Water Production Simulation in Hengduan Mountainous Region Based on InVEST Model
[Objective]To master water production and water distribution in Hengduan Mountains.[Method]Using InVEST model,the average annual water yield of Hengduan Mountains between 2005-2014 was evaluated and analyzed,and the spatial distribution characteristics of water production and their causes were analyzed.[Result]The results showed that the annual average water yield was 172.33 billion m3,which was relatively close to natural runoff.The spatial distribution of water yield showed a trend of increase from northwest to southeast in general.The annual average water yield and its spatial distribution was closely related to land use/cover type,soil depth,topography and so on.[Conclusion]The study can provide basic data for further study of hydrological processes in Hengduan Mountains,and provide scientific basis for regional water resources management.
