在水文模型中耦合准确模拟农户灌溉用水行为的模块可以构建更符合实际的灌区水循环模型,可以定量计算农户灌溉用水对渠井结合灌区水循环的影响。以典型渠井结合灌区——陕西省宝鸡峡灌区为研究区,采用问卷调查与访谈的方式收集了大量的农业生产和农户灌溉用水数据,在深入分析灌溉用水影响因素互馈关系和渠井结合灌区水循环特征的基础上,采用Python语言构建了渠井结合灌区农户灌溉用水模型(HCLU模型),该模型由水文、作物、农户生计和灌溉行为4个模块组成,可以概化灌溉用水的各个环节并实现农户灌溉行为与水文物理过程之间的紧密耦合,定量计算灌溉水源、灌溉定额、灌水时间和灌溉方式等对灌区水循环的影响,模拟作物产量与灌溉量的关系,为灌区水资源可持续管理和农业种植结构的调整提供强有力的技术支撑。
A better hydrological model can be developed by coupling and accurately simulating the behavior of farmers’ irrigation
which can be adopted to quantify the influence of farmers’ irrigation on the hydrological cycle in canal-well combined irrigation district. In this paper
Baojixia irrigation district in Shaanxi Province was taken as an example
the question naire and interview methods were adopted first to collect data regarding to agricultural production and farmers irrigation practice. Then the factors affecting irrigation water demand and hydrological processes were analyzed. Finally
a Hydrological-Crop-Livelihood-Utility Model (HCLU) was developed by using Python language
which included hydrological
crop
livelihood and utility modules. In this model
hydrological processes
irrigation practices and crop management had been fully connected to quantify the impacts of irrigation on hydrological cycle and relationship between crop yield and irrigation. This model could be very helpful in terms of providing strong technical support for the sustainable management of water resources in the irrigation district and the adjustment of agricultural planting structure.
