3、右。现状情况下水田实灌面积1.544万hm2，用水量2.1亿m3，而现有工程及天然径流可利用水量仅为1.7亿m3，尚缺水0.4亿m3。在充分熟悉灌区基本资料的基础上，论证灌区开发和进行综合治理的可行性、必要性、合理性。通过水文资料的分析审查，1993年的降雨量为十年平均降雨量的81.2。与规范所要求的设计保证率80最相符合，所以选择1993年为设计的典型年进行水量配合计算。根据水量平衡法计算的灌溉定额为420.02m3/亩。根据灌区的地形特点，充分利用土地、水利资源，进行灌区总体规划，布置了东海总干渠，裴德里总干渠两条干渠。合理布置撇洪、灌溉排水系统，布置水工建筑物、交通、防护林和居民点。推算
4、渠道流量、设计水深、加大水深和最小水深，以确定渠道纵、横断面形式等。通过对该灌区的规划设计，可以有效的解决作物生长期内灌溉用水紧张的问题。关键词：农业水利工程，灌区规划设计，合理利用水资源，灌溉排水系统，水工建筑物。AbstractThis design choice of title is dwells irrigation area planning and design.

In fully familiar with the irrigation area, on the basis of basic information, demonstrates the feasibility of irrigation are
7、a development and comprehensive treatment, the necessity and rationality. Through the analysis of hydrological data review, 1993, rainfall in 81.2% of the average rainfall for ten years. With the specifications required by the design reliability 80% most consistent, so choose 1993 as the design of t
8、ypical water with calculation. According to the water balance method to calculate the irrigation quota of 420.02 m3 / mu. According to the topographic characteristics of irrigation area, make full use of land resources, water conservancy, irrigation area overall plan, arrangement of the main canal o
