渠井结合灌区农户灌溉用水模型的构建与应用

open access: yesShuitu Baochi Xuebao, 2021
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 ...

基于AquaCrop模型的库尔勒香梨生长动态模拟及滴灌制度优化

open access: yesShuitu Baochi Xuebao, 2023
为探究省力化栽培模式下库尔勒香梨园适宜的灌溉制度,依据4种灌溉定额(3 750,5 250,6 750,8 250 m3/hm2)条件下2年香梨的田间试验数据,通过冠层覆盖度、土壤含水量和蒸散强度(ETa)和产量指标,确定AquaCrop模型参数。设置不同灌水场景,综合考虑产量、水分利用效率和灌溉水利用效率,利用AquaCrop模型优化香梨灌溉制度。结果表明:Y2W3处理产量高出其余处理3.87%~16.86%,Y2W1处理水分利用效率高出其余处理2.88%~27.20 ...

浅析泵站运行管理现状及其改善措施

open access: yes水电水利, 2020
伴随着国家城镇化和经济的发展,泵站的作用越来越重要。不仅在地方农田灌溉方面起着重要作用,同时还要承担城市环境改善的责任。泵站运行管理涉及水力机械学、电力学、经济学等多种学科,是一项系统而复杂的工程。因此,有必要加大泵站运行管理的研究力度,对现有管理模式进行分析对比,找出合理的改进方式,以增大水资源使用率,推动我国水环境的可持续发展。本文主要围绕目前我国泵站运行管理的现状进行分析,探讨完善泵站管理运行管理的有效途径,为相关工作者提供一定的理论参考。

稻田水资源利用效用的灌排模式响应

open access: yesShuitu Baochi Xuebao, 2022
为全面揭示稻田水资源利用效用,在观测浅水勤灌(FI)、浅湿灌溉(WI)、控制灌溉(CI)和蓄水控灌(RI)处理试验小区田间水量平衡的基础上,建立了灌溉水、降水消耗通量区分方法及其利用效用评价指标体系,分析了水资源利用效用的灌排模式响应。结果表明:田间灌溉水和降水消耗量、有效利用率及水分生产力均受灌排模式的影响;2017-2018年各处理水资源消耗量为695.9~999.1 mm,其中CI处理水资源消耗量最低,并且消耗结构更加合理。CI处理的灌溉水生产力(IWP,5.392 kg/m3)、降水生产力 ...

Governing the Ungovernable: Mapping the Development of Groundwater Irrigation and Groundwater Policies in India

open access: yesWorld Water Policy, Volume 11, Issue 4, Page 1048-1064, November 2025.
ABSTRACT Groundwater governance is complex due to several externalities associated with groundwater being an invisible natural resource tied to the land with millions of extractors and limited means of exclusion. The paper traces the evolution of groundwater irrigation in India and the corresponding change in groundwater laws and policies to address ...
