Abstract For studying a comprehensive evaluation method of landscape function for different land-use types in Loess region,we investigated and evaluated 150 plots by LFA method(Landscape Function Analysis)in Caijiachuan Basin,laid a total of more than 4400 meters transects.The results showed that: LFA method can be used to evaluate the effect of vegetation patches and soil properties of plots;based on LFA method,with weighted sum,the value of landscape function can reflect the effect of vegetation patches and soil properties of plots comprehensively;land-use types and slope have a significant influence on landscape function,and a calculation equation of landscape function value was established.The conclusions are as following: the multiple linear regression equation has reasonable structure and relatively high accuracy,which can be used to evaluate landscape function for different land-use types comprehensively.
