Agroecological geology groups and types are a comprehensive result from agroecological geology investigations, and are the basic units for the investigation and mapping. With a view on geological environment and agroecology system, the authors put forward three principles for distinguishing agroecological geology groups and types, which are dominant rules in the system, quality differences in agro ecology, and macro characteristics in favor of field investigations. There are 3 groups and 16 types, presenting remarkable quality differences in agro ecology in the research area.
