorological observation operation has roughly experienced six stages: theoretical exploration, organization establishment, pilots construction, scale formation, optimization and adjustment, and stable and rapid development. At present, China has established a network of observation stations based on 653 agrometeorological observation stations (including 70 agrometeorological experimental stations) to carry out observation and research on crops, soil moisture, natural phenology, animal husbandry, fruit trees, trees, vegetables and agricultural microclimate. Based on the development of observation business, a national, provincial, municipal and county agrometeorological operational service system with scientific structure and advanced functions has been established. The national agrometeorological monitoring and evaluation, crop yield forecast, agrometeorological disaster monitoring and evaluation and impact forecast, agricultural weather forecast, meteorological grade forecast of occurrence and development of agricultural and forestry diseases and insect pests, agricultural soil moisture, drought relief, and ecological meteorological monitoring and prediction have been relatively mature and service results remarkable. In the past ten years, China's agricultural industry layout, planting structure and planting methods have undergone tremendous changes, and automatic observation technique such as automatic crop meteorological observation and automatic phenology observation have also developed rapidly. The agrometeorological observation operation also gradually shows a series of questions, such as the layout of the network of observation station and the observation tasks needs to be adjusted and optimized, the observation specifications need to be revised and supplemented, the modern technology and automatic observation equipment need to speed up the application and the operational service capacity needs to be improved and strengthened. From the perspective of the strategic deployment of the Party Central Committee of the CPC, the State Council and the China Meteorological Administration for the development of agrometeorological observation operation, the goal of high-quality development of agrometeorological observation, and the demand of modern agricultural development for agrometeorological operation, the future agrometeorological observation operation in China will gradually form a network of observation stations with reasonable layout, perfect specifications, advanced technical equipment, diversified and sophisticated service products, a modern agrometeorological observation and operational service system that can be in line with international standards.
