Crop production system and its management system

The definition，properties，structure and components of crop production system and the definition of crop production management system are explained．It was pointed out that crop production management system (CROPMAN) was an overlapping science of computer science，agricultural sciences and automation science,and its essential principles consist of crop simulation,crop management expert system and models for optimizing cultural measurements．The further development of CROPMAN would lead to high automation management of crop production．It was needed to integrate Geographic Information System，GlobalPositioning System，Remote Sensing，crop simulation and knowledge engineering into CROPMAN．
