中文摘要：

节水灌溉是我国社会发展首要任务，针对目前响水灌区渠道输水损失严重的问题，运用模糊综合评价方法建立评价模型，对响水灌区的4个干渠的渠道输水能力进行评价。结果表明：渤海二干渠渠道输水能力相对较差，渠道水损失最为严重应予以重视，并且采取必要的措施。研究结果为响水灌区提高渠道输水能力、降低灌溉成本提供了科学依据。

英文摘要：

Water-saving irrigation is the primary task of China＇s social development. According to the serious problem oi conveying water loss of channels in Xiangshui irrigation district, the fuzzy comprehensive evaluation method is used to establish evaluation mod- el to evaluate the water- conveying capacity of four main channels of Xiangshui irrigation district. The results show that the water- conveying capacity of Bohai No. 2 channels is poor, the channel water loss is the most serious, which should be attached importance, and the necessary measures should be taken. The study results provide scientific evidences for improving the water-conveying capaci- ty of channels and reducing the irrigation cost in Xiangshui irrigation district.
