Abstract:Spatial explicit data of precipitation contribute to water resource management as well as large-scale eco-hydrological processes modeling. In this paper, spatial interpolation model ANUSPLIN and Geographic Information System techniques were employed to simulate the spatial distribution of mean monthly precipitation in the mountainous region. Upper Stream of Minjiang (USM), where this study was carried out, is a critical area in Southwest China. USM locates between the east Tibet plateau and Sichuan basin, c...
