| Abstract: | The water cycling of hydrological processes of Phyllostachys pubescens Mazel ex H. de Lehaie plantation is analyzed in this paper. Precipitation and its allotting amount in the system and its seasonal changes are studied. The results show that: throughfall and stemflow in P. pubescens plantations increased with the increase of precipitation. There is an index relation between the canopy interception and precipitation. The annual canopy interception ratio of P. pubescens plantation is 11.1%, stemflow latio is 4.4%. The root system of P. pubescens has a greater effect on soil physical properties. As for the soil layer of o~60cm, the total porosity is 71.7%, final infiltration ratio 8.28mm/min. The yearly runoff ratio in the researched watershed 54.8%,surface runoff only 0.8%,interflow ratio 15.0% and underflow 39.0%, it demonstrates that there is a fairly good effect of water consevation in P. pubescens plantations. |
