【摘要】 针对江苏南水北调沿线平原自流灌区的特点,以大型平原自流灌区洪金灌区为例,按照干渠续灌、按条轮灌、分段轮灌和干渠续灌分级控制四种渠道工作制度,采用恒定非均匀流、闸孔出流等数学模型来推算渠道水位,寻求以灌区最大自流灌溉面积为目标的渠道轮灌工作制度,在此基础上,研制和开发了基于ComGIS的洪金灌区灌溉决策支持系统。更多还原

【Abstract】 The paper is in view of the feature of plain gravity irrigation districts along the both sides of the south-to-north water transferring project in Jiangsu province and takes Hongjin irrigation district, a large-scale plain gravity irrigation district, for example. Meanwhile, it is according to the following four channel working systems, namely main canal continuous irrigation, rotation irrigation by main canals in proper order or segment, and grade control continuous irrigation. At the same time, mathematical models such as the constant non-uniform flow and sluice gate opening discharge and so on are adopted to reckon the irrigation channel water level so as to seek for the channel rotation irrigation working system with maximal gravity irrigation area. On the basis of all these above, we design and exploit the irrigation decision-making support system in Hongjin irrigation district according to ComGIS.更多还原
