摘要
根据目前灌区灌溉管理存在的问题,将RS技术应用在灌溉管理决策中。提出了保证灌区实现良性循环以水价为计算因子的评价指标,并根据作物不同生长特性的光谱反映,在实现节水目标的前提下,给出合理的配水方案,使灌区实现节水增效的目标。
This paper applied RS technology in decision-making of irrigation management to settle the existing problem in irrigation management of irrigation district. The author put forward evaluating indexes with water price as calculation factor to guarantee the well cycle of irrigation district. According to spectrum reflection of various crop growth properties, under the precondition of realization of water-saving objects, the reasonable water distribution scheme was also presented in this paper to achieve the goal of water-saving and enhancing benefit.
