【摘要】 渠系水利用系数和水田耗水量都是灌区的规划管理、合理运行、水资源的合理调配等方面的重要基础资料,是综合反映灌区渠系工程状况与管理水平的重要指标,是编制用水计划和进行水量平衡计算的一个主要技术参数。但是到目前为止,沈阳市所属各灌区还没有切合实际的资料。本文通过室内试验确定了沈阳市十个主要灌区(石佛寺灌区、沈抚灌区、祝家堡灌区、浑蒲灌区、毓宝台灌区、八一灌区、大闸灌区、辽蒲灌区、浑南灌区和浑北灌区)各级典型渠道和水田的土壤质地,并进行了分类命名;通过田间双环入渗实验测定了以上十个灌区各级渠道和水田的渗透系数,并计算出渠道的渗漏量和水田渗漏量;采用彭曼—蒙特斯公式,以当地的1995年~2005年的气象资料为依据,分别计算出平水年以上各灌区各个生育阶段及整个生育期的水稻需水量;利用同期的气象资料计算出各级渠道平水年的蒸发损失;最后分别计算出沈阳市以上十个主要灌区各级渠道的渠道水利用系数、渠系水利用系数和水田的耗水量。最终将研究结果采用Photoshop和Excel以图表的形式分析和归纳出来,简明扼要,以便于沈阳市水利系统的各级管理人员和技术人员在进行灌区的合理运行、管理以及水资源优化利用和调配时作为基础数据参考和使用。

【Abstract】 Water effficiency of canal system and paddy field water consumption are important basic data in planning, management and reasonable operation of irrigation area, and rational deployment of water resources; which can reflect syntheticly the situation of canal system, znd managing level of irrigation area; which are the important parameters in water use planning and water balance calculation. But until today, there are still not practical data of them for the areas in Shenyang city.In this study, through laboratory experiment the soil texture were analyzed, and basing on it classified naming of the soils of all levels of typical canals and the paddy field in 10 main irrigation areas of Shenyang city were conducted (including Shifosi irrigation area, Shenfu irrigation area, Zhujiapu irrigation area, Hunpu irrigation area, Yubaotai irrigation area, Bayi irrigation areas, Dazha irrigation area, Liaopu irrigation area, Hunnan irrigation area and Hunbei irrigation area). Through field double-ring infiltrateon experiment, the soil penetration coefficients of all levels of canals and the paddy fields of the mentioned 10 irrigation areas above were accomplished, and according to them, canal and paddy field leakage losses were calculated. Using Penman-Monteith model, and based on meteorological data from1995 to 2005, paddy rice’s water requirement for average water year in the 10 irrigation areas during different and whole growing seasons were calculated. Meanwhile, the eavaporation losses for average water year were computed basing on the same climatic data. Finally, the canal water efficiency of all levels of canals, canal system water efficiency and paddy field water consumptions of the 10 main irrigation areas in Shenyang city were put out. The finally results of this research were summarized and expressed by tables or figures through Photoshop and Excel; which are clear and user friend, so that the complicated study results can be refered or used easily in reasonable operation, management of irrigation areas, as well as in optimized utilization, management, distribution and rational deployment of water resources for all levels of managers and technical personnels in Shenyang water conservation system.
