坡地檳榔園微氣候與水文之特性

Abstract

本研究於南投縣水里鄉上安村內，選取檳榔園設為試驗集水區，除觀測降雨量、地表逕流外，並另外設置6m 高氣象觀測柱，觀測全天日射量、淨輻射量、風向風速垂直分佈、溫濕度垂直分佈、地中熱傳導量、地溫垂直分佈等，除探討檳榔園之地表逕流與微氣候特性外，並進一步從氣象資料推估檳榔園之蒸發散量，以瞭解檳榔園之水文特性。 The fieldwork for this study was conducted in the experimental watershed of betel-nut orchard of Shan-Ann village located in the Shuli, Nan-Tao Hsied. In addition to the measurements of rainfall and surface runoff, one set of 6m tall observation pole was installed for this study. The global solar radiation, net radiation, vertical profiles of wind speed, air temperature, ground temperature and humidity, and soil heat flux were used.to determine the microclimatic characteristics and surface runoff of betel-nut orchard. The collected meteorological data were used to predict the evopotranspiration of betel-nut orchard. These information offer a better understanding of the hydrologic characteristics of this area.
