中文摘要 | 在水資源規劃利用上,作物需水量為一不可或缺之重要基本資料,有效即時且準 確的估算作物需水量,除可確保作物之正常生長外,更有助於水資源之有效利用,故建立一 區域性參考作物需水量,以供作物需水量估算之應用,俾為機動配水管理上之參考,實為當 今灌溉事業管理者刻不容緩之要務。 因此,本研究之目的,擬蒐集臺北、新竹、高雄等十地區於1951∼1990之年平均氣象資 料,並應用國際灌溉排水協會(ICID)於1994年所公佈之Penmam-Monteith估算法,首先確立 臺灣各區域全年性旬別參考作物需水量(ET ),以為各作物於不同期作下作物需水量估算之 應用,進而以旬別移動法估算本省灌溉用水量為最大之水稻需水量,比較分析各期作水稻於 不同區域不同種植期距下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與不同 種植期距下之旬別需水量與全生育期作物累積需水量,俾供區域性水資源調配利用之參考。 |
英文摘要 | The crop water requirements become not only the important parameter of water resources planning and utiling but also the basis of irrigation schedule and operating management. Nevertheless, The distribution of water subject to time and space. The aim of instant estimation could not be approached and mobility of water management became perplexing. It is an urgent task of irrigation to estimation water requirement of crop rapidly, efficiently and accurately. 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 and Kaohsiung of Taiwan in the period of 1951 to 1990 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 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. |
