研究方向 Research Interests

关于“生态水动力学” —— 这里的“生态”指农业生态系统,“水动力学”是我们的方法内核。课题组以水动力学为方法、以农业生态系统为对象,研究水在其中如何运动、如何与作物和生物相互作用,并把这种理解转化为智能感知装备与精准调控技术。

四个方向构成一条完整链条:机理认知(农业水动力学与数值模拟)→ 智能感知(智慧农田感知与无人系统)→ 精准调控(精准灌溉与水肥一体化智能装备)→ 系统评价(农业水土系统建模与可持续性评价)。

In our group name, “eco” refers to agricultural ecosystems, while “hydrodynamics” is our methodological core. Our four directions form one continuous chain: mechanism (agricultural hydrodynamics & numerical simulation) → sensing (smart farmland sensing & unmanned systems) → regulation (precision irrigation & water-fertilizer equipment) → assessment (water-soil system modeling & sustainability).


农业水动力学与数值模拟

Agricultural Hydrodynamics & Numerical Simulation

作为方法内核,本方向研究水动力学过程本身:面向输配水管网、灌水器和生物污损界面,开展沼蛤附着聚团与滤食行为的水动力学机理、微喷带与射流泵内流数值模拟等研究。发展 CDEM 与 OpenFOAM 耦合功能模块、基础冲刷计算程序等专用数值工具,实现水沙、多相流及灌水器性能的高保真仿真与生物污损阻力预测。

As the methodological core, this direction investigates hydrodynamic processes themselves. Targeting water distribution networks, emitters, and biofouling interfaces, we study the hydrodynamic mechanisms of mussel attachment, aggregation, and filter-feeding behavior, and conduct numerical simulations of internal flows in micro-sprinklers and jet pumps.

精准灌溉与水肥一体化智能装备

Precision Irrigation & Water-Fertilizer Equipment

作为调控出口,本方向把水动力学认知转化为可执行的田间装备与技术:围绕大型喷灌机、微喷带等灌溉形式,开展变量灌溉水力控制阀、隔膜式水控阀瞬变流动机理、管道内水肥混合运移等关键部件的水力设计与优化。结合北斗精准定位与农田传感信息,研发水肥时空分布模型,构建灌溉施肥智能决策与精准执行系统。

Focusing on large-scale sprinkler systems and micro-sprinkler hoses, we conduct hydraulic design and optimization of key components including variable-rate irrigation control valves, transient flow mechanisms of diaphragm-type control valves, and water-fertilizer mixing and transport in pipelines.

农业水土系统建模与可持续性评价

Water-Soil System Modeling & Sustainability

作为系统尺度评价,本方向融合农田小气候监测与作物生长信息,构建喷灌水-土-作物耦合模型,揭示灌溉对田间温湿环境及水肥运移吸收的影响机制。在区域与跨国尺度上,开展节水灌溉技术综合效益评价,解析人口老龄化对技术采纳的影响,为水土资源的可持续管理提供跨学科决策支撑。

Integrating farmland microclimate monitoring and crop growth information, we construct sprinkler irrigation water-soil-crop coupled models to reveal the influence mechanisms of irrigation on field temperature, humidity, and water-fertilizer transport and uptake.
