中文摘要 | 在水資源捉襟見肘之現階段,作物需水量不但是水資源規劃利用之重要參數,更 是灌溉計畫研擬與營運管理之依據,如何有效、即時、準確地測算作物需水量,冀以提昇水 資源之有效利用,實為從事農業水資源規劃研究者之要務。本研究係應用國際灌溉排水協會 (ICID) 於 1994 年所公佈之 Penman-Monteith 估算法, 以台北、新竹、 高雄等十地區自 1951~ 1990 之氣象資料,應用 40 年之平均資料, 輔以頻率年之觀念,確立臺灣各地區全 年之區域性旬別參考作物需水量 (ETO ),俾為不同區域不同作物於不同期作下, 即時估算 不同作物需水量之應用,並以本省灌溉用水需求量最多之水稻加以試算,比較分各期作水田 於不同重現期距與長時距之年平均值下,不同區域各旬別作物需水量之差異,建立臺灣各地 區水稻於不同期作不之旬別需水量與全生育期作物累積需水量,俾供水田灌溉用水管理與區 域性水資源規劃利用之參考應用。 |
英文摘要 | Nowadays, under the condition of depleting water resources availability , crop water requirements become not only the important parameter of planning of water resources utilization, but also the basis of planning of the operation and management of irrigation projects. It is therefore the task of irrigation organizations to estimate crop water requirements in an efficient, fast and accurate way, for enhancement of the effectiveness of water resources utilization. In this paper, the Penman-Monteith Evapotranspiration Estimate Model recommended by the International Commission on Irrigation and Drainage (ICID) in 1994 is applied. By using the meteorological data of Taipei, Hsinchu, Kaohsiung...etc.of Taiwan in the period of 1951 to 1990 and applying the concept of frequency years, the values of reference evapotranspiration (ET �� )in every 10 days for different recurrent periods in different areas of Taiwan are computed for estimate of the water requirements of various crops in different periods. Further, the estimate is made to irrigation requirements of paddy rice, the most demanded in Taiwan, which is then used to analyza the differences of the 10-day irrigation absolute water consumptions in paddy fields in different areas under various recurrent periods. The results are then applied to establish to establish the 10-day and the cumulative irrigation requirements in different cropping seasons in order to demarcate the reference zones based on the irrigation absolute water consumptions, for planning and management of regional water resources. |
