摘要：Taking Hebi suburbs in the Limestone Hilly Region of South Taihang Mountain for example, we analyzed suitable vegetation types for different forest sites of degradation low hilly area of North China, and determined suitable vegetation types in different site types with quantitative method. The grey trend decision method of multi indexes was used, by taking the biomass, income, investment, erosion modulus of forest trees, shrubbery, grassland, and economic forest in a variety of site types as decision-making goal. The result showed that sunny, gentle slope and thin soil is suitable for grassland or shrubbery; sunny, gentle slope and gentle thick soil suitable for shrubbery or economic forest; sunny, gentle steep slope and thin soil suitable for grassland or shrubbery; sunny, gentle steep slope and gentle thick soil suitable for grassland or economic forest; shady, gentle slope and thin soil suitable for grassland or arboreal forest; shady, gentle slope and gentle thick soil suitable for arboreal forest or economic forest; shady, gentle steep slope and thin soil suitable for shrubbery or arboreal forest; shady, gentle steep slope and gentle thick soil suitable for arboreal forest or economic forest.
