中文摘要 | 本研究自2007 年3 月1 日至2008 年2 月12 日止,於臺東縣臺東市之新興地番荔枝栽植 區,擇一面積1.8 ha 且地勢平緩之試區(121°4’56” E,22°44’36” N),利用4 m 高度之觀測鐵塔 進行氣溫、相對濕度、地溫、風速、風向、淨輻射量及地中傳導熱量等微氣象觀測,並經比較 分析藉以探討臺東地區新興地番荔枝果園之微氣候特性,初步獲致結果如後。新興地番荔枝果 園內之氣溫與相對濕度多維持於20℃及68%以上,然遇寒潮過境初期未引發降雨時,則氣溫與 相對濕度均呈驟降趨勢。其間氣流之風速低於4.6 m s-1 及風向介於東北至西南,而當番荔枝果 園之淨輻射量約大於0.2 MJ m-2 時,其近地表土層始能吸收熱量,且當增加番荔枝果園近地表 土層內水分含量將有利於地溫維持於15℃以上,此能防護果樹免於寒害。 |
英文摘要 | This study was performed to observe the characteristics of microclimate for a sugar apple orchard at a reclaimed land of Taitung area. The selected sugar apple orchard (22°44’36” N, 121°4’56” E) had a size of 1.8 ha and was located at suburb of Taitung City, Taitung Hsien, Taiwan, within a gradual topography. The factors of micrometeorological observations included air temperature, relative humidity, earth temperature, wind direction, wind speed, net radiation and soil heat flux, and were measured using a tower of 4 m in height from March 1, 2007 to February 12, 2008. The preliminary results are summarized as follows. Air temperature and relative humidity were usually greater than 20℃ and 68%, but there was a decreasing tendency under cold wave with no rain. The daily mean wind speed was less than 4.6 m s-1 and the prevailing wind direction was in the directions of NE-SW. The topsoil layer of sugar apple orchard could absorb heat flux when net radiation was grater than 0.2 MJ m-2. Irrigation could increase soil moisture and resulted in an increase of earth temperature to more than 15℃, and the mitigation of cold damage for sugar apple orchard could be achieved under such condition. |
