英文摘要：

Territory differentiation is no longer a term in geography. It involves not only natural evolution in the terrestrial ecosystem, but also economy, ecology, environmental protection, carbon emission and carbon -sink trade etc. , under the influence of human＇s activities. The national research on territory differentiation is mainly about agricultural land use, agricultural resources, and agroecolo- gy. More recently, it focuses on social and economic fields. The mathematical model and simulation are commonly used. Several high - impact papers are published and new research methods have been applied in recent years.
