- Abstract:
- In order to explore evapotranspiration of hypo-vegetal defoliate and broad-leaved shrubs during rainfall process in the Upper Reaches of Minjiang River, an experiment had been conducted to investigate transpiration rate of the two preponderant shrub species,Quercus liaotungensis and Corylus heterophylla var.sutchuenensis.Franch both in June and August.The results showed that two species had higher average transpiration rate(Tr) in June than that in August, which was 1.6 and 1.5 fold in Q. liaotungensis and C.heterophylla var.sutchuenensis.Franch respectively. Tr decreased with increasing water content of branches and leaves in two species. However, Q. liaotungensis with a less Tr than that of C.heterophylla var.sutchuenensis at the same level water content of branches and leaves.The relationships of Tr to water content of branches and leaves were fitted with the power regression equations. Additionally,Tr was closely related to microclimatic factors and biomass of branches and leaves. It increased with increases of wind speed.
