Abstract:

In recent years, there has been a "wandering phenomenon" in the development of agrometeorology, and some key questions need to be answered effectively. Based on system theory and resource theory, this paper deeply analyzed the connotation of agrometeorology, and expanded the relationship between meteorological conditions and agricultural (crop) production, and provided ideas and solutions to related problems. The results showed that the elements such as atmosphere, soil, crops and technical conditions make up the agrometeorological system. Climatic factors were not only natural, but also productive, and were involved in the whole process of agricultural production. The functional relationship between crop production and meteorological conditions could be established. Agrometeorological indices were the dynamic combinations of meteorological elements. Technological conditions could change the availability of climatic conditions and the sensitivity of agricultural production to climate. There were three properties of climate resources: quantity, space-time potential and quality. Different combinations of elements of the hydrometeorological system determine different objectives. This research could play important role in promoting agro meteorology.
