- 摘要:
- 蒸发散量为一水资源涵养重要指标，据此，研究乃择定台湾西南部泥岩丘陵地上优势植被包括：番荔枝及莿竹，观测莿竹林冠层上进行全天日射量、净辐射量、气温、相对湿度及地中传导热量等微气象观测，藉以鲍温比与热收支法估测3种不同地表植被之蒸发散量，另配合蒸发散量实测值进行验证，可获知番荔枝及莿竹蒸发散量分别为：0.1~1.6 mm及1.9~3.6 mm，且与A型蒸发皿蒸发量之关系分别为0.27倍及0.74倍。
- Abstract:
- The dense canopy could be beneficial to conserve water resources, and the evapotranspiration had become an important index. The thorny bamboo and sugar apple tree could be a superior plantation on the mudstone hillside in southwestern Taiwan. The study aimed at the Bowen ratio and heat budget method to predict the evapotranspiration within sugar apple orchard and natural thorny bamboo plantation. The estimated evapotranspiration of sugar apple and thorny bamboo were about 0.1~1.6 mm and 1.9~3.6 mm, and proportions to A-pan evaporation were about to 0.27 and 0.74.
