| Abstract: | The concept, theory and method to establish the Forest coverage ofthe optimum forest protective effect (FCFP) are presented in this paper, theoptimizat ion of forest area, quality and syace distribution will maxmize theforest protecting capacity (FPC),forest covering percentage (FCP) at maximum FPCis regarded as FCYP. The 68 counties of low montains and hills in Sichuan basinbeing tahen as an example, the FCFP to resist the largest erosion by localrainstorm in various forest qualities and distribution patterns is caclulated onthe basis of daily maximum rainfull over the years and water-keeping cayacity ofsoil respectively. |
