1、本科学生毕业设计设计题目:南芬管理区农田基本建设规划初步设计学院:年级:专业:姓名:学号:指导教师:摘要本篇毕业设计针对南芬管理区进行初步的农田基础规划设计。南芬管理区当地以平原为主,地形较为平坦,土壤比较肥沃,水量较为丰富,但由于原灌溉排水系统较为陈旧,规划不够完善,以及部分淤堵的情况,使南芬管理区原灌溉排水系统无法满足当前增长的农田灌溉要求,所以对灌溉渠道进行重新设计。保持原有支渠不动,在此基础上对旧的斗渠进行翻新,对无法灌溉的土地处新增斗渠、农渠,增加灌溉系统的控制面积;排水沟道采用设计排水沟与灌溉渠道排水相结合的方
2、法,在可以采用灌溉渠道排水的部分便不再增加沟道的设计,减少工程量,简化工程施工。灌溉渠道和排水沟道的设计都尽量根据本地地形顺势而为,减少工程投资。通过对南芬区的统一规划、合理布局、因地制宜、综合治理,改善当地的灌溉条件、生态环境、生产和生活条件;提高了土地产出率,增加粮食的亩产量,提高了人们的生活质量,为当地群众增加客观的经济收入。同时在规划灌溉渠道时,注重生态保护,将水土资源、森林植被、自然环境和社会环境进行有机的结合,把南芬区建设成农业、林业和生态环境等全面发展的农业综合区,为实现耕地总量动态平衡和土地的高效持续利用奠
