- Abstract:
- Phyllostachys edulis is a typical vegetation type of Jinyun Mountain forest ecosystem.By studying on the hydrology data in 2002-2007,the paper reveal the type of vegetation rainfall-runoff characteristics from the qualitative and quantitative,and of the process of change that the process of rainfall,canopy interception,surface runoff,underground runoff,soil,litter,and other factors of the distribution of rainfall.Research shows that (1) 2002-2007,Nanzhu of the annual rainfall distribution are relatively stable; more concentrated rainfall in April to September,accounting for 72% of annual rainfall,the peak in July.(2) Underground and surface runoff and rainfall response to maintain close relations.In the distribution of rainfall,surface runoff accounted for 30.7%,15.2% of the underground runoff.(3) In Nanzhu forestry,the largest soil of rainfall distribution to 19 mm,the largest litter of rainfall distribution to 4.6mm,canopy interception distribution of rainfall in 13.2%.The purpose of this study for the Yangtze River Basin forest ecosystem in the hydrological study species selection,vegetation and provide information and data support.
