Abstract

With xichuan county as the research object,headwater conservation function is analyzed in 2004,2009 and 2014 by using the Invest model. The results showed that:(1)The headwater conservation function is better in western and northern regions of Xichuan,and is poor in the southeast.(2)The headwater conservation of the areas with high forest cover was significantly better than that of the areas with low forest cover.(3)The highest headwater conservation amount per year is arbor forests with 300.51mm,and the lowest is other woodland with 44.83mm. The order of headwater conservation amount of forest resources per year from high to low is arbor forests,shrub land,open forest land,immature forest land,nursery land and other woodland.

Key words： InVEST model; forest resources; headwater conservation
