The Loess Plateau was devided into 4 eco-economic belts — southern warm-temperate semi- humid agroforestry ( ); central warm-temperate, semi-humid and semi-arid agroforestry animal husbandry ( ); northwestern temperate semi-arid agro-stockbreeding (); and northern temperate arid and semi-arid agro-stockbreeding ( ) eco-economic bands via principal component analysis (PCA) and cluster analysis (CA) on GIS platform. These belts were further divided into 18 eco-economic regions. The discussion emphasizes regionalization and methodological framework for large areas like the Loess Pla- teau region. Such practice could be specialized supplement in developing appropriate regional eco-economic theory. Key words Loess
