Abstract:: The spatial distribution characteristics of water conservation function and radiation benefit were analyzed via constructing a radiation benefit assessment model. The amount of radiation benefit and water conservation function were compared. The results showed that: (1) 75.40% of the study area was covered by deciduous broad-leaved forests and evergreen coniferous forests; loam and silt loam are the main soil types in the study area, these soils have the strong permeability, the mean volume of 234.75 m³ water and a total volume of 0.352 billion m³ water were conserved in the study area, the mean volume of 168.41 m³ water and a total volume of 0.214 billion m³ water were radiated in the study area; (2) 99.30% of forestlands have radiation functions and the actual radiation amount of forest patch accounts for 64.89% of the water conservation capacity, which provide the total amount of radiation of 0.191 billion m³; (3) 97.12% of grasslands and an average of 97.76% of water conservation capacity have radiation function, which provides a total amount of radiation of 2.2 billion m³; (4) 94.89% of farmland and an average of 92.98% of water conservation capacity have radiation functions, which provide a total amount of radiation of 24 million m³.
