| Abstract: |
| The primary representations of the vulnerabilities of water resource in Hengyang basin where is a typical hilly region with red and purple soils in south China are analyzed： the precipitation resource varies greatly in spatial and temporal distribution；the soils and rock property are not in favor of water and soil conserving；the structure of crops needs a high water consumption；and the farm irrigation works are timeworn and frangible．Some management countermeasures are proposed： constructing new water conservancy projects and improving old irrigation works，intensifying the utilization process of surface rainfall sources，and establishing water-saving cropping-forestry-herbage compound ecological system． |
