Farmland ecological drainage method and regulation and control device thereof
The invention discloses a farmland ecological drainage method and a regulation and control device thereof, and belongs to the technical field of agricultural drainage and disaster reduction, and the farmland ecological drainage method is a drainage method for improving the farmland ecological environment by regulating and controlling the movement of water among a farmland, a channel and a pond and the movement of water in the farmland, the channel and the pond. The farmland ecological drainage method is realized by ecological drainage concept, ecological drainage engineering configuration and ecological drainage operation management, and adopts a drainage ecological flow regulation and control method. According to the drainage ecological flow regulation and control method, the ecological function deterioration of the farmland caused by flood and drought, salt and alkali and nitrogen and phosphorus loss pollution is relieved by controlling the ecological flow velocity of field drainage, the ecological flow velocity of channel transportation and drainage, the ecological flow velocity of ditch-pond exchange or the ecological flow velocity of external drainage. According to the method, the ecological drainage flow velocity is taken as a grasp, an ecological drainage regulation and control criterion, an ecological flow regulation and control device and a flow calculation method for coping with flood and drought disasters, salt and alkali hazards and non-point source pollution are provided, and the production and ecological dual requirements are considered.
本发明公开了一种农田生态排水方法及其调控装置，属于农业排水与减灾技术领域，其中农田生态排水方法是通过调控农田、沟道和塘堰之间及其内部水量运动以改善农田生态环境的排水方法，农田生态排水方法由排水理念生态化、排水工程构型生态化和排水运行管理生态化实现，农田生态排水方法采用排水生态流量调控方法，排水生态流量调控方法通过控制田间排水生态流速、沟道输泄生态流速、沟塘交换生态流速或外排生态流速缓解农田因水旱、盐碱和氮磷流失污染造成的生态功能恶化。本发明以生态排水流速为抓手，提出应对水旱灾害、盐碱危害和面源污染的生态排水调控准则、生态流量调控装置和流量计算方法，兼顾生产和生态双重需求。
