2012 年中華水土保持學會年會及學術研討會論文集 以移動觀測法測定小集水區內氣象特性之初探 [1] [1] [1] [2] * 劉虹廷 鄭靖翰 吳佳叡 唐琦 摘 要 本研究自2011 年8 月至2012 年9 月間，選定國立屏東科技大學水土保持戶外教室西南側有 一面積為 3.3 公頃之莿竹林集水區，依季節變化共進行 14 測回之氣溫與相對濕度調查，每次測回調查主 要參照該集水區內氣溫日變化分別於清晨7-8 時與午間 12-13 時有最低與最高時段來進行移動觀測，所得 結果分析得知，春、夏、秋及冬四季於清晨與午間時段，在小集水區內氣溫平均會較區外者偏低2～3℃ ， 其相對濕度會較區外者偏高 10~30%及維持在59~98% ，顯示莿竹林冠層覆蓋能具有降低氣溫與提升相對 濕度，進而具有緩和微氣候變化之效能。 關鍵詞：莿竹林、集水區、移動觀測、氣溫、相對濕度。 The Meteorological Properties of a small watershed by Mobile Measurement Hong-Ting Liu [1] Jing-Han Jeng [1] Jia-Ruei Wu [1] Chi Tang [2] * ABSTRACT This primarily study aimed at the application of mobile measurement to illustrate the meteorological properties in a small watershed. The experimental watershed within a superior species was thorny bamboo and located at the southwestern area of soil and water outdoor classroom of National Pingtung University of Science and Technology (NPUST), Taiwan, the enclosed area was about to 3.33 hectares, elevation 90-50 m, 223820.6N, 1203648.4E. There were fourteen measuring points were distributed uniformly with area around the watershed and one basic point was set outside the watershed. The investigated duration was over whole four seasons on August, 2011 and September, 2012, and applied the mobile measurement to observe air temperature and relative humidity had carry out in fourteen times. Since the air temperature would appear the minimum and maximum situation at morning 7-8 am and noon 12 to1 pm., and investigation should include the two periods in every round. The results could be summarized as follow. To compare the mean air temperature and the relative humidity inner the small watershed with its surrounding for the period of morning and noon in spring, summer, autumn and winter seasons , could find
